Zinus Mattress Reviews

The worst business and absolutely appalling customer service. Liars. Purchased a mattress and decided to cancel order within 48 hrs due to the recent law suit. I spent 2 days emailing and calling without any results and then got an email that the mattress was shipped. I was furious. I then began to contact about the return and refund. Again, the same story, every CS rep I talked to, lied to me saying I'll receive a shipping label within 24-48 hrs, 10 days later, still nothing. The mattress is sitting unopened in my garage. I've filed a dispute with my CC and hopefully will get some money back. This is theft of my $500.

I purchased this bed 9 months ago and just turned it over to find mold all over the bottom of the mattress. It could only have come from the mattress because there isn't any mold anywhere else in my entire home. The company refuses to do anything about it saying it could be from an outside source. But how could the mold only be on the mattress and not even the box spring or anything else? I don't know how long there has been mold but there is a good amount so obviously a while. This has been making me sick and my allergies horrible. Last night was the first night without the mattress and I didn't wake up with a headache, my nose wasn't stopped up, and my throat didn't hurt. I feel disgusted that I have been sleeping on mold and that the company didn't care at all. I wish I never bought this mattress. These pictures show the mold with and without the mattress protector.

well i read so many reviews calling this mattress firm,i will tell you this,an 8 inch mattress goes to about 1 inch soon as you lay down on it,its like sleeping on the bottom of a crater,you feel like you need a step ladder to get out of bed,i am 6ft,200lbs,average build,it just engulfs me ,its like dropping a marble on a cotton ball,the marble has no support so drops til it reaches a bottom,my biggest fear now is when it engulfs me i will disappear from sight,help i been swallowed by my bed and i cant get out!!!

These are great mattress! This is the second one I purchased. I originally had a full size and then upgraded to a king size recently. I used the first mattress for two years at least and I am 140lbs and have no complaint, the mattress is still good and will be used in my guest room. The new king size is doing just fine.

Wow! I am impressed with this bed!
My husband and I have had a memory foam mattress that we purchased eight years ago from Sam's Club, and we have liked it, but we wanted to move from queen to king size. We shopped everywhere online trying to find the best bed for the lowest price. This is it.

Here are the things we experienced:
--NO smell at all. I am sensitive to smells and have asthma. Neither my husband nor I smelled anything. I put my face in the mattress right after opening. Nothing. Certipur is one feature I required, and I say it is valuable.
--Was expanded to 12 inches in less than an hour after unpacking. (Indoor air temp. about 75F. Outdoor about 87F that day.)
--Soft top half, feels like a pillow topper but with support underneath.
--Warm and cozy -- we will save on heating in the winter.
--NO stiffness in our bodies, noticeably no pain in the morning. This shocked us; we thought all memory foam would do that and that any soreness we had was just us getting older. Nope. This bed made a difference in our bodies.

My husband likes firm; I require soft. I am pear shaped and a back and side sleeper, and a firm mattress arches my back and hurts my tailbone, hips, and lower back. I have to have something that lets my booty/hips sink. My husband has scoliosis and lots of back pain and needs support. He is also a belly sleeper and needs support for that as well. We are both VERY happy with our sleep experience! I don't know how this is possible, but I guess it's the "Sleep Master" experience and the beauty of memory foam.

It arrived on time, in a box about four feet tall and wrapped in two layers of compression materials.
Here is our setup after removing the cardboard box:
We set up the box springs (two Twin XL) and frame. My husband handled the mattress by himself, unboxing it, pushing the rolled mattress down the hall, lifting it onto the box springs.
The instructions were simple and clear. We removed the first layer of packaging (which was a white plastic tarp-like material with reinforcement), positioned the mattress (still compressed in a second layer of clear plastic) in the center of the box springs and realized it was folded in half with the wrong side up. At that point, my husband and I had to lift the folded half to position it correctly with the zipper side down, and this was the most awkward part. Once in place, we removed the second layer of compression material. Magic! It started decompressing and was a full 12 inches in less than an hour.

I can recommend this mattress with confidence. We're happy, more-than-satisfied, and well-rested.
Sweet dreams!

I chose this particular model for several reasons. First, it is manufactured by Zinus. Now, Zinus does not have the name recognition of Tempur-Pedic, nor the same high-end reputation, or prices. Various Amazon sellers sell at on of assorted Zinus mattresses under a bunch of names, and they mostly get very good reviews. This model, a 10" Queen featuring 3 inches of memorey foam over "2 inches Pressure Relieving Comfort Foam," on top of 5 inches of higher-density base foam, appears to be identical to other brands that receive 4+ star ratings over numerous sales here. Add to this the fact that this particular listing was both shipped by and sold by Amazon, and I felt I couldn't go wrong. And, of course, my innerspring mattress was 15 years old and needed to replaced.
I received the mattress only today, and have only slept on it for a few hours, and will update this after a few weeks and maybe later. Prime 2-day shipping didn't fail me, and the 65 lb box was dropped right next to my house by FedEx. I handled the box fine myself but it was a little bigger than expected and without any handles, and a lot of people will definitely need help to move it up any stairs, if not move it all. Neatly packed, nothing extra, no cushioning needed.

Some reviews of memory foam mattresses led me to believe they can take 24-48 hours to fully expand from their compressed shipping state. Others caution you to have the mattress at least near where you will ultimately sleep on it before you unwrap it. The second bit of advice is defintiely worth mentioning; mine expanded and unfolded rapidly, reaching near-full dimensions in seconds. After wrestling it of the floor (I should have opened the plastic with it on the platform), I measured its height at 9 inches. Two hours later I found it a full 10 inches high. It is also a full 60 x 80, unlike many mattresses on Amazon that are undersized at 58 x 78 inches. That is a big deal to me - I want all of the 80 inch length a proper queen mattress provides, and filling out standard sheets without them being loose or baggy is a must.

I have not had a full night's sleep as of this review, but I did take a quick nap, which turned into a very long nap. It is comfortable. This mattress cradles me enough, yet is still firm enough to be supportive. Time will tell, but my initial impressions of this mattress are that it will be great to sleep on, and that it is a real bargain.

It is so darn comfortable that I don't want to get out of bed!! I seriously have no idea why I spent $1200 on my previous pillow top that was not even that comfortable to begin with when I could have been sleeping on memory foam this whole time.

There was no chemical smell at all that I could smell. Within 2 hours it was puffed up to full height and ready to go. I was expecting a mattress that was really firm from some of the reviews on here but it really isn't. It is soft and as soon as you lie down the foam melts around your body. I don't think I have had this quality of sleep in a long time. I am a toss and turn kind of person but not on this bed.

For the price you absolutely cannot beat it. I would recommend this bed to anyone, especially people who sleep on their sides. That is how I sleep and usually in the morning I wake up and my hips are in so much pain, but no more!

Just as a testament to how comfy this bed is...my son decided to climb into my bed in the middle of the night the first night I bought it because he wanted to sleep on the new bed. Usually he is up at 5:30. He slept in until 7:30 and even then I had to wake him up! I think I am going to buy one for his bed as well!

Great mattress, true 10" and no smell as other reviews claim to have... Medium firm awesome I let it breath for 8 hrs and perfect, it was ready to go within 2 hrs.
Buy with confidence you won't regret it.

My fiance and I have been using this mattress for a year now with no troubles. For reference, I weigh 130lbs and he weighs 330lbs, so you'd expect some sagging on his side, but we haven't noticed any yet. It's comfortable enough for a good night's sleep, although if I have a cat sitting on me, the uneven weight makes my hips dig into the mattress. For the price, this is as good as it's going to get. Highly recommend if you're looking for an inexpensive bed.

The most comfortable mattress I have ever laid on!!!! Buy it - do not hesitate. Worth every penny and more!!! Small chemical odor but I assume that will go away with time. Super thick. Medium firm.

This is a VERY NICE mattress and a wonderful addition to our guest room. It arrived as promised when the mail carrier drug it across our driveway and left it about 25' from the truck. The box was "solid" and felt much heavier than the 48 pounds the scales said. We used a hand truck to carry in into the bedroom. Having seen the warnings, I carefully opened the ends only to find what looked like a stuffed laundry bag. At first I tried to slip the bag off it but there was too much tension. So I took scissors and carefully slid them between the plastic mattress cover and the cloth bag. As I did it literally popped open on the box springs wrapped in a heavy plastic cover. After taking that off we opened it for the two day "airing out" period that was recommended. There was a mild odor at first that was gone by the second day.

The white cover was opaque so I couldn't tell for sure which side was the top (hint: the zipper goes down). We bought it for the guest room, but slept on it the first night. We didn't want something in there that we wouldn't like. It was EXTREMELY comfortable, and much more comfortable than mattresses costing double or triple the price that we tried. It is not a soft mattress, yet not too firm, but has a comfort that gave us a good night's sleep. The only difference either of us could tell with or without the bed board was that the sides didn't sink down as much with it -- so we left the bed board under the mattress. I suspect it would be almost as comfortable just placed on a floor without any springs.

One VERY MINOR "problem:" It is slightly larger than the box springs. As advertised, after it opened, it was 75x54x8. Full size box springs are 74x53. The 2" extra width is not a major problem and, as shown, is hardly noticeable. It does somewhat affect how much the side squishes down when you sit on the edge of the bed. The bed we put it on has both a headboard and foot board so the 1' extra length is not even noticeable.

I'm glad we purchased this mattress. It is a welcome addition and upgrade to the very old set we just removed from the bed and something our guests are sure to enjoy.

*** I did NOT receive this product in exchange for my review. I am not cool enough for that. ***

I ordered this mattress for my son, who specifically wanted a "mattress I sink into" to replace his aging Sealy "twin mattress that you give to your 8 year old because it was on the bottom trundle of someone's daybed for a decade and was slept on maybe twice but it's from a time when mattresses were FIRM like John Wayne's resolve!"

I did a ton of research. This product has nearly identical branding to three other mattresses on Amazon - identical documentation, identical "composition diagrams", everything. But it's $50 more. Why the price discrepancy? Because apparently Zinus is a real company that actually honors warranties. At least that's what I hear.

As everyone else indicates, this shows up in a duffel bag. The instructions are flat out wrong - it shows up folded in half and upside-down before being rolled up. You have to unroll it, unfold it, THEN flip it over, THEN cut the bag off. The only good news is that since I only bought the "full" it wasn't all that heavy. Then again, I'm a big guy. If you are a teenager or slender woman I would imagine this is not something you'd want to move all by yourself.

Once it's unfolded and inflated (which took about 24 hours to reach full firmness and regain its shape) it is a mattress sized (and shaped) chunk of memory foam so moving it around is unwieldy, but no more so than an actual mattress.

It is EXACTLY full-sized. And it is PERFECTLY rectangular. Just like the picture. It fits snugly (but not so snugly that we couldn't get a mattress pad and sheets on it) into the full-sized platform bed from IKEA that my son sleeps on.

When first inflated (for the first 24 hours) sitting up on the edge of the bed resulted in instantly crushing the entire mattress. The first time I climbed onto it, my knee touched bottom. That all changed within the next 24 hours. It is now firm, and even with my son sitting on me my hips don't bottom out. I'm sure I'm touching the support foam, but that's it. Sitting up in bed now results in a good amount of mattress supporting my butt. And I'm not light.

The included cover is decent - and zippered for removal so washing will be easy.

Now, the good part.

It's memory foam. In a 10" mattress. I took the zipper off and it indeed looks as intended - several inches of memory foam (hard to say if there's really a "comfort foam layer" or if it's just more of the same memory foam, as it's the same color) and several more of support foam.

It's REALLY comfy. As in "lie down and you don't have to toss and turn or adjust yourself or even really use a pillow because OMG it's comfy" comfy.

It retains its shape, it doesn't seem overly hot (it is supposed to be a cooler type of foam, after all) and it seems to be exactly as promised.

I will update this if that ever changes. And I might just have to buy one for my own bed, I'll be doing a sleep test this weekend!

All my roommates sat on this, and they each want one now. One even said it's like sleeping on a marshmallow. It came very nicely packaged. I had no problem opening it and airing it out for about 30 minutes. Description said it may have a natural foam odor, but I didn't even notice. Had it half a year and I've been able to sleep easier and longer.

Like many folks here, I bought this for my son (9 yo). Came vacuum packed, which is cool. My wife unpacked it and I carried it upstairs (she could've but that's how I roll). Real comfortable, especially for a kid. At 225 (think lean muscle and smoldering good looks) when I sit on the bed my butt does bottom out on the boxspring a bit, but once you distribute your weight you are going to feel like Han Solo frozen in carbonite (except you will be smiling).

I've been sleeping like a baby since switching to this mattress. Very pleased. It took approximately an hour for mattress to fully expand; left it on top of the pool table for a few days prior to moving it to the bed. Purchased the full size. Love that you cannot feel your spouse moving during the night. Will eventually change all of the mattresses in the house to this Ultima memory foam.

It's a bit taller than I expected (don't know why, it's as thick as the description states). Fits the space in our 5th wheel perfectly, much better than the crappy standard queen size bed the previous owners included. Just the right amount of tossing and turning at night (this is more important than you think, if the bed is so comfortable you don't move at all during the night you'll hurt quite a bit in the morning...this explains many "felt great the first couple weeks but then I got really bad back pain and had to throw it out" reviews that some mattresses get).

It's honestly one of the most comfortable mattresses we've had. Easily worth twice the price (though I wouldn't have paid that much). And the short queen wasn't much more than a regular queen, which made it an even better buy (short queen mattresses, common in RVs, generally cost much more than the larger standard queen, and quality often leaves much to be desired).

Please know I'm a Tempurpedic lover - I had the Cloud and also the Grand Bed. I bought this to sleep on every night because it's all that fits in a tiny room. I was hesitant because some said its not good for daily use, others said it smelled, some said it was cheap. I've slept on it 4 nights now and it's AWESOME. There was no smell at all (even when I opened it), I DID wait 24 hours for it to fully puff up before sleeping on it. I sleep on my side and I swear it's more comfortable than my old Tempurpedic. Laying on my back to watch tv is fine too. I wouldn't call it firm or too soft, the memory foam is just right for me and I have had NO back pain. I'm a skeptic so I am shocked at how great this really is. Give it a shot and buy it!!

First I must say I thought they made a mistake when I received the mattress. It was delivered in a box, well not use to seeing a mattress all fold up in a box. Once I opened it and placed it on the bed again I thought they made a mistake. I got a tape and measured the width it was not 8 inches as ordered. Well it just took some time to open up to it's correct size. After a year I have no issues with the mattress and if you are use to the spring mattresses you can feel the difference with this sleep master. I am thinking of getting another mattress and it will most likely be the same one.

This mattress went from the best mattress we ever bought to the worst, most uncomfortable mattress we'd ever slept on in under a year. At first we raved about this mattress and recommended it to a few family members and friends. Thank god they bought different brands because this has turned out to be one of the worst investments we ever made. Last year the mattress was about $75 more expensive and we didn't have a huge budget so we got what we could afford at the time. But maybe 7 months later we started finding it uncomfortable and here we are 1 year and 3 months later and we have just purchased a new mattress to replace it.

Basically it just doesn't hold up. It has absolutely no support. It is lumpy and painful. We feel the bed frame or box spring (we tried it with both) underneath when we sit down. At night when I roll over I feel my hips hit the box spring below at this point. Both my husband and I are miserable on it and have had back aches for the past few weeks.

Do not waste your money.

I was definitely leery about buying a mattress online. I went to Sam's Club, Mattress Warehouse, Bedding Barn, yadda yadda, and tried a million different mattresses. All of them were lovely, but none of them were cheap. Is this bed stellar? I wouldn't call it that. But it is a wonderful bed for someone who really doesn't want to spend much more than 200$ on a mattress, and someone who certainly doesn't want to try to haul a huge ass mattress on the top of her little Ford Fiesta.

PROS -

1. Cheap.

2. Cheap.

3. Cheap. Seriously, where the hell else are you gonna get a decent mattress for this price?

4. It comes to your house in a box. You open the box, open a bunch of bags, and the mattress gloriously unfolds for you. After having moved sofas and tables and desks and lamps into my apartment, it was MAGICAL to have something normally so bulky arrive and take pretty much zero work to set up.

5. It's a good mattress. I've had it for almost a month now, I sleep well, there's no noticeable comfort issues. Many of the negative reviews I read mentioned that it was too firm, firmer than they were expecting. I think that's because when people think memory foam, they think Temperpedic. See the con section below for more on that, but given all of the complaints about the firmness I was pleasantly surprised with the softness of it. It's firmer than I like, but it does kind of contour to your body. Also, unlike Temperpedic, this mattress doesn't trap all of your body heat! I hate waking up sweaty so this was a huge plus.

CONS -

1. Smallest con ever: it smells funny for like, 10 minutes after you get it. Really not a big deal though.

2. Do not expect this mattress to be a Temperpedic. If you've done any research on mattresses, you'll know that cheaper memory foam mattresses use a cheaper, different density foam than the fancy ass Temperpedics. (If you haven't done research yet, I suggest the Sleep Like the Dead website.) The skinny on these mattresses is that they run firm. And yes, this bed is firmer than I prefer. But see the PRO section above for why this doesn't matter to me that much.

3. Now I don't know this first hand, but I have heard that there's really not much you can expect in the way of customer service from this company. And honestly, if you order a bed-in-a-box like this, open it and find out 2 weeks later you really don't like it, what are you going to do? You can't ship it back, because there's no way you can squeeze the mattress back into the box. So I'd suggest trying out a bunch of mattresses, making sure that you're okay with something like this, I would say softer than a firm pillowtop, but firmer than a high density memory foam mattress like Temperpedic. Be REALLY sure you want to buy this before you place an order.

ALL IN ALL - This is a good, budget mattress. Generally speaking with mattresses you get what you pay for, but I would say this is a really good deal.

Perhaps this review will help you.....

Details: I am 5'10", 268 pounds, stocky, and was recently not-exactly-diagnosed with sleep apnea. My doctor believes I may have this issue, but without tests, hard to confirm. I had bought a Serta Plush Firm mattress that basically just got flat on top and was left with firm.

So, my review of this mattress is based upon the following:

1) Ease of assembly/setting up: The box they put this in was not exactly super heavy but was awkward to move around. Once I got it out of the box and on the frame it was super simple to set up. Remember: The zippered side goes on the bottom!

2) Inflating: I received the mattress around 2:15 in the afternoon and had on the frame by 2:40 (note: That is only 25 minutes). It was fully inflated in just a few hours and I slept on it that night. If you get the mattress and it arrives after 7PM, let it inflate and sleep on it the next night.

3) Smell: Unlike others I did not have any type of overpowering smell. It just smelled "new." TIP: If you think you may be bothered by the new smell, run your sheets through the washer and use some Snuggle concentrated fabric softener. It's got a great smell and will counteract any "new" smell of the mattress.

4) Firmness: When you first crawl onto the bed it feels a little firm, but then you sink into it and it really does conform to your body. I always lay on my back and watch some TV when I first get into bed at night. The first night I turned the TV off and laid to my left side. I felt the mattress firming back up to conform to my body.

5) Adjusting: With my old mattress I had to toss and turn several times before I finally got to sleep. I ordered this mattress on Halloween and it arrived 2 days later thanks to Prime. Every night since (over three weeks now) I got this mattress I roll over after turning the TV off and I am asleep within 5 minutes! I have not had to toss and turn any night since to get comfortable and fall asleep.

6) Other: With my old mattress during the day I was constantly having to turn my body to try and "pop" the bones around my lumbar area. I'm not doing any of that any more. Also, I would wake up previously and have to stretch my legs and they would just pop from no getting good support. They are not doing that any longer, either.

7) One person said you may not need a pillow and I think another said you will not need two pillows. I am not so sure about the no-pillow option but two will definitely not be needed. I bought a memory foam pillow a few months ago at Belk. It was an Isotonic something or other, and it has relieved all of my neck pain. It was the precursor to getting a memory foam mattress.

8) Heat: I have not had one problem with heat, and I am hot natured. I have bamboo/rayon sheets and they are very breathable and soft. I have an alternative-down memory foam comforter on top of that. I keep my house around 65 year round.

9) Overall: I would recommend this mattress to anyone who asked, and I would purchase again if I had to do all over again.

I hope this helps. Any questions? Feel free to comment and I'll be happy to answer!

10/18/2014 UPDATE: Almost one year later and I am still loving this mattress! The side I sleep on has held it's shape greatly. I am thinking about turning it around on Halloween (1-year- anniversary) to see how the other side compares since I have slept on the same side a whole year. As of today (10/18) the mattress is on sale for almost $100 off! You can't go wrong with this mattress. Also, about the heat: I dropped the bamboo sheets as they were crap! Going back to regular cotton sheets was a tad warmer, so just lower your A/C at night and you'll be fine!

I am a chiropractor for 30 years. This is the best bed of all time and the best price on the internet. The bed completely conforms to your neck and body. You don't even need a pillow. I would do a commercial endorsement for free.

I went back and forth on buying this. I was raised with the "you get what you pay for" and "if something is too good to be true, it probably is" mentality. So when I saw this, for the price here, I was skeptical. The reviews were overwhelmingly good, but with my bad back, I was really wary about buying a bed without testing it out, buying a mattress for less than $300, and very concerned about how I was going to make do if it didn't work out. But, being on a budget, the choice became this or a donated futon mat... It didn't take long to make the choice after that.

The bed arrived in a box about 18" x 48" x 18". Looked a little bit like a cardboard coffin, actually. It came upstairs with little fuss (it was heavy, but not too bad), and we opened it up. The packaging was secure, and thick enough that I wasn't worried about cutting into the mattress. YOU DO HAVE TO BE CAREFUL IF YOU USE SCISSORS. There is a little room within the box, but not much.

We don't have a box spring yet, so the mattress went onto the floor directly. Within minutes, it was fully puffed up, and so comfortable, I couldn't believe it. We added a thin bedspread to it for extra padding over the sheet, and that did the trick to balance out the lack of bed frame or box spring. The smell that people talk about was gone by the time the bed was done expanding, but I would recommend you open a window or leave the door open, or even turn on a fan, while it's doing its thing. If I'd left the room closed up, the smell could have been overwhelming.

So, the rundown:
* Great price
* Easy to set up
* Works with bad back
* Cushy, but not overly so
* Not too firm, just about right
* Even comfortable on the floor
* Smell, but not overwhelming and gone quickly

I was skeptical about this bed, so cheap. Let me tell you I have not slept better than this in the past 10 years. I work 2 jobs, and have chronic back pain (bulging disks). I wish I would have found this bed years ago.

Excellent mattress! I've had a tempurpedic for 10 years and it was time for a new mattress. I've had 10 spine surgeries and 7 spinal fusions and this mattress is amazing. No pressure points and you don't over heat like the older tempurpedics. A great deal!!!! Couldn't be happier

This product is not the same as a full size bed, It is much smaller. I have no Idea how to send this thing back?
Looks like it would be comfy but does me no good the way it is...

This is probably the most comfortable mattress that I've slept on. On our old mattress, I would go to sleep at 9:30pm and wake up at 5:45am. I figured this was a good schedule to me. After getting this new mattress, I've gone to sleep at 9:30pm but have woken up at 4:30am, having not moved at all. After that I toss and turn for another hour until it is time to get up because I'm already fully rested and don't need to sleep anymore.

For me, this mattress is not too firm nor too soft. For some, it may be too firm, as this "memory foam" is not the same stuff as the higher end brands. That is neither praise nor critique. Whatever the foam is (3 different layers of different foam), I'm loving it.

I searched for a while and could find no videos on this mattress so I posted one on youtube. You can find it by searching "Sleep Master 12-Inch Pressure Relief Memory Foam Mattress" and look for the video with the thumbnail reading "Sleep Master Mattress Unboxing".

It's been a long time and this mattress remains in the same condition as when I bought it. It hasn't lost any of the characteristics I've been loving throughout these years.
I've been sleeping on it on a daily basis with not a single minute of regretting.
6' tall, 260lbs, and sleeping really well, I have not experienced temperature problems, loss of firmness, deformation, or any other so far, so I thought it would maybe be of help to others to do this update.
My original review (below) stands after all this time, and I still recommend this product.

I find this to be a great product.
As my bones have grown older and my joints crankier I've tried several different mattresses, some better than others, some pricier than others, but for the first time I can say this is simply the best one I've slept on so far.
It is soft enough while firm enough as to provide great comfort to a person like me, with joint-related issues. I can sleep all night without having to wake up to move for a while and without more tossing and turning. I wake up in the morning fully rested, with no pain or discomfort whatsoever.
In my case, I did not experience the problem of strong chemical odor other reviewers have referred to, the mattress expanded really fast and evenly, and after a fairly long trial period I am completely satisfied with the product.
I will not say it may be the best mattress out there, but it is the best of the many I've tried, and the price is excellent.
I will keep it.
Great product. Highly recommended.

I will start by saying that it is VERY rare that I would take time out of my schedule (even 15 minutes) to write a review. This mattress however deserves a positive review of more than 5 stars if that were an option. I currently own one of the original foam Tempurpedic mattresses. It is 10 years old and still in great condition. My situation is that I have recently had a major back surgery. A fusion from L4 L5 S1. With being off from work during my recovery, I have taken on a temporary roommate to assist with bills and mortgage. I moved from my master bedroom to my spare bedroom to accommodate my roommate whom I need more than she needs me. Anyway, the smaller bedroom would not accommodate my queen size bedroom set so I chose to put a twin size bed in my room. I then had to find a preferably foam mattress for a twin bed. I read many reviews on foam mattresses and compared pricing on multiple sites. Trust that I have done this research for you and you need not look any further! I am a flight attendant and I can say that I have slept on hundreds of beds across the United States and beyond. This mattress is amazing and comparable to my queen size Foam Tempurpedic that cost a couple thousand dollars! I am still healing from my fusion surgery and I am so impressed with this bed's ability to conform to my body. As a curvy women, the bed gives where it needs to. I don't feel as though I sink down into it. It is soft yet supportive. I have invited friends and coworkers to sit and lay down on this bed and they have all been very impressed also! A couple have already stated that they will purchase this mattress themselves. When I require a new foam mattress or if I decide to upgrade to a king size bedroom set, this will be my mattress of choice! Do not waste your time or money on any other mattress besides this one!

I bought this mattress to replace my 12+ year old memory foam that was 8 inches in depth and has served us very well. It too was an online purchase in an effort to have the comfort of a memory foam and not the expense of a Temper Pedic. We just took off the old mattress, unwrapped the new mattress and put it on our bed. Within 5 minutes the thing had already expanded to it's full 12 inch height and completely filled our California King bed frame. I took the liberty of falling down on it just for a dry run through since I know we need to let it set for approx 24 to 48 hours for it's full expansion. Gosh, it was like falling into a cloud. My husband and I are in that middle age spread thing with plenty of arthritic joints to go around and this mattress should fit the bill of supporting all those achy spots the old mattress had stopped supporting.
I read other reviews that mentioned the bed was hard, but ours couldn't be softer. Another mentioned that they repeatedly got defective, lumpy mattresses, ours was perfect first time out of the box. It is in fact, softer than our previous memory foam and there was little or no odor coming out of the plastic wrap. I am genuinely tickled pink with this purchase and look forward to sleeping like the dead on it. What an awesome buy for the money and can't recommend it enough!

Great bed. Very quiet. No issues with springs or creaky wood box spring. Only critism would be that the foam holds heat. I purchased mine when it was still warm and I have been waking up sometimes in the middle of the night sweating. Hopefully it will be the opposite in the winter time.

I bought this mattress for my apartment in the beginning of January based on the overall good reviews. One month later I regret it.

The good:

Shipping & Delivery -
The mattress came in just over a week (without prime shipping) and was packaged in a box that I was able to easily take from the storage area of my apartment up the elevator and through the doors that led up to my room. I was also able to quickly and easily unpack the mattress and let it air out to its complete 8" size.

Mattress Quality (first 2-3 weeks) -
For the first 2-3 weeks of owning this bed it was great! My sleep quality considerably improved from my old mattress and the memory foam retained its shape and supported my body throughout the night.

The bad:

Mattress Quality (1 month in to present) -
Around the 1 month mark I started to have back pain and began to pay attention to how the bed felt as I got into it each night and what it looked like once I woke up in the morning. The mattress had begun to lose a lot of its shape and the memory foam was supporting my body less. Instead, I was just sinking into the mattress and it was no longer providing the support I needed.

Overall you get what you pay for - a bargain price for a cheap memory foam mattress.

This 8 inch memory foam mattress is working well on a foldable frame, without a box spring. I like memory foam, and I found it comfortable. It does "dent" for a while after using it, but does return to original size within a few minutes. True to size, sheets fit well. Would buy this again if the need arises.

Bought three Twin Sleep Master 8" Memory Foam Mattresses. They arrived on time and after letting them expand for a couple hours they were ready to use. They don't have any worse odor then any other foam mattresses we've had and it goes away after awhile. They're pretty firm and perfect for my kid's bunk beds. The kids are satisfied and that makes me satisfied!

better than I expected ..great buy for the price bed is comfy not too hard not to soft just right

This bed is soooo amazing!! I was skeptical about buying a bed online especially after reading a lot of mixed reviews but I was pleasantly surprised. This is the best purchase I have ever made. The mattress is soft yet also firm and it conforms to your body. It did not have a smell and expanded fully after a few hours. It's like sleeping on a cloud and it does not get hot. It is actually pretty cool, I would have to confirm in the summer time though. I also bought two 8 inch twin beds and my kids love it. I just hope that it lasts at least 5 to 8 years. If it does it is definitely worth the money versus buying those expensive mattresses in the stores.

We let the mattress expand on the bed frame (right on the wooden slats) and it filled in.....even though the size of the bed is different than a full size it didn't matter! It is extremely comfortable! I'm so happy that I didn't spend the money on a 3/4 mattress.

First off, I bought this product in the twin size a month ago for a spare bedroom loft. I was pleased with the product. It is delivered compressed, and when it was unpacked, it sprung to life very quickly and evenly. Because I was pleased with it, I ordered a queen for the same spare bedroom. This was a completely different experience. After unpacking it, I was surprised how uneven it appeared, but since it had been compressed and I knew the instructions said to wait 48 hours, I didn't worry about it. Now 48 hours later, this is a mess. There are parts that are very nice, but there are edges that haven't risen back up, and sections of the mattress that are inches lower the the higher points. If you would run your hand down it, it would be a lump after the other.

I would not recommend this because of the second experience.

Now that's an AWESOME bed! We've been building up our camper trailer for a year now and finally got to install the bed. This last weekend we got to try it out and see about any changes needing made. The mattress is sitting right on the board over the bed frame. I was really cool unpacking it and seeing it "inflate", we let it set in the trailer for 2 days, as I cleaned out all of my tools, and scrubbed the trailer to get lived in for a weekend. My bride kept saying "You're gonna love this" but I was dirty from all the work and didn't want to try it out and mess it up.
In our house, we have a king sized pillow top that is pretty good, but I have been still waking up stiff. After two nights on this one, I'm simply amazed that I'm waking up rested again. I have knee, back, and neck injuries from my military service, so living with pain is normal. The wife may have to order a king sized just to keep me sleeping in the house!
BTW, we have the 8 inch thick mattress and it's actually more like 10 inches. I'm 180lbs and I can feel myself sink into this one a couple of inches. Not one pressure point. Don't even consider the thinner ones, the 8 inch is it!

I bought this March and it is now mid-May. It is firm like others have said, but for me that works because I've always had firm mattresses. It does stain easily but I scrubbed it a little and it came out easily. Nothing sunken in parts yet, I'm about 110lb on my fat days and I sleep on one side consistently. It does what it's supposed to do. I also didn't let it inflate for 3 days like it says...I got tired of sleeping on a blankets on the floor so I decided to just sleep on it after like one or two days. I got the queen sized, 8in which is great. I probably wouldn't go thinner than that. SO is 160lb and when he sleeps over he has no problems either. The smell faded away quickly and I also grew to kind of like it (associating it with bed and being happy versus the disparity and depression that consumes my life). I used a mattress cover to remedy the stain thingy. IDK, I think it's a good purchase if you're at that awkward time in your life where you don't want to spend $800 on a mattress but want something comfortable for a few years.

Over a decade ago, my husband and I saved for a very very long time, and spent what to us was an absolute fortune for a mattress at one of those mattress selling brick and mortar shops, thinking we would splurge for high quality on something we would use every day. We were greeted with a hard sell, as if we were about to buy a used car, and they even tried to throw in a baby mattress to close the deal (we didn't have a baby at the time, but we certainly could have used a toaster). I wish we had been able to purchase this excellent mattress by Zinus, Inc. back then!

We received this Queen-sized Sleep Master Ultima Comfort 8" mattress, and it came delivered to our front door, vacuum-sealed, air sucked-out, folded-in-half and rolled into a small package (considering how big it was out of the box)- at a cost that is multiples less than the bedding in our house (i'm embarrassed to admit that we bought a few more of those outrageously priced mattresses as our family grew). But most importantly, I would say that our Sleep Master Ultima Comfort is equivalent in quality and comfort to our store-bought mattresses.

If you are in the market for a mattress, i suggest you take a leap of faith and spend the few hundred on one of these. There is a good chance you will not want to trade "up" (in price, that is) to another mattress after you try this one. 'worst case scenario, someone in your family will like it, or you can use it in a spare room.

This 8" Queen came in a cardboard box, approx. 4'x2'x2'. In the box was a disposable white drawstring outer bag (you rip this open, don't cut). Within that was a clear vacuum sealed bag (this one you carefully cut to let the mattress expand). The mattress itself is comprised of two fused foam layers covered in a gauze (see last pic), and it has a soft white removable terrycloth cover. The bed sprang up to 6 1/2" within a minute or so of breaking the seal of the clear vacuum bag, and it expanded to the full 8" within 10 minutes. The terrycloth covers the top and sides of the mattress, and the bottom has a thicker tan fabric. There is a zipper around the tan bottom on three full sides of the mattress, making removal of the cover very simple for cleaning. There is even a fabric "tunnel" for the zipper at the end, so that the zipper head tucks in, and no metal will touch/ snag your sheets. nice touch!

The inner mattress consists of a denser upholstery-like yellow foam (6 inches) fused to the bottom of an upper 2 inch blue layer that feels like a Tempurpedic memory foam. The mattress is Goldilocks in comfort, not too hard, not too soft, and even though i'm a firm mattress person, i find this mattress very comfortable despite myself. Both my husband and i are more slender, however, and it's possible that larger or heavier individuals may find this mattress not providing enough support (it is still foam, after all). By contrast, when my lighter (under 100 lbs) kids lay on this, they barely make a dent.

If this mattress even lasts one year, i'd think i would have gotten my money's worth. However, seeing how well this is made, and how good it feels to lay on, i don't think it will be a problem for much longer term use (my 10 yo foam couch is still going strong, why not this?). This is a great mattress for a super price-- and, no more trips to negotiate with mattress sales people!

I paired the Zinus 14 Inch Elite SmartBase Frame, Full with the recommended Sleep Master Ultima Comfort Memory Foam 8 Inch Mattress. Both by Zinus. This set is replacing an IKEA combo that my 7-year-old daughter had been using up to this point.

In comparison with the IKEA mattress, the Sleep Master Ultima blows it away in terms of comfort. Both my wife and I have occasionally slept in our daughter’s bed (when she was sick or scared) and the IKEA mattress made that a very uncomfortable chore. Being that my daughter is small and light, it wasn’t that big of a deal for her, but as a 199lb man I could feel the uneven pressure against my back. Me and my wife tested out sleeping on the Sleep Master Ultima and it is a dream in comparison. Very soft and comfortable with even support, but still has a good amount of resistance. It is well balanced. Even my daughter says it is more comfortable and she has been sleeping later than normal, and is tossing and turning less during the night.

The 14 Inch Elite SmartBase might be a little overkill as it is the more durable option in the Zinus inventory. More expensive, too. But because I’m sharing the bed with my daughter from time to time, I like having the added support to protect against the added weight. Not to mention my daughter has been known to stand and jump on the bed with her friends when we aren’t watching. That said, it’s also larger in size when folded and makes moving more difficult than Zinus’ more compact bed frames, so keep that in mind.

The feet on the frame have rubber ends with grooves, which makes it good for hardwood floors or carpet. I was impressed with how sturdy and solid this frame was; it didn’t move around or make noise when shifting weight on top.

The SmartBase is easy to setup; no need for screwdrivers or other tools. You simply unfold it, align the arms, and tighten the wing nuts to keep them in place. I didn’t even need to open the instructions to figure it out; very simple and easy to understand. It took me about 15 minutes total to get everything in place.

The mattress came in a fairly small box (being a Full size mattress), and was easy to carry and unpack. (I could see larger mattresses needing an extra set of hands or a dolly since the weight can add up.) Removing the mattress from the box was simple, and it comes in a special bag (made from a tent-like material) that rips open. The mattress lay out on the base perfectly and it only took a few minutes for it to puff up with air. Although Zinus does say it could take up to 48 hours to return to its original shape. I’d say a few hours is enough to sleep on it comfortably.

Now, there are a few negatives I came across. Firstly, the SmartBase does not have an attachment for a headboard. Why this isn’t standard is beyond me. If you have or want a headboard, you’ll need to spend another $20 or so for the Sleep Master Headboard Bracket sold by Zinus. Seems kind of a rip off, but that’s how it goes with these frames. If you don’t need a headboard, then no problem there. The other item is the Zinus Non-Slip Pads for Mattresses & Rugs (Set of 2), also retailed around $20. And let me tell you, if you do the same mattress and frame pair that I did, you will likely need them. The mattress does slide quite a bit on the frame. Thankfully for me, I was able to push the bed against two walls so the sliding and shifting isn’t as much of an issue; the walls hold the mattress in place fairly well. But if you put the bed in the center of the room, I’d totally recommend getting the pads.

Interestingly enough, I found that the Aveline 10" Gel Infused Memory Foam Queen Mattress made by LexMod works better on the Zinus frames than the Zinus mattresses. Why? Because there are small rubber beads on the back of the Aveline’s mattress pad. These keep the mattress in place much better, and a need for a pad is less necessary. My wife and I have this mattress on our Zinus 18 Inch Premium SmartBase, so I can say this setup seemed to pair better for me. Still, if you don’t mind paying extra for the pads (or have your bed up against two walls like we do) they are very well rated and seem to work effectively.

Overall, this is a good setup. The 8” mattress is a perfect fit for my daughter, but if you are a side sleeper like me, you might want to consider the 10” mattress. 8” is best for back sleepers. The frame is solid and doesn’t shift around, and it is true to the claim of being noise free. Also, it’s a great replacement for the bulky box spring. I was very happy to toss out the old IKEA mattress in place of the Sleep Master Ultima. If you get the mattress, just be sure to order it at a time you plan to open it shortly after. If you leave it in the shipping box for too long, it could hinder the memory foam expansion. Zinus recommends opening it within 72 hours of receipt.

I've had this bed for about a year now. I remember being a little skeptical when first buying it, but I can confidently say this is one of the best purchases I've made on Amazon.

When it first came in the mail, I was surprised with how small the box was. After I opened it, the mattress quickly expanded. The only odor was that of freshly processed materials, which quickly vanished once it was left to air out. Even though it says to let it air out longer, I slept on it the first night without any complications. It expanded to its full shape uniformly.

It gives me the support I need, even without box springs (My bed is an IKEA Brimmes model with the Luroy slatted bed base, for reference). The foam gets a little warm in the summer, but that should be expected due to the thermal properties of the foam. It should be noted that this mattress is on the firmer side, so keep that into consideration when ordering.

As a college student, one of the best features of this bed is that it can easily fit into the backseat of my car. I recently moved for an internship, and I was nervous about transporting everything safely. But this little guy easily conformed to the backseat. I even put more boxes and other items on top of it, which really helped to optimize space. When it came time to take the mattress out, it popped back to its original shape. It was like it was never desperately stuffed into an awkward shape.

On that note, since this is a memory foam, I love the homogeneity of this mattress compared to spring mattresses. Every sleeping position is comfortable, and your weight is evenly spread no matter how you lay.

Overall, I'm extremely satisfied with this mattress.

TL;DR great support, easy to move, awesome deal, won't need to count sheep, 10/10 would purchase again

I just received this mattress this morning and I immediately put it on my frame. I did not notice any odors and it fits the Queen frame I bought perfectly.

FYI - the delivery box was pretty heavy and very hard to pick up.

After 3 hours I measured the thickness @ ~9" (seems the head board and foot board ends and the exact middle are noticeably higher.) I will wait until Monday or Tuesday to take a final measurement and sleep on it. I am thinking I will need a low-profile box spring or similar and a cover/pad; but I will sleep on it first. I foresee updating this to 5 stars when all is done.

This bed is great for someone looking for a very plush soft mattress for a child or small teen. I would not recommend this for anyone over 150-175 lbs. My SO and I weigh a bit more than that and we needed something a bit firmer and taller. When I layer on my side my hips hit the slats of my bed, the same thing when I payed on my back. I thought the 8" would be the right density and size for us but it seemed like this never expanded past 6 1/2-7 inches in some spots. I left it alone for DAYS, still nothing, so I went through the arduous process of returning it. Make sure you contact the large returns department on Amazon. They were extremely helpful if I could give their service a 500 star rating I would. They had to send a special shipping company to pick up the mattress since it was already expanded and impossible to get into any shipping box UPS would pick up. Amazon was wonderful in the return process. Refunded me my money before I sent this back so I could purchase a replacement for this and waited till my new mattress arrived and expanded before arraigning pick up of this mattress. Stellar service from Amazon.

I gave this 5 stars because after a week of soreness in my back and neck, this sucker took it right out after a good night's sleep. Rolled out quickly and decompressed well, super simple. Feels luxurious and not hot either!

I feel like myself again!!!

Without a doubt one of the best purchases I've ever made. I spent weeks researching different memory foam mattresses, sizes, and platform frames. About a month ago, after much research, I decided this mattress best matched my preferences. (I wanted a mattress that was cloud-like and soft on top with enough support in the bottom that it doesn't feel like I'm sinking) I'm so glad that I decided on this mattress. when the mattress arrived I opened the package and within 10 minutes the mattress expanded to the full 12' size, even size all around, a perfect square and perfect edges. I purchased a wood- slat upholstered platform frame, which turns out is perfect for this bed. I'm glad I decided on the 12' mattress because the platform is low to the ground but the big mattress makes it about normal height. The slight foam smell was gone by the next day. The mattress itself is the perfect balance of comfort and plushness, along with support. definitely the most comfortable mattress i've ever slept on, and this is after a full month of sleeping on it. Why anyone would pay over $1200 for a memory foam mattress when they could purchase this mattress for a quarter of the price is beyond me. This is definitely the perfect memory foam mattress for anyone in the market for one. Do not hesitate and waste your time or money elsewhere. I've slept like a baby for the last month and I'm planning on updating this review every few months or so!

Update 12/20/2014 - 4 and a half months in, I still love everything about this bed. Just as comfortable as ever. No sign of sagging at all. Still best decision I've ever made in terms of beds.

Update 12/7/2015 - A whole year and four months in, still the best bed I've ever slept on. I am so glad I made this purchase.

I think the mattress has potential to be great and definitely a bargain for the money. The problem is the way that the mattress is packaged. Our previous memory foam mattress (another brand) came rolled up much like a roll of carpet. Upon opening the package it 'inflates' to proper levels. This mattress is folded in half and then rolled and crammed into a box. So after opening and allowing the mattress to inflate, a crease remains in the place where the mattress was folded as well as other areas being lumpy and uneven. The portion that did rise correctly did so rather quickly and appears like a great mattress. This was our second attempt- hoping the first was just defective. Unfortunately,both had to be returned and returning large items with amazon requires quite a bit of communication in addition to having to be home when the carrier service arrives. Save yourself some headache and keep looking.

It was thick enough, it didn't smell, it quickly expanded to its proper size after unrolling, and seems like a quality product. I noticed one odd thing though. I received the mattress before I received the frame I bought for it, which was this: Zinus 18 Inch Premium SmartBase 4 Extra Inches high for Under-bed Storage/Mattress Foundation/Platform Bed Frame/Box Spring Replacement/Strong/Sturdy/Quiet Noise-Free/No bed risers needed, Twin XL. So for one night I had to sleep on the mattress directly on the floor. It was great! Supportive but not too hard, cushy but not too soft. Then, the next day, the bed frame arrived. I put it together and put the mattress on it. Suddenly the mattress feels rock hard. Like it needs a couple inches of a soft mattress pad, or something. Weird! I don't want to sleep on the floor long-term, so putting it back where it was is out. Guess I'll have to invest in a soft pad to put on top.

So people who are complaining of how hard it is may be using stiff metal frames like the Zirius that don't bend or absorb shock from the body at all: try putting the mattress on wooden slats or a box spring and see if it is more comfortable that way.

I still think it is a good mattress, but it might have been useful to know that those metal bed frames are best with very soft mattresses before I bought my mattress. Hope that helps you make a better educated choice.

Ordered this mattress around Thanksgiving. It arrives on new years eve - probably because of Christmas holidays. It was a big improvement over my old spring pillow top mattress.

I fractured a vertebrae in February, and am convinced that this mattress facilitated my recovery without surgery.

I have had no issues in 6 months with the mattress:
No initial smell
No issues with overheating
Soft but supportive (I thin slightly firmer than Tempurpedic Cloud)
Quiet - spring mattress made some noise as it compressed and shifted
Motionless - both my partner and I tend to move while sleeping - this mattress transfers none of that motion to either of us. (the old spring mattress was horrible)

If any of my experience changes, I will update the review.

Didn't make me as hot and intolerable sweaty as a seperate foam topper I own. Super dense, nice and firm with give, squishy and luxurious. We use it for our 3 year old toddler, but I sleep in it periodically with him. My lower back sinks down a little which personally I couldn't do every night. But some people need more give than I prefer. I'm a 120 female. Fits our queen frame perfectly. Light enough to shift around by myself to put on sheets. Expanded almost emmediately to full size. Stinky for about a week. Let the fan blow on it and aerate the room it was in. Our son loves it and hasn't woken up once in the night since he's switched to this. Couldn't be happier with this! For this price, I would have gotten a horrible basic innerspring mattress that would have only lasted a year. This will last for a long time and it's SO comfortable for guests to use also.

We've had this mattress for over six months now and are very happy with the product. I've slept on it many times and when family came to visit they slept on it as well (not with me in it of course, because that would just be weird). Their comments are like mine in that it is very comfortable. The mattress conforms to your shape without giving too much and it resumes its shape once you get out of bed. I like that it doesn't seem to capture body heat either so it's comfortable to lay on whether the ambient temperature is hot or cool. My only complaint is that the smell took about five days to wear off and gave me a slight headache but now it doesn't smell like anything at all. If I had waited several days to use it then it probably wouldn't have affected me at all because I've been using it quite often since then and do not smell anything. We also have not had any sort of mold issues either.

So far so good. I think it's gonna take some getting use to coming from a coiled mattress that was probably 20yrs old. It didn't take long for the mattress to come to it's natural form after the 2nd day. The chemical odor is there and it's not unbearable but if you let it air out a few days and spray some febreeze it'll dissipate. Otherwise, the mattress is firm but soft once you sink into it. It does form to your body. I would recommend it for comfort and no more back and side pain from the traditional spring/coiled mattresses.

I am a 6' 250lb guy i bought this as a temporary mattress. It is currently sitting on a concrete floor with no mattress. I am very impressed, I have owned $4000 tempurpedic and this is almost as comfortable at a fraction of the price. I can't say how it will hold up yet i have had it for about a month. Great valie!

Best bed I ever owned. Never owned a tempurpedic or a $1000+ mattress but after seeing reviews and then buying and sleeping on this one...I could care less about tempurpedic. SUPER comfortable and ridiculously cheap. Great quality and seems very durable. As others have said, it is firm but soft enough to conform to your body. I have tried $600+ mattresses from Costco which other friends have bought and this feels just as comfortable, if not better (I have the 10" Queen size). Gets more and more comfortable the more you let it decompress to its intended state. Does smell a little funky but all new memory foam products do. It will go away with time. If you are on the fence about this one just go ahead and buy it. I trusted the reviews and you SHOULD believe the hype about this mattress...I sleep like a rock on this thing.

When we first opened up the box to this mattress and slept on it for a good few weeks, we thought it was great, it could have been because we were coming from a really uncomfortable mattress that we got rid of. In a matter of time we started to notice that maybe it was a little too firm? Or maybe too thin. Still not quite sure, we ordered the 8 inch I should have spent the extra money for a 12 inch maybe that would have made a difference. But regardless for the price, it is a good mattress and I'd probably buy the thicker one soon and maybe put this 8 inch in a sleeper sofa for when family comes to visit..

I recently purchased a pre owned RV and was not about to sleep on the old mattress that came with it. I looked at options for RV mattress and found out real quick that anything that has RV on the label will cost more than it should. So I turned to Amazon and found this one that not only had great reviews, it was an excellent price. This mattress was purchased to replace the one in the master bedroom in our 32 foot forest river Cherokee trailer RV. I did measure the base for the mattress and this one matched up perfectly. I was a bit concerned about how well it would do with the way the bed lifts up, bending the mattress in the middle for access to storage space, but it did great. When the mattress arrived it was folded in half , rolled up, and compressed in a box. It was a bit heavy, but with help I moved it onto the base of the bed and opened the box. I found that the mattress was contained in a plastic bag and once that was removed it began to take shape. I unrolled it and within minutes it was full and there was not evidence of it being compressed and folded. The foam mattress is covered with a durable permanent cover that I could have just put a sheet over, but I went ahead and purchased a mattress cover to keep it nice. The mattress is quite comfortable for both me and my husband. I weigh 155 pounds felt like it supported my weight well. The only problem I have found is how warm the memory foam gets, it is a known drawback to memory foam, so I knew what I was getting into buying it. I have read that adding a wool topper will help with slowing the heat transfer and keep it cooler. I liked it so much that I bought my daughter one for her camper too and she loves it just as much as I do.

I have recommended this bed to everyone I know. This is the first bed I've owned that I don't slowly and painfully get out of every morning...good bye aches and pains good bye restless nights hello energy and comfort. I love this bed and so does my husband. This was actually a surprise bday gift for him. At this price u can't go wrong.
It fully expanded in 48hrs although we slept on it 8hrs after opening it and it was fine. There is a smell but I wouldn't call it an order. It smells like New and foam. After a couple of days it disappears. You would have to be ultra ultra sensitive to smell for this to bother u.
All in all great buy AMAZING product!

Great mattress! Especially for the price. I would say it's worth much more than what it's priced at. On the medium/firm side. I've had firmer, but this gets the job done. You do slightly sink in but it's not much just enough to settle in (I weigh 160lbs). My back does feel much better, but still pain in my neck. This could be due to my pillow. Stop with every penny and 5 stars. I looked around and came to this out of some of the more expensive ones and I'm glad I did. Would buy again.

I received first mattress mid-August 2013. After a week it expanded to 8" at one end, almost 9" at the other, with a lump in the middle. It was supposed to be 12". Amazon had no problem shipping a replacement, so my husband and I managed to wrap the partially expanded mattress and have it picked up by UPS at our front door. Amazon paid the return shipping which must have been outrageous, given that the package was huge (54" x 35" by 25"). Replacement arrived beginning of September 2013, and it DID NOT expand either. In fact, one end was less than the other, and the middle had a hump, just like the fist mattress. Explanation I got from the manufacturer Zinus Inc. is that they ever hardly see this problem, and then ONLY IF the mattress has been rolled up a long time. It looks to me like Amazon has some duds in the warehouse and I personally would not "try" another one of these mattresses from them. (And we love Amazon Prime!)
I contacted the manufacturer both times. They referred me back to Amazon with the first defective mattress. After the second defective mattress, they fortunately took care of me directly. They asked me to donate the defective mattress to Goodwill and they sent me a free replacement, which arrived 3 days later. They also upgraded the model they sent me, although I am not sure whether that was done intentionally or not. Since I now have a different mattress than what I ordered from Amazon, I am not able to comment on the ultimate quality of this item. I am, however, happy with the replacement mattress that Zinus sent and happy to see a company that stands behind its products. I give Zinus Inc. 5 stars for their customer service.

I bought the 10" queen size for our guest room for an upcoming visit from family. I normally buy my mattresses from SAMs Club because of their no hassle return policy. However, the price on Amazon is so much better that I decided to buy it here this time.

FIRMNESS

At first, this mattress was very firm. However, having just bought one for ourselves, I know just how to soften it. For the first two weeks, every night, before bedtime, I "activated" my mattress by doing the happy dance on it. No,.....Im not being naughty, I actually walked around on the mattress (with socks on) and it softened it enough to conform well to my body. I know it sounds weird, but it works!! Even to this day, if I want my mattress softer, I just get up on it and walk around for about 30 seconds! Just be sure to wait 24 hours after opening the mattress, so that it has a chance to self inflate evenly. We have this mattress on a 16" steel platform frame that also serves as the box spring. I have become a huge fan of them due to additional storage space they create underneath.

ODOR:

The odor that people talk about smelled like a freshly painted room and left almost immediately.

COMFORT

I find this to be most comfortable with just me in the bed. My husband weighs more than me which creates a slope for me. This problem is not limited to this mattress, I have the same problem with my other mattresses. I did notice when we stayed at a hotel with a king size bed, I was able to move far enough away to be on a level laying field. So possibly the king size would eliminate that issue in this mattress as well.

OPENING

If you have kids, open this in front of them, because its just plain fun and magical to watch it grow! It grew to 9 1/2" within a few minutes of opening and a full 10" by the next day.

Im not sure how to rate this. If I were to rate it based on the great value for the price, I would give it five stars. Personally, Im thrilled with it. But is it a five star mattress? No, I would have to say that there are definitely better mattresses out there for a significantly higher price. So, Im giving it four stars and just saying, I am 100% pleased with no regrets. I feel my money was well spent.

I bought this mattress to replace a 20 year old spring mattress in the guest room and wasn't really expecting that much from it. I bought it expecting it to be better than a 20 year old spring mattress, but that's it.

This mattress is excellent! I have tried several mattresses at a Mattress One showroom, and this feels just as good as some of the most expensive brands that went for well over $1,000.

At less than $200 shipped, I cannot complain.

When I opened it, I could smell the "chemical smell" everyone is complaining about, but it was very weak and by bedtime 8 hours later I couldn't smell it at all. I didn't give it 48 hours to inflate, it seemed fully inflated 5 minutes after opening.

When sleeping on my side, I can feel the difference between a full memory foam mattress, and this one which only has 2" of memory foam, however, sleeping on my back feels amazing. And I haven't had any issues with it getting too hot.

Definitely worth every penny and I'm considering buying one for the master bed.

THE BEST MATTRESS I HAVE EVER OWNED!!!!! My boyfriend is a large man, he's over 6'2" and built like a lumberjack. Now when he gets out of bed in the morning or the middle of the night, I do not notice. I am an EMT, I have to be a light sleeper, hell, I was anyways, but him getting his manly butt out of bed doesn't move me in the slightest. I can sleep easier and SNORING HAS BEEN CUT DOWN 75%, no more sleeping next to mister freight train!!! woooo!!! WOULD DEF PURCHASE AGAIN!!

Let me just start by saying I have been sleeping on a $900 Simmons Beautyrest for 5 years and this bed puts my old one to shame.

After speaking to a man who used to work in a mattress warehouse, telling me that all mattresses are the same and that it is marketing and brand names that makes the money, I decided to put his claims to the test. I slept on it last night after waiting the recommended 48 hours (it was tempting) and I have to say this is the most comfortable thing I've slept on. The first thing I noticed when I woke up is that I was in the exact same position as when I went to sleep which is unheard of (no tossing or turning regaining comfort). Then the best part; I reached over to turn my alarm clock off and my entire back cracked down the spine (I'm assuming it was completely decompressed all night). Awesome investment.

Also, this crease other people are talking about from the mattress being folded oddly in the box; I don't have one so I don't know what they're talking about. Like I said I let mine rise and settle 48 hours before laying on it.

Attention college students this is the mattres for u. I was debating whether this was a good buynor not but im so glad i made he choice i just eeceived it today. It took 3 days which is good. The mattres feels so good, its so comfortable and surprisingly thick and comfy. Its gonna be my first night in it hopefully i like it im sure i will .

Love the fast shipping, packaging and instructions so straight forward. I bought these for my girls bunk bed, and I wish I can sleep with them. They are super comfy, ready for me in no time still had to wait to air it out from the funny smell but that's all gone after like half a day. The height it's just perfect actually had prepared mentally to be disappointed for some reason but I am impressed and very satisfied with this.

So.. I had been "researching" these memory foam mattresses for about 3 years. I went back and forth putting it off. Several months ago I came across this mattress.. I read nearly every review written (as I did on a couple of other brands) and I was intrigued that nearly all were positive (the others not so much) and how much detail was provided. Ultimately the reviews are what I based my purchase on so I feel it is only right to add to the list :) I recently turned 38 and I am the mother of now, 4 children. Money is most definitely a factor in all the decisions I make lol. I'm a nursing assistant- so working combined with my "active" home life (4 children and let's not forget my dog lol) you might say I put a lot of wear and tear on my body. For quite some time I found myself waking at all hours of the night/morning, hurting just to turn over and not feeling rested. The mattress set I currently had (Queen) wasn't all that old but my body (and mind) was to the point of craving comfort, literally! After much back and forth I decided wt'heck so I placed my order for a king! Yes.. king! The price (which of course would make anyone think, really? It has to be junk) was SO affordable that I was able to upgrade my size! My mattress arrived on time. As my boyfriend and I were (carefully) working it out of the box/package, the vacuum seal became broke during removal and within approximately 10 minutes my king size mattress was inflated! We pushed queen over and let the king lay flat and (almost) untouched until the next night. We took a couple of minutes to do a test stretch and immediately I was saying aloud, "Omg! I can't wait!" The next evening the platform frame arrived that I ordered as well, however, I didn't go with the one offered with the mattress. There was another that had more positive reviews so again, that was my reasoning behind thst purchase as well :) The moment was near and I must confess, I was definitely ready to put myself to bed early. My boyfriend and I put the platform together (simple), placed the mattress on top and dressed it with a 300 count sheet set also purchased from Amazon- $8.99/king set.. Ikr!? So I bought two, different colors because again what did I have to lose? Ok.. the moment is here. Time to lay down to validate the purchase. As I said earlier, I just turned 38. I'm approximately 5'7 and weigh in at 156lbs. My boyfriend just turned 37. Stands approximately 5'9 and weighs in at 220'ish. He is also a very HOT natured person (I'm the complete opposite) and that also worried me about purchasing a memory foam all together because most if not all are known for that. We have been sleeping on this mattress for nearly a week (tomorrow will mark it) and we love this bed! My boyfriend has not slept hot once! We both are waking less through the night/morning and we wake up feeling ready although neither of us want to leave the comfort of the bed lol. I find myself saying each time I get in the bed, just how very much I (my body and mind) love it :) I'm so very pleased with this purchase! Also, I am extremely thankful to each and everyone who has written a review on this mattress because again that is what I ultimately based my purchase on. I too, am paying it forward. I hope that by adding to that list of 130+ reviews, that it too will help someone with their decision. Oh.. and for those who are wondering where "Queen" went.. well she got passed down to my Dad :)

I bought this 2 months ago. Its very comfortable for sleeping. I only use it on the weekends. Other reviews complained that it was too firm, so I thought it would be a good fit for me (I like a firm mattress). It is almost TOO soft, so if you like a really soft mattress it would be fine. I like to sit in bed and work on my laptop and I can't with this because you sink into it too much (dont have this problem with the other foam mattresses we have).

Other reviews complain about the smell. We have other foam mattresses in the house, all of them had an odder that dissipated after a week or so. Its been over 2 MONTHS and it STILL SMELLS. I can smell it when I come down the hall to the room. I thought it just stood out to me because I was only their on weekends, but everyone says its still smells. Once I'm in bed I start to get used to it, but no other mattress smelled like this for so long. Will try to update in the future.
UPDATE: Smell faded by about the 4th month, way longer than it took for the other foam mattress we had (which was completely gone in under a month.) Updated to a 3 star rating. But still, for the long term might be better to spend the extra 100 for a better mattress.

TLDR; Its comfortable, but I wish I spent an extra hundred and got a good mattress. This was a good option for me because I only need it short term.

EDIT: 1 year later, only sleep on in on weekends, and there is a dent in the bed where I sleep. I am a healthy weight. DO NOT BUY.

I spent a solid 10 hours looking for a mattress in this price range. As my research indicated, competition is fierce in this low price range, which is why I feel obligated to report my very positive experience. There are a lot of well-reviewed products available. I can't say exactly WHY I made this choice, it was essentially an eeny meeny miny moe game. We didn't know whether we wanted a firm, medium, or soft. We opted for a thinner mattress based reports that they are generally cooler, and we live in AZ. Feeling like the mattress is giving back heat was the least desired trait and this in this aspect we have no complaints.

Myself and the wife have slept on this mattress for a couple months and are very pleased. Given the improvement over our previous king inner-spring with 2" memory foam topper, I don't think that spending any more money could be justified. Previously, we had both been awaking with increasing back discomfort. I was waking up what seemed like every hour due to discomfort and switching positions.

Shipping and receipt were just as expected. It did have a scent, but nothing I did not expect. The warranty period isn't as long as pricier "brands", but given my satisfaction and affordibility I would be willing to buy another upon expiration if there were an issue. Great value. I will update if there are any negatives since it has been only a couple months.

So excited to sleep on this mattress "cloud!" Unfolded from packaging and quickly took form, very faint chemical smell but not nearly as bad as other described. I've waited a long time to upgrade from a queen to a cal King and this mattress was so worth the wait. Not bad price at all either. Love Amazon!

I bought this because of the positive customer reviews so I felt I owed it to the next guy that may be wondering if this mattress is worth it. Absolutely. Most reviews said it took about a half a day for the mattress to raise into shape. Mine took about five minutes. I put it on the existing box springs I had from the old bed and we slept on it that night. Zero smell to this mattress. We got it about a week ago and my wife and I could not be happier. Yesterday she told me that I have not snored since we got the new mattress. This may not seem like much, but I have snored for 40 years and I have sleep apnea and sometimes stop breathing for enough time to scare the crap out of my wife. Would I recommend this mattress? I already have. My sister just ordered one.

The Sleep Master Ultima Comfort Mattress is a hybrid foam mattress than combines various layers of foam to provide support and comfort.

We recently upgraded the kids rooms from full to queen beds and in our exhaustive search for mattresses Costco seemed a logical choice, but since the mattresses were twice as expensive, we decided to take a chance on Amazon and we could not have been happier.

We needed a mattress to work with an adjustable bed with a massage function and it was time critical. We estimated that the 8" would contort a little better with the adjustable bed, but Zinus was (and still is!) out of the 8" mattress, so we decided on the 10". After installing the mattress, we found that we were right - though the 10" is very comfortable and works well just fine with the adjustable bed, it resists the folding and the massage function is more vibration that massaging.

The Ultima mattress came in a rectangular 18" x 18" x 42" box weighing about 65 lbs. This is very convenient to move it the final room especially if it is up stairs. Use a scissor with care to open the tightly wrapped mattress. The mattress opens up and instantly gets to about 75% of its size within a few minutes. It takes about 2 days to get to full thickness - which is less noticeable in the 10" or 12" mattress than the 6" or 8" mattress

The Ultima mattress is all foam and does not have a wire-frame edge support. The multiple foam layers design is a very good solution for comfort and support.The bottom is 5" high density support foam and the top is 3" memory foam with 2" comfort foam sandwiched between the two layers. All these layers are wrapped in a cool, comfortable jacquard cover.

The Ultima mattress is very comfortable to sleep on. It is cool and provides good support to anyone about 200 lbs. Since this mattress does not have a a rigid wire-frame edge support, the foam starts to give at the edges beyond that weight limit. I have tried and disliked 100% memory foam mattresses because I was unable to move/turn and it made me feel stuck and very uneasy. But this Ultima mattresses 3" memory foam allows me to move free with all the memory foam benefits.

Recommended.

Pros:
* Excellent price point
* Supports combined weight up to 450
* No foundation required
* Multiple layers of different foams are designed to provide support and comfort
* Medium Firm mattress provide good back support
* Memory foam layer does not make you immovable in the bed
* Lack of a rigid wire frame makes this great for adjustable beds
* Package is easy to move between rooms and carrying up stairs
* Low foam odor disappears within a few hours

Cons:
* Returning after un-compressing is difficult if not impossible.

the product comes all rolled up .. then you have to let it air out. It was great we had a spare bedroom to let it air for 5 days.. couldn't sleep on it just too harsh plastic-oily smell.. the mattress is not firm.. If you sit or lay on the very side of it .. it really compresses. but in the middle it supports well.. ... does not trap heat against the body as others have stated

I bought this for my daughter. Honestly, I am stunned how great this is. I have owned a TermpurPedic for many years and swear by them but it was $2500. I couldn't afford that now for my daughter but her mattress sucked. This thing is pretty awesome, she loves it and I could definitely sleep on it. It feels pretty well just like my 5 yr old Tempurpedic - it's just right, not too soft, not too firm. As far as smell, there isn't any. I am pretty sensitive to smells (we use almost no scented products at all and what little we do are all natural plant derived - i hate chemical smells). I think it smelled a tiny bit at first but I just left it sitting out in the den for a day or two and then it was fine. I can't believe they crammed this thing into the (still rather large) box. It was vacuum sealed and anyway, believe me this thing is like a life raft - you pop it open and it uh, grows in size right before your eyes. It was really cool. I don't know if it will last years, of course, but I will update a year or two from now and we'll see.

Been sleeping on this mattress for about a week and a half or so..

So anyone looking to buy this mattress can pretty much ignore all of the really bad reviews. I was hesitant to buy at first but I went with it anyway, it's only 200 bucks right? Here are some counters to negative claims made about this mattress

*Strong chemical odor
This mattress definitely has a strong odor, you'll be knocked over by it the minute you open up the vacuum sealed bag.. Do as the manufacturer suggest and let the mattress sit out for at least 48 hours. I let mine sit in a spare room with the windows open/fan on for a few days. I don't notice any smell coming from it since I have brought it in my room and added sheets/comforter.

*Mattress is too firm
I think half of the problem here is people are confused about what memory foam is all about. Many people are basing their claim on their experiences with memory foam toppers or pillows. Obviously, there's far more mass involved with a mattress, so you're not going to get that pillow-like feeling. Note that while this mattress is firm it perfectly contours to your body, eliminating pressure points. If you're really concerned about how soft it is, add a topper.

*Mattress gave out after X amount of time
In my opinion.. If this mattress lasts me for more than 18 months I'll be more than happy. The thing was 200 dollars, brand new. I don't see the argument here. Top of the line mattress cost thousands of dollars.

After typing that last one I feel like pretty much any other grievance can be countered with just that.. it's 200 bucks!

I am so happy with this purchase. Our bed had been giving us problems, so we looked into buying a new memory foam bed. I hate buying anything in person these days so a bed I could get delivered to my home was a no brainer! It arrived in two days, and we immediately opened it up to let it decompress for 24 hours. After that it was good to go! It is the same quality as our $2000 memory foam bed we purchased 5 years ago from the furniture store. Heck, even if I have to buy a new one of these every 2 years I'll still come out ahead. You really can't beat the price.

I've had this mattress for about a month now and I couldn't be happier. I was really worried about there being a strong smell to it after reading other reviews but after a couple days the smell was gone. Now, I sleep better than I have in years! It was definitely worth the money.

I got this for my mother, who is wheelchair bound and has Parkinson's disease. She has a lot of hip, knee and back pain. She has been using an adjustable hospital bed at home, and the mattress and gel overlay were awful, no matter what you did to it. We ordered this mattress because it was a very reasonable price. (We got the twin XL.)

Last night was the first night she used it. She slept 8 hours straight, and woke up without any back pain, which hasn't happened in probably 20 years. Her bed is adjustable, so that was a big part of it, as well.

The mattress has a nice softness to it, but it's much denser than I would have thought, which is good. She has difficulty getting in and out of bed, and mattresses that are too soft make it a challenge for her.

I opened the box before I went to work in the morning and laid it out on my bed during all day. It didn't any time at all to assume a normal position. I set it up when I got home from work. We did not notice any odor from the mattress once we took the plastic away from it.

Something I didn't notice in the product description (which I probably just missed) is that the mattress has a removable lining to it. The cover zips off so it can be washed. This is a nice feature.
I hope this mattress holds up for a long time, because it's great for my mother!

Update: After using the bed every night for 10 months, it still retains its original shape and density. It's just as comfortable as the first night she used it.

We bought this memory foam mattress when we were looking for a replacement for an old spring mattress we were using. Honestly, we didn't expect much for the price but boy were we wrong! This is one of the most comfortable mattresses we have ever slept on!

Both my wife and I have back pain due to car accidents so it is really hard for us to get comfortable at night. As a result we used to keep each other awake tossing and turning, but not anymore! In fact, I can hardly feel her move on her side of the bed when I'm awake and when I'm asleep her movements don't wake me like they used to.

The memory foam is very soft and forms very nicely to my body. The mattress does get a little hot at times but not overwhelmingly so. It fits perfectly on our queen frame and is very durable.

When it arrived at our door we didn't know what to expect because it was in a box that was tall and thin, but when we unboxed it we saw the mattress immediately begin to take shape and we were able to sleep on it the very same night (with a little bit of Febreeze sprayed on it to knock down the odor).

I would highly recommend this memory foam mattress to anyone who is looking for a mattress replacement or for anyone who has back problems and has a hard time getting to sleep at night. This mattress has been a miracle worker for me!

I was hoping for an experience more like my pillows or mattress pad, but thicker, but not so soft that it hurts my back. This is not it.

This mattress is so firm, that I got up and looked at flipping it over - thinking maybe I was sleeping on the wrong side. From a posture alignment perspective, it is good. My spine is aligned when I sleep on my side. I don't have back pain.

But, it feels like I am sleeping one of those thin mats on the floor. The mattress only gives at the pressure points. I hardly sink in the mattress at all. And, I am unable to sleep on my stomach. It is either really uncomfortable or causes back pain. I've been too exhausted to figure out if I am sleeping on my back.

Interestingly, it does not slip. I have it on a metal platform frame and it seems to be quite firmly in place.

I let it expand for 48h before laying on it. No smell.

As a tip, don't open the package to make it easier to drag upstairs. It expands on the way up and gets quite heavy very fast.

My biggest issue with it is that it is so firm. The softness is only the surface. If you brush your arms across it, it feels soft. But, when you lay on it, it's slightly more cushioned than sleeping on the floor.

Update: Two weeks later, the mattress has softened up. I can now sleep on my side, back,mand stomach without back pain. I am docking a point because it feels like I am making an indention on a smooth surface and and another star as it does not feel luxuriously comfortable but it does not interfere with my sleep. I am now buying a topper and a plush pad to add a few inches of softness so that I will hopefully retain back support but add that luxurious feeling. I guess it is fair to expect that a mattress purchased online will require some adjustment, but I do wonder if it would have been cheaper to have chosen a different one in the first place.

If you have purchased this mattress and find it to be too firm or are looking for back support and plan to buy this one, my recommendation is to give it two weeks and to sleep on your side during this adjustment period. If you still find it to be too firm, options are to return it (yes apparently this can be arranged) or add additional layers. As one last comment, I bought the 8 inch, so I can add additional layers and still fit within standard fitted sheets. You may also want to consider this as well when deciding how think you want to go.

Update #2 - It has now been a little over two weeks since the mattress arrived. I became happier with it as it became softer, but wanted a truly 5-Star sleep experience. So, I purchased the Sleep Master Gel Memory Foam 2 Inch Topper, Queen. It turns out that this supportive mattress paired with that softt topper was a perfect combination. Every inch of my body is cradled in a cushion that gives at pressure points and supports my weight there and everywhere else. I love it!

Update #3. The mattress has grooves where I sleep. Laying on it causes me back pain. I figured out that this is due to no lumbar support. There is a gap between my back and the mattesss when I sleep on my back. When I lie on my stomach my back caves forward. The next day, I have to stop and stretch my back. If I drop something, I pick it up slowly and carefully as my back is stiff and creaky. To combat this, I am now laying on the other side, but back to sleeping only on my side - as I did originally. And, now that I have figured out that I can lay on the sofa with no problems, this confirms that the problem is the foam mattress and not me.

Update #4. I ended up with terrible back pain after using this mattress. By the time I resorted to trying to sleep sideways across the bed or curling up so my spine would realign, I figured out that this was not going to work out. Fortunately, this was within 30 days, and I was able to return the mattress for a full refund. But, the reality is, any bed may need some help. So, I just wanted to share what I have learned.

How to Choose a Bed

#1. Ignore reviews of anyone who has had a mattress for less than two or three weeks; the mattress is still changing. New reviewers are just excited about opening up the package and sleeping on a real bed. You want to know how well the bed sleeps after its break in period.

#2 - Go through some of the online wizards and articles on how to choose a bed depending on whether you are a back, side, or stomach sleeper. Note that you do not have to go very, very firm if you have a bad back. Back care is all about sping alignment. Soft and firm cushions are all about preference. I learned that Imlike a plush feel on top of a bed with responsive spine alignment. I sleep on my back, stomach, and side. And, I want my spine to be aligned even though I have a curvy hips and butt. I want to have a bed soft enough but firm enough to cushion my breasts without my back feeling like it is caving in. I started with an innerspring mattress with a plush topper. The innerspring is responsive so that I am not waiting for it to reinflate when I turn over. The cushions feel luxurious.

#3. Do not buy bargain cheap or top of the line expecting it to be what you need; a bare minimum is that a bed should support and align your spine and beyond that it is all about cushions and toppers - which you layer on yourself - so leave room in the budget for this.

#4 - Do not assume that you will like memory foam mattresses. If you have never tried one, go to the Mattress Firm around the corner and lay on some beds. But, go in there to learn how the different types of beds feel, particularly the support. DON'T BUY from them for heavens sake... unless you want to spent $3,000 for a $1,200 mattress. If you want to go local, I found a mattress that felt like a $1,200 hybrid for $600 after discounts at Sears.

How I Fixed Back Pain Due to Body Impressions and Sinking too far in.

I tried many things. In the end, a good end is all about support first and cushion second. If you are sinking in too far or jackknifing or hammocking, then it means that you have inadequate support - those are the hard layers below. It makes the mattress counteract your weight by pushing up against you and you press down in it. What I did not get is that all the layers respond, not just the top ones. So, the support below the mattress is just as important as the cushy layers above. The job of the top layers above is just to counteract pressure points, so you do not ferl like you are laying on the floor. The job of the bottom layers and boxspring/foundation, is to keep the mattress feeling firm and to keep it from sagging. That said, I fixed a sagging mattress, sinking in, and back pain by putting a smooth, hard layer underneath the mattress - no gaps, slats, or holes. A heavy duty cardboard moving box covered by a blanket is a temporary fix. Plywood or a good old fashioned box spring are other options. Point is, try this first.

Got it for my son (4), he is sleeping alot better

I was a bit skeptical to buy this mattress being that I have never ordered a mattress online before and I am very picky about my bed. But I must say I ordered the 10 short queen this was amazing from start to finish. The bed is not to soft nor too hard, It forms to my body and I don't have to keep turning throughout the night to get rid of sore spots, I could not believe how small it was when it came in and how fast it expanded and held up, and there is no weird smell that I have herd of on other beds. I have had it now for 48 hours and at 36 hours I had measured it at 9 inches in height (which is way more then needed) and it says clearly it takes 72 hours to fully expand, I am sure it will but I will update with pictures. I pared it with a Zinus 14 Inch SmartBase Mattress Foundation Full Size to fit the short queen and I must say they work great together.

 This is a good mattress! It's very comfortable, my daughter picked it over her older traditional mattress which she had for many years and loved. It doesn't have a spring to it like her older mattress, but overall she found it to be more comfortable.

5 stars :)

Shipping took forever, so if you can afford it go with the paid option. Bed came packaged awesomely. Took no time at all to gain size and the smell was minimal. I ordered the firm and so far it seems perfect. Will update my review after a few weeks of sleeping.

*Updated review* 2/16
Not at all what I expected. At first it seems comfy but after sinking into the mattress the back pain begins. Haven't slept a peaceful night since yet. This firmness is probably best for back sleepers. I'm a side sleeper coming from a mattress that was too soft so....

*Update 3/5/16
Even though the bed wasn't right for me I can't find any fault in it. I thought I needed a firm but it was too hard. The company worked with me and honored my return promptly and for that I'm giving five stars. I would definitely buy again now that I know a little more about the feel of the mattress.

Before this I had a pillow top queen mattress and after three or four years the pillow top mattress became more like Lump Mountain, Pretty sure it's the cause of my tendinitis I have on one shoulder now. I checked out the reviews on this memory foam mattress of course the whole mattress is not memory foam just the top layer however it laid out pretty good on my queen bed and I have no box spring underneath it, just laying straight on my frame. Works perfectly, the evenness of this memory foam is pretty good, my shoulder pains are going away as the relief is a whole lot better. I did not receive a discount or a free mattress for this review. I am really glad I purchase this memory foam. Yes it does have a certain smell to it but last probably about a day. I wouldn't put any sheets on it right away, just let it air out for a day or two first then you should be ok sleep well.

At first, this seemed like an amazingly comfortable deal. Problems showed up after a while though. After 3 months, the mattress sagged several inches in the place that I sleep- to the point that I was waking up every morning with back pain. I moved where I sleep and even rotated the bed and after 18 months, there was no place left for me to sleep without pain. It's incredible how important a good night's sleep is on quality of life.

"No worries", I thought - "This mattress has a 10 year warranty". And, it surely wasn't fulfilling it's intended purpose, and to no fault of mine. So, I contacted customer support. They had me run through a bunch of hoops taking pictures at this angle and that. I could prove that the mattress sagged over 3 inches when I lay on it, and that my spine was in a V shape when I'm laying on it, but that didn't make the warranty criteria. The mattress has to sag at least 1.5 inches without any pressure on it. Who has ever seen such a mattress - especially one made out of an expanding foam?! So, here I am with a worthless, pain-inducing mattress and the "Worry free 10 year limited warranty" doesn't cover it. Seems like something worth worrying about to me.

I'm a 260 lb guy- your results may vary if you're significantly lighter.

Great mattress - very comfortable. Arrived quickly and was easy to carry upstairs on my own. Inflated and was ready to use within an hour, though it needed a couple days to air out to get rid of the packaging smell. Highly recommend the mattress, but plan on opening some windows, burning some candles, and not putting bed clothes on it for a couple days after it arrives.

Super comfortable! Although it does take several days to air out the smell (the paperwork a says its normal and safe however it was very strong) so make sure you have it in an area that has good ventilation.
My son loves it but says "it doesn't jump" so it's perfect to stop the bed jumping

This is our third Zinus memory foam mattress; we purchased the Twin 10" for our oldest son because he complained his old mattress was bugging him.

He normally has a terrible time falling asleep and staying asleep, but after setting this up on his bunk, he drifts right off to sleep with no waking during the night. He's told us he no longer remembers falling asleep, just that he's more comfortable than he's ever been.

I had to take off a star for just one reason: it's slightly wider than a standard twin mattress, so it overhangs slightly and doesn't rest fully in the bunk, but not enough to be a danger, just kind of tilted.

I purchased this mattress a few years about and my son loves it!! Since it was such a great mattress I ordered another for my youngest teenager and have been super disappointed. When we received it, we let it do it's thing and it never decompressed fully. Some points are 10" and some 11" in height. I did get a replacement and that one never decompressed fully either. Some spots are 9" in height. I could deal with the mattress not being even or fully 12" but it's the memory foam that I am most disappointed with. There is no memory foam response with the mattress at all. Feels like a cheap regular foam topper. I purchased this again because of the first great experience, but something has changed. New manufacturer?? Or two defective mattresses?? Not really sure, but would not purchase again.

Really upset with this mattress. I specifically ordered the same one my friend had, yet mine is 10 x softer than the one I slept on. I have attempted everything from consistently rotating/ flipping, but it is awful. I can't sleep in one area for more than a few nights otherwise they is a huge dip in that area and my back becomes caved in during the night. I am the only person that sleeps in it and I only weight 145 lb. It has now gotten to the point where I am looking for a new mattress or possibly getting a thick mattress pad to fix the caving in.

This mattress is literally life changing, my husband and I both have bad back problems and this mattress has changed that. I’m definitely ordering mattresses from Zinus again. There was only a few bad things about this is that shipping took forever, FedEx absolutely sucks and the mattress had a little bit of a smell. But other than that 10/10 recommend this mattress.

I purchased this mattress for my guest room. When we have family for gatherings overnight everybody wants the room with that mattress. They have threatened to take it home with them. Actually, I just got a text from one person requesting order info for the mattress so they can order they own. Everybody loves it!

My back pain is really bad from the mattress.. my dad asked about it and I would never recommend this mattress ever.. my back hurts.. my boyfriend came last night and he could not stand my bed at all.. I’d rather sleep on the floor than having this mattress.

Wake up and back hurts most the time. Thought this softer mattress would be better for side sleeping, but it turns out it is very bad. My back near my hips hurts almost every night I end up back side sleeping. Now, the SHOULDERS don't hurt, the mattress allows the shoulders to sink in, but then it allows the hips to sink in - WAY too far - and then you end up with zero support and hip issues. Do NOT recommend this for a side sleeper.

Have had my mattress for a little less than 2 years. I have been experiencing excruciating back and neck pain the last 2 months. I have been having terribly night sleep to the point I cannot sleep on this mattress anymore. Do not recommend.

Very comfortable mattress for a great price. Got this bed for our guest room, but truthfully think about switching it to the master bedroom it’s that comfortable.

I bought the 8 inch. I slept on my friends 10 inch and it was a softer than I like. I enjoy the 8 inch much better, tiny bit soft yet firm below. Great price and slept like a baby!!!

I love this mattress. I sleep like a baby!

Bought the king size mattress for my parents who are particularly finicky about comfort due to backaches and they LOVE this product! highly recommend it!

Very comfy! Pretty impressed considering the price actually. Been sleeping on it for maybe two months now and no complaints at all. I'm a side and stomach sleeper. Works for me!

6” mattress perfect for bunk beds!

this mattress will make you never want to leave your bed its so relaxing to tight muscle I can see a very big difference from the hybrid firm icolie mattress I totally regret going back to the spring mattress and my back sees the difference also Zinus the best easy to order and set up hassle free service its worth ever dollar i really miss this mattress, Queen 12' its like sleeping on all pillows my arthritis was happy it felt expensive i recommend this to a few friends who are extremely happy

Most comfortable mattress I have ever owned. It’s like a mystery mattress because it’s so amazingly comfy!

Its amazing. At first it take a minute to adjust but overall i love it.

My dad got me this bed when I moved into my first place on my own. I was so thankful it really didn’t matter what it was as long as I had a bed since I didn’t have anything starting over. After three months I wake up with the worst back pain I have the 8inch green tea memory foam mattress. And I wish I said I loved it. I do on the other hand love the way it looks in my room. ;). Sure wish I had a way to correct this. I have a terrible back after a c-section.

Perfect in every way. SO inexpensive. NO smell. Expanded immediately after unpacking. Bought my first Zinus platform bed and mattress on Amazon, was curious about Zinus and ended up going to the website. Bought another mattress, bed, and sofa. Now when anyone mentions buying a bed or sofa I'm all obnoxious telling them they HAVE to go to ZINUS first. I even spell it to them.

This is the worst bed I've ever slept on. It feels like I'm just sleeping on the floor. There's no sinking in like other memory foam mattresses. It's too firm and it doesn't relieve any pressure. I have to stretch every morning to relieve my joints of the stiffness this mattress causes. Don't trust this brand.

This bed is absolutely amazing. I sink right into it and have been getting the best sleep of my life!

I wish it were just a tad more firm, but this is a great mattress overall if you're a fan of memory foam. I don't feel that it gets too hot at all, and I find myself less sore in the morning

Our back hurt soooo bad from this mattress. Horrible!

Get this mattress. My husband has back issues so needs good support. I sleep on my side most of the time so I wanted a bed soft enough to not give me shoulder pain. Somehow this mattress is perfect for both of us. Every time we go on a trip we dream of getting home to our bed. So convenient, so easy, so right.

This bed has turned out to be a good fit for me and my boyfriend who are both side or stomach sleepers depend on the night. It did take a week to get used to the firmness of the mattress but well worth the wait

I’m a chronic side sleeper and was told this was made for that/pressure relief... wrong this thing is as hard as a rock, I wake up every morning with super tight/stiff shoulders and can’t even lay out flat without some serious adjustment for support... maybe they have other sleepers that do what they say but the pressure relief ones aren’t actually that, but rather seem to cause more pain.

This mattress is one of my best purchases I’ve made in my life. I’m not going to lie I was hesitant to buy because of such a great price and the saying “you get what you pay for” and the concerns about fiberglass, but I’ve never been happier with my decision. The first week or so doesn’t feel the best because I feel like it has to really stretch out but after that I’m obsessed. I feel like I can go to sleep easier instead of tossing and turning. I sleep throughout the night without constantly waking up, which is crazy for me. I have no complaints about it.

I love this mattress, i had bought a Casper and it was firm and had to return it. I'm 150 lb guy and got the 10inch memory foam, my sister had bought the same. Very Couldn't be happier.

We are disappointed because after purchasing three mattresses from you (two twin and one full-size), one of the twin mattresses has started to dip and sag in the middle.

The Pressure Relief Green Tea Memory Foam Mattress is awesome. It's close to 2 years and still holding up in good shape.

At first, I was nervous about purchasing a mattress online. Then I laid on it and all my anxieties were put to rest. I bought a full sized bed and it fits me and two large dogs. I can't get the lab off. He's in love.

Mattress never inflated completely, it also is not thick enough to just place on a platform bed frame as it describes. (I ordered the 8 inch one) You can definitely feel the frame through the mattress. Contacted the company about a warranty which was simple however they would not let me exchange it out for a thicker one (of course I would pay the price difference). Considering these are always sold out it’s very inconvenient and will probably end up having to go to a different company unfortunate for them.

I ordered the pressure relief mattress because I have chronic pain and this mattress came up when I answered the "find your mattress" questionnaire. However, this mattress does not work out for me. I wake up in more pain than when I went to sleep. This was the second attempt at finding the right mattress through Zinus. I have found out that I have to stay away from anything that says "pressure relief", because it does not give relief. Unfortunately, it has been more than 100 days and I am unable to return it.

Purchased queen 8” but my bed never rose to 8” after one week. Disappointed, bc thats how ya feel when someone CHEATS AND STEAL FROM U. My bed remains 6.5”. I REGRET IT, I WILL CASPER NEXT ORDER! The bed I got was manufactured in 2018. Wow! Two years being decompressed then u give me trash! Temper-pedic makes foam when u order it. Beware! Don’t purchase Zinus! Farewell, Hard working Single Mom

Bought one it didn't inflate couldn't get back in the box to take back to the store so I'm out 200.00 dollars.

I loved this mattress for 3 years and then the springs began to fail badly in one specific area. This is an obvious manufacturer defect and Zinus refused to honor their warranty because the foam is not failing even though this is a hybrid mattress with springs. After a dozen emails and a dozen pictures with the warranty department showing the failure they just kept asking for more photos of the same thing I had already provided several photos of. This was initially a great mattress, but unfortunately this is a company that does not stand behind their product at all.

you buy this product I wish you all the best. I received a defective mattress and I have Been fighting for months to get them to honour their warranty. I have received nothing but run a rounds. I suggest you do your homework, begin with the Better Business Bureau. They have a D- rating in a US state and are not even a member in Canada.I tried in good faith and have been runaround and when that didn't work they just blocked the calls. It's a shame Amazon supports this company

mattress started falling apart in under 8 months, made claim and explained why I didn't want a replacement of a mattress that will not last 8 months zinus sent one anyway with out my consent I refused the delivery, now thay have my money, after weeks of emails back and forth the last I received (paraphrased) Thank you for showing us the faulty materials and refuting every one of our claim denials with fact we will still not provide a refund. Mattress and business practices are garbage. STAY AWAY!

I've had my bed for 4 years and it's starting to flatten and sag ,I called about the warranty and was told they couldn't approve it because it's not on a base( it's on a frame that doesn't need a base,plus states it can be used with or without). They just have the warranty for show don't waste your money.
