Signature Sleep

Signature Sleep provides a direct to consumer mattress through its online and retail partners. You can find their products on popular sites like Amazon, Walmart, Overstock, and more. Their claim to fame is affordability with many larger size mattresses selling for under $500. If you are on a really tight budget and need something temporary, you may be intrigued by this brand, but there have been reports about quality issues and durability problems with some of these mattresses.

Zinus

Zinus has been in the furniture game since 1979, selling extremely affordable furniture. When it comes to their mattresses, they put a focus on trend-setting comfort materials like green tea infused memory foam and other bio-foams. They make three different mattress lines -- iCoil® hybrid, traditional spring, and memory foam (including their popular Green Tea Memory Foam mattresses). All of these are extremely low-cost, which can be a big draw with customers, though there have been some recent disagreements about degrading comfort.

Based on our aggregated reviews and our scoring method, we recommend Zinus in this match up!

Signature Sleep's Owner Satisfaction

Not all sleepers like these mattresses. Some sleepers were unhappy with the comfort, but others were really pleased. One of these mattresses may be great for you, but it makes it harder to predict. Continue reading below to learn if one of these mattresses will work for you.


Signature Sleep's Supportiveness

Having the proper supportive structure of a mattress is essential to its feel and whether it is beneficial for the back and spine. According to most reviewers and customers, these mattresses are good at supporting sleepers. This means that these mattresses should make you rest easy!

Edge Support
Most sleepers say they are happy with the edge support of these mattresses. This means that you can be comfortable sitting on the side of the bed and the mattress will feel supportive.

Bowling Ball & Density Tests
The bowling ball test is popular for measuring firmness. Without many complaints or issues, these mattresses have a consistent surface, which is great for customers that need extra security in buying.


Signature Sleep's Durability

Everyone wants to find a mattress that will last over a decade, and when our mattress is painful after only a few months, we feel cheated. That said, finding a mattress that is comfortable and durable is really hard these days. With more products available than ever, some brands are sacrificing quality. In terms of these mattresses, some sleepers report durability concerns. Not all customers will experience durability issues, but make sure to review the return and warranty policies before buying.

Zinus's Owner Satisfaction

Some customers felt very comfortable with their new mattress, but others couldn't get comfy. Despite those that love these mattresses, these mattresses have lower than average customer satisfaction. Look on below for more information if this mattress will work for you.


Zinus's Supportiveness

These mattresses are good supporters vs many other competitors. They do a great job aligning the spine and help sleepers feel comfort. Customers feel that these mattresses offer support and and don't mention initial issues with loss of resiliency.

Edge Support
Edge support is important for those that like to sit on the side of the mattress and are looking for even support. These mattresses offer that supportive balance towards the sides.

Bowling Ball & Density Tests
The bowling ball test helps measure the firmness and even support of a mattress. These mattresses do well keeping things even and resilient throughout the mattress.


Zinus's Durability

A mattress that has good longevity can save you thousands. But as companies compete for profits, everything from clothes to mattresses wears out faster. These mattresses have mixed reviews when it comes to durability. Each bed is different so it may last years for you, but others may not be so lucky. If you are considering, make sure to read more before buying.

You Get What You Pay...Cheap is Cheap.
BUYER BEWARE! The reviews on this are highly inaccurate. I bought mine in the middle of April and am going to be very honest...this mattress does NOT live up to the hype. For the money, it's worth the buy but for the quality it's worth the wait if using all the time.

Good:
Mattress was delivered timely in a box and easily set itself up after we "opened" it.
Mattress was good to sleep on nightly for about 3 months.
Mattress is durable and handles dogs.

Bad:
Mattress had a funny smell(to be expected) for about 72 hours.
Mattress started to "lose" it's firmness and had a sinking feeling upon laying on it after 3 months.
Mattress is now the cause of many aches and pains.

Do buy this if you need a quest room mattress. Do NOT buy this if you plan on sleeping on it every night and need something semi-firm. If you like the soft sinking feeling, this could be a great buy. However, if you're like me and have lower back issues, do not buy this. As with anything, you pay for what you get. I didn't expect much out of a $300 mattress and I didn't get much. I gave it three stars because it's only worth three stars. This is NOT a 5 star buy unless you just need a guest room mattress.

The photo that I've attached is me pressing down with an outstretched hand and I am crouching so that none of my body weight is on top of it. The compression resulting is deep and shows the mattress is cheap.

it's not like what it says 3 layers of foam
there is only two layers of the foam, one is the white memory about 1", then it's the yellow regular foam, about 5", it's not like what it says 3 layers of foam, you can buy these two layers in Walmart with a much cheaper price.

Firm and comfortable
This is a really comfortable mattress! We bought the twin size for our 5-year-old, but I'm thinking of getting a big one for us too. It did need to be aired out before use: the instructions recommended 48 hours and that was sufficient.

Memory Foam lover?? - Just go for it!
I was looking for a Memory foam "Queen" mattress around 8-10 inches thick for under $300 and after a week's research, zeroed in on this one based on the following:

1. Price - I don't think you'll find this kind of mattress with a better price anywhere on the internet.

2. Comfort - Like it is mentioned in the description, it is not too firm, and not too soft - Just the way I wanted. I have been using it for a week now and I can say it is quite exceptional. I can't say it is the best mattress you can ever find, but for this price, I think I can.

3. Shipping - Free Shipping and the mattress is packed in a hassle-free, easy to carry cylindrical bag (40 lb)

4. Odor - Unlike some have mentioned in their reviews, I didn't have a problem with the prolonged odor. There was a little "mattressy odor", but just for about 5 - 10 minutes.

Also, it just took 10-15 minutes for my mattress to restore to its original size. And I'm glad I bought it.

Bottom line - Awesome product!! Highly recommend it to people who like to sleep like a baby!

This bed is absolutely fantastic. My boyfriend immediately asked me where he could ...
This bed is absolutely fantastic. My boyfriend immediately asked me where he could get one and was shocked that it only cost me 200 bucks. I've been recommending it to everyone. Minus one star for the packaging. It was so difficult for me to get out of the bag that I almost threw the darn thing through a wall. Other than that I am so extremely pleased with the quality and comfort of this mattress!

Update: I've been sleeping on this mattress for a few months now. About three months ago I woke up with a little back pain. It has been steadily getting worst and I now can't even lean forward without it hurting. I've had to spend a lot of money to get treatment and my doctor says this mattress is likely the cause. It's definitely a comfortable mattress, but it really doesn't give any support. I still like the mattress and will try adding a firm mattress topper to see if that fixes it. Minus one more star...

BEST MATTRESS EVER!!
This has been by far the best mattress I've bought. Came 1 day early perfectly wrapped and boxed well , i opened it and laid it flat like it said and the bed came to FAST a little over 12 inches more like 13 inches (No complaints) the mattress feels great firm but yet soft with all my curves. It has a slight smell to it , not a bad smell just like a mix of plastic and hair Spray lol but again not a bad smell. All that matters is the mattress is awesome and the price is great!!! I am currently laying on it as I type. Tonight will be my 1st night sleeping on it so I will give an updated feed back in 2 days.. I know i will have nothing negative to say . The best feels GREAT.

Not durable
Using it for almost 8 month. The middle part became soft and don't have a strong support for my body. The edge part is still firm because it's barely used. Won't choose memory foam mattress again.

Sleep great, save money
Mattress shopping made easy!
3 year update -
Still as nice as the day I bought it.
No deformation.
No tearing or wear.
No smell.
No discoloring.
No issues.
Comes with a high quality, washable cover!

I've never been more satisfied with a mattress.
It's comfortable. Priced well. And beats dealing with mattress salespeople.
I've seen places try to sell you a mattress like this for 550$. Never go mattress shopping again.

I am a skeptic and a cynic - and I LOVE THIS MATTRESS
I am just going to be blunt here... I'm a crabby, cynical person most of the time. Or at least, I was. I am beginning to think that was a result of never in my life having gotten restful sleep. I can't really describe the feeling of waking up in the morning and feeling like I have the energy to face the day, instead of trying to figure out how I can sleep a little longer and not get fired.

We've only had the mattress a week, but in that time I have gotten the best night's sleep I've ever had, every single night. I'm not exaggerating at all when I say I wish I had bought this mattress two years ago. I'll update the review periodically and if anything changes, but for now I have to say that the rest I get on this mattress far exceeds anything I ever expected, hoped for, or believed possible. Really. It's that good.

The mattress is firm, but comfortable. Perfect, really, for this 240-lb guy. My wife can't feel it when I move around or get up- it's as if we are on two different beds. She's a much daintier framed person than I am, and she says the firmness is perfect for her as well. The smell that some reviewers noted was not an issue for us. The manufacturer has either corrected that issue, or we have a bad sense of smell.

I will close by saying that I am not a person who embraces change readily. If it isn't broken, don't fix it. I was not that excited about getting this mattress because I have spent the past forty-odd years of my life sleeping on a particular mattress style, and I didn't expect to like having to get used to a different type of mattress. I love my wife though, so when she told me that it was either me or the old mattress that would be leaving the bedroom permanently, I did what any loving husband would do, and grumbled under my breath while I ordered this mattress.

I hope my wife doesn't see this review, because she was right. 100% totally right. The sort of thing I will never hear the end of. This mattress is amazing.

From Firm To Soft In 6 Month
This went from being a slightly pliable cement slab to a saggy, mushy hammock in 6 months. So we probably got a total of 4 good months out of it. I only weigh 140 lbs and my wife weighs even less. I absolutely despise even the thought of chiropractors, but I had to visit one for the first time in my life today for the pain this is causing my back.

Not a good buy.

but you won't find anything that's more comfortable than a basic memory foam bed you can order ...
I've bought several memory foam beds over the years. You can spend thousands of dollars on big name brands in on-site stores, but you won't find anything that's more comfortable than a basic memory foam bed you can order online like this one for a fraction of the price. You'll probably want to replace whatever mattress you use in 5-8 years, so those that are advertised to last 20 years or longer aren't particularly useful anyway. This particular one didn't have the very strong sweet odor that memory foam products often have. Sometimes it takes days or maybe a few weeks for that odor to dissipate, but this product had just a whiff of that smell (which isn't offensive), and it was gone in 24 hours. Also, it didn't take more than an hour or so to expand to its full capacity. One thing about memory foam beds - they continue to "spread" over the long term, so you have to make sure to get a tight mattress protector and fitted sheets that will keep it from getting rounded corners and a saggy midriff. Finally, opening these can be tricky as they are so tightly wrapped that it's easy to accidentally slice through the mattress as you're trying to slit open the cardboard and then the plastic wrap it comes in. I would buy this again. For the price and the immediate comfort and good night's sleep, it's a steal.

Just the right amoount of firmness and had no odor unlike others
I have only had this mattress for a short while so my review to this point is only for initial quality impressions. I will update this review periodically as to how it is holding up.
I purchased this mattress in the 12" queen size for my guest room. That was the last room in the house we hadn't already switched from traditional box spring to memory foam. When I unpacked it the first thing I noticed was the smell. Or I should say lack of smell. I absolutely LOVE the king memory foam mattress that I have in my master bedroom but it took nearly 2 weeks for the odd chemical smell to go away. This mattress had none. We had house guests arriving 2 days after the mattress so this was a big concern.
Another concern was the amount of time it would take to decompress. In my experience it's anywhere from 24-48 hours. Again, with guests arriving time was of the essence. I am posting a couple of pictures with my review. The first was taken just a few minutes after unpacking. The 2nd was taken no more than 4 hours later any I'd say the mattress was 98% "inflated". I took a measuring tape to it and the 12" mattress was already 11 1/2" thick at this point.
We did still stay off of it for 48 hours but our first house guests to use it gave it rave reviews! They had never slept on a memory foam mattress before but were now looking into getting one themselves. They were absolutely shocked at how little we paid. They said (and after testing myself I agree) that the mattress is firm without feeling too firm. There is a little sink... but not too much sink. More like laying on a firm cloud.
This mattress will get more use than the normal guest bed as both my wife and I use our guest room semi regularly so as not to disturb each others' sleep when our work schedules don't coincide. I really hope that this mattress maintains it's current feel after any breaking in period. I will update soon and let everyone know but for now I highly recommend this mattress!

No more monkeys jumping on the bed.
This Mattress is great! I waited on writing this review for a couple months to be certain I wasn't biased from getting rid of my 12-year old spring mattress. It is wonderful to sleep on. Gone are my mornings of stretching and trying to pop my back and neck. I am a big guy - 6'4" 330Lbs, and the wife is a solid 5'11''. I was worried about sinking too much, but after reading hundreds of the reviews here on Amazon, researching foam density on my own, and fighting off salespeople at 3 different mattress stores We went ahead and got the 12" Signature Sleep King. Have I mentioned that this mattress is awesome.

We call it the giant marshmallow. Laying down on it you get the slow sinking feeling of a well earned sigh at the end of a long day. We also ordered the "Zinus Modern Studio Platform 1000 Metal Bed Frame" and it is a great height to sit on and put on shoes and socks, the edge does sink, but it does not throw you off. And bonus, without the need for a box-spring there is lots of storage underneath. The Hi-density bottom layer of foam prevents you from over-sinking and the memory foam on top is just enough to conform to my hip and shoulder even when I lay on my side. My only complaint, and it's not ever addressed in the reviews, is that it makes 'adult time' a little more work because there is no spring-back. The good side to that lack of bounce, is that there is almost no motion transferred, I could pretty much have a girlfriend over on my side without waking the wife on the other.

Love our mattress
Love our mattress. We bought it almost 2 years ago and it is still great. It unfolded nicely out of the bag and was ready to sleep on after 24 hours. There was a smell to the mattress, but since then has not been noticeable. Especially with a mattress cover. This mattress does get hot without the mattress cover on, but my husband sleeps with a fan next to him and that seems to help. So glad I found this and didn't have to pay the crazy amount of money other brands ask for.

bad mattress , avoid buying it
The mattress was not in a uniform shape, one side was 6" n other side 5". Did not like it and would not recommend to to someone too

Very comfy but can get hot by morning
Came rolled up, was easy to unpack and the odor problem seemed small to me. This is my first memory foam mattress and I am replacing an air bed. It took a couple nights to get used to the firm yet gentle support of memory foam but the way it traps body heat is more of an issue for me. If I fall asleep with even a thin quilt I awake overheated. I am finding by using just a sheet, or throwing off the covers when I first get warm enough I can reduce the accumulation of body heat significantly. Apparently, the sensitivity to too much heat varies widely among individuals so this may not be a problem for you.
The mattress comes with a stiff black backing on the cover so it works great without a frame. I find that getting up and down onto my 8" mattress on the floor is much less of a problem than I anticipated. The foam is so thick you can literally fall onto it with no fear of hitting the floor!

This mattress is Soft Hot Intolerable Trash
The manufacturer describes this product as "4 pound foam density/9 ILD-which is medium/firm". . . not true.
This mattress is SOFT, or Medium/Soft at best and one SINKS at least 5 inches while lying on it; maybe even a little more once the "foam support core" becomes warm with your body heat.
The packaging was nothing like the neat packaging of dual layer fabric and a plastic bag described in the instructional video posted by the manufacturer. Mine arrived unceremoniously wrapped in plastic film, and once it was freed from it, it became evident that its bottom was full of fabric debris and dust; not a good sign I must say in retrospect. Perhaps I did not receive the same quality of product that the manufacturer advertises on their Amazon post. Who knows, as most things from China, its quality was dubious straight out of the package.
The mattress was allowed to expand and regain its shape as instructed by the manufacturer. Heck, the girlfriend was over to stay the weekend with me, and we didn't even sleep on it for a couple of evenings thinking that it would firm up but no cigar. Fact of the matter is. . . This turned out to be a piece of junk that has brought nothing but sleepless nights tossing and turning and getting up to allow it to cool down a bit so that it regains its shape, to then start the same cycle of misery all over again. I'm definitely not keeping this hunk of. . . Soft Hot Intolerable Trash, and I hope that this review convinces you, reader, to think carefully before investing your hard earned shekels on it.
Save yourself the trouble and the sleepless nights, and spend the extra one or two hundred bucks on an American made product that has been tried and tested through and through.

I highly recommend if you like a firm and comfy mattress at a great price!
Absolutely love it! I bought the 12" king size almost a month ago. It's delivered compressed and rolled up in a large box. Just open, unroll and let it rise! See it in action in my time-lapse video:) NOTE: In the video it was under 12" just after opening but has since risen to the full 12+ inches.

It's a firm mattress but super comfy and when you lay down you feel yourself slowly sink into the mattress a few inches as it conforms to the shape of your body. With my old spring mattress I was having back problems and tossed and turned waking up multiple times during the night. With this mattress I haven't had any more back problems and have been sleeping through the night for the first time in years! The only issue I've had is that I've over-slept a couple times!

Priced right - but too firm.
We liked the price. That we give 5 stars!
The sheets stay on it - 5 stars
It is our first foam mattress so it just might be naturally SUPER firm -3 stars
But, it's very very very firm - if you like that then it's a great mattress.
Us, we prefer slightly less firm.
No odor - 5 stars
Love that it comes with it's own cover protector - 5 stars

Please let me know if my review helped!!

Dreaming
Well worth the money I would recommend to anyone with a size constrain such as RV or trailer use. Only downfall is it doesn't measure a true six inches but hey either do I.

this was a horrible mattress. Looks like it was built lower in the middle. There was no way to send it back it was sent to us. I had to trash this mattress. You can see the lower level in the photo

I'm one of those Amazon buyers that won't really give a review unless the product was exceptionally terrible or exceptionally go
Well, let me keep this short. I'm one of those Amazon buyers that won't really give a review unless the product was exceptionally terrible or exceptionally good. With this foam mattress, I figured I'd give a review on it since it is one of the pricier items I have ever bought online. I am a 22 year old male student roughly 6 foot and 205 pounds - this mattress is the perfect fit for me in terms of firmness vs softness. Believe me when I say that two people can easily fit on this mattress and be equally comfy. The problem with my mattress is that 2 corners never inflated fully so if you're standing above the mattress looking down it appears lopsided. You can only really notice the dip if you put your pillow in the corner (if you have someone else sleeping in the bed with you) I'm not sure if customer service will do anything to correct this, but I'll contact them later and let you all know how it went.

8 Months Later, Still the best Mattress we've ever had!
We purchased this Feb 8, 2014 and it is still amazingly comfortable, as the day we purchased it. We have the King 12" version. I spent a ton of time researching different types of memory foam, densities, materials, etc... and scoured countless forums and read hundreds of reviews on amazon. I narrowed it down to 3 mattresses and ultimately decided to go with this one based on price and the excellent reviews. We had been sleeping on a coil-spring mattress for about 4 years and it was unbearably uncomfortable. It became warped and didn't lay flat. We both slept horribly on it and I often had back pain if I slept wrong on it.

This foam mattress shipped in a few days and was delivered under our car port. I took it upstairs by myself. It comes bundled in a long cylindrical bag about 1ft in diameter and 7ft long. I cut it open and made sure to flip it the correct direction before opening the interior bag. It folded out and expanded almost to full height within a few minutes. The ideal wait time is about 48-72hrs before sleeping on it; however, we only waited a day. We haven't experienced any sagging or other issues in the 8 months that we have owned it so far. Some reviews mentioned a bad smell, but ours really didn't have that bad of an odor. We vented it for the night and next morning and then slapped on a mattress protector and called it a day.

It is very comfortable, but also very different than an innerspring. The best way I could describe it, is that it is more stationary and solid. If one of us moves, it doesn't move the whole mattress; therefore, doesn't wake either of us up. Some reviews mentioned that it is firm and not comfortable to lay on your side. I did find it immediately more firm than my old mattress; however, I have had the best sleep on it out of any other mattress I've had. I sleep on my back, stomach and side, just depending on what is comfortable to me at the time. I also did not note any more heat coming off/staying in the mattress than a normal mattress. I sleep with the ac on on about 70 though. As far as durability, nothing has changed since we purchased it. The dog has had a few accidents on it while we were gone; however, thanks to the mattress protector we purchased, it was unharmed (King Size SafeRest Premium Hypoallergenic Waterproof Mattress Protector - Vinyl Free). I am 6' 2'', 230lbs and my lady is 5' 11'', 160lbs, so combined we have almost 400lbs on the bed. I would say it can easily hold up to that amount of weight without any issues. It was a night and day difference between our coil mattress and would never go back. If you are on the fence, I wouldn't hesitate to grab this. It can be had for under $400 and you can't find a better mattress at that price.

Signature Sleep 12-Inch Memory Foam Mattress, Queen
Having dealt with several different air mattress companies on Amazon, none lasted more than 90 days before either their seams burst, they distorted way out of shape, had a chamber let go, or some other issue. This in spite of the fact that the bed was generally used one or two days in a weeks time. So, decided to just buy a Foam mattress since that should last and if you figured out what I have paid over the last 11 months, it should be cheaper in the long run. So, I ordered this product. Here is what I found:

1. First, do not believe the description provided on Amazon or the video on how this unit will arrive and what it will look like. Perhaps at one point the company actually vacuum packed this in a tight plastic roll and then placed it inside of a nice carrier that you could move around, but no more. The unit arrived as a tightly rolled bundle in clear plastic that was NOT vacuum packed and not contained inside of a nice Blue movable container. This roll was in a shipping box that had obviously seen much better days.

2. When you release the plastic, the unit expands and un-rolls. ENSURE that you have this where you want it PRIOR to cutting the plastic away!! Once it is open it is a monster to try and move around by yourself!!!

3. Once the unit is open, there are conflicting instructions that tell you to either use right away or to wait for 48 hours. Within 20 minutes, the center of the bed had inflated, but the sides were VERY lacking. So, I waited 72 hours to do anything with it ( had a convenient trip so I was away for that time). Upon arrival back home, the bed was mostly evenly inflated with the center being slightly higher. Sat on the edge of the bed and immediately sank several inches (compressed to less than half of the original thickness). Moved about 2 feet in on the bed and there was very little compression.

4. So, made up the bed and waited another 24 hours to try the bed. Still same issue. If you sit on any edge of the bed, you sink much more than you would on any other type of mattress. The longer you sit there, the more you sink in!!! After three weeks, it is still the same.

5. As for the memory foam, I do not think that does very much at all for comfort unless you weight very little. I weigh 200 pounds and the foam provides very little support. It certainly gives, but that is about the extent of it. My pillow top mattress that is 20 years old had a lot more support than this bed does.

6. If you sleep in the exact middle of the bed, it is comfortable and well supported. If you move toward any edge, you lose support. So, if you are only going to use this for one person, it will probably work fine. If you are going to use it for two people, you might have issues.

I am not sure if the problem is that the unit was not vacuum packed and so the edges have lost some of their lift or what. But if I had known that it would do this, I would probably not have ordered it.

This bed is probably more usable as an occasional visitor bed than ANY air-mattress that I have tried, but that is about where I would stop. If I was going to make any suggestions here I would say go to a regular mattress place and try out their mattresses and see if you can find one that will work for you. I think you might be happier in the end.

I was really expecting to love it. But for some reason
Given the high ratings, I was really expecting to love it. But for some reason, my mattress didn't inflate properly. It's lumpy and the middle inflated the 10 inches but the edges didn't. I'll update my review if the replacement is any better.

Very disappointed. CR from Amazon asked me to dispose the ...
Did not regain its size even after a week. My guest ended up sleep on the couch. Very disappointed. CR from Amazon asked me to dispose the mattress and they refunded the entire cost.

This bed is from the #Gawds!
I was very cautious about buying a memory foam mattress and even more so... Buying online/ site-unseen. I couldn't be more happy with my choice! This bed is a good dream factory and REM enducer! Coupled with a great mattress protector/ cover (which I also bought here on Amazon and wrote a review) it is the perfect addition to my room. Some peeps wrote reviews about a chemical smell... I didn't experience that at all... Maybe because I put freshly laundered sheets (lavender detergent) on it before I took my nose dive into my #REMCycle. This is one of the smartest buys I've made on Amazon in my 10 years of using this site. I'm going to add a photo of how complete my room looks now... And after I hit submit in this review... I'm going to dive back into my bed for another nap!

Defective unit or simply bad product? You decide!
Package was a wreck upon receipt. Notably, inner packaging, mattress wrapping is NOT as advertised or described. The mattress comes simply compressed in rolled up plastic, no "outer bag" as described. After 48 hours, this mattress has NOT "fully expanded," ends and edges are lumpy and misshapen. I have requested a refund through Amazon and will update results here but returns are simply impossible. Once you've broken the seal, without factory equipment and space to mechanically compress, roll and wrap, it will NOT fit back within the originally shipping box. You're either stuck with it or could try purchasing a queen size mattress box and try returning that way.
Noteworthy, I ordered the exact same mattress in a twin size for my boy. That box came clean and undamaged, although still no outer bag. Immediately that mattress expanded fully, I slept on it a few nights and loved it and after a few weeks I was confident enough to order the queen size for myself.
Before considering this mattress, read some of the "negative" reviews. I did, but after the twin size was nice I decided to risk it and purchase the queen. For me, that was a mistake. Way I see it, you've got a 50/50 chance...

Very Firm
I usually like a firm mattress but this was too firm. I bought it three months ago and finally realized that my back aches may be due to the mattress. So I purchased a memory foam 2 inch 3 lb density mattress overlay and instantly felt the difference. Much softer but not too soft.

Most heavenly bed of comfort
This mattress is amazing I purchased a full a year ago because I loved my boyfriend's , it's so amazing my mom bought a queen for her self. Laying on this mattress will literally heal your body! I like a firm mattress and my mom likes a soft but we both love this one because it's firm but then it forms to your body which makes it feel like heaven!!

Nice and comfortable
Great Mattress! I would've gave five stars if the packing wouldn't have ripped and my mattress wouldn't have a stain. That's a delivery and packing issue, but it's a great product.

Honest answer
Update: after a few months, we are still in love with this mattress. Best sleep I have ever had in my life. Go ahead and get it!! I will say that if you live in high humidity environments, the foam does become softer. We are in GA with average humidity and it is perfect for is. But I would recommend researching how your environment will affect the density of the foam.

So I was a bit skeptical about purchasing a mattress online, but after reading the 100's of reviews on this mattress I thought, How can so many people be wrong? I decided to purchase, and here is my experience. We received the mattress in a very short time, 4 days to be exact (ordered on Wednesday evening, arrived Monday morning). I purchased a platform bed to go along with this mattress, as we were upsizing from a queen to a king. The mattress arrived in great shape, and was vacuumed sealed to about 1" thickness, then rolled into a large tube like shape. Once we removed the outer packaging and exposed it to air, it inflated to full size almost instantly. This really was a neat thing to watch. We allowed the mattress to expand for 24 hours, but after the 24 hour mark we could not see a difference in size and it measured to a full 12 ". So we decided to go ahead and sleep on it. At first, the mattress was very firm. There is two sides to this mattress, one is just the white cover and the other is a grey side that has the zipper to remove the cover for washing. I accidentally placed the mattress with the grey side up then decided to leave it that way to see if it would be ok. It was waaayyyy too firm. After an hour, we flipped the mattress and realized there is about a 2"-3" soft foam on top of the dense foam that eliminated all of the firmness we were feeling on the other side. The feeling of this bed is hard to describe. It is soft and comforting, yet firm in all the right places. Moving from a spring mattress to foam, it has been an adjustment. I have adjusted well, but my husband says his butt and belly sink in and his feet feel awkward because they feel like they are elevated above the mattress. But know, this mattress is medium-firm. It is not soft and fluffy and a bed of roses. It is supportive, yet you feel the mattress molds around you. We are almost 1 week in, so I am hoping that our results stay positive! For the price, you are not going to get a better mattress. If you are wanting a PosturPedic, then skip this mattress and spend the $1500 on one. There is a difference in the price for a reason. This bed is great for Memory Foam beginners and those looking for an inexpensive option to comfort and support. If you are still sleeping on a spring mattress, its time to give it up and move on.

Happy Gambler!
Initial Reaction: I. Freaking. Love. This. Mattress.

Now, let's not get too ahead of ourselves, I only recieved the thing yesterday. But I am in mattress heaven. I am a 30 year old, 5'6", 125 pound female who has been sleeping on the same coil spring mattress since I was 19. For the past I-don't-even-know-how-long I have not been sleeping well. I'll wake up in the middle of the night tossing and turning and cannot go back to sleep. Maybe once every three nights I would get a good-night's sleep. But, overall, I've been one very tired, very grouchy girl. Needless to say, I decided it was time for a new mattress.

Now, I'm not gonna lie, I had probably every 12-inch, full-sized memory foam mattress on Amazon "in my cart" at one point. I just couldn't decide which to pick. Ultimately, I came to this conclusion: Buying a mattress online without trying it out first is a GAMBLE. A big one. Now, I figured I could afford a $270 gamble much more easily than I could a $450 or $600 gamble. If I didn't like it, that would suck. I'd be mad, but at least I'd only be out $270 and not $450-$600. I'd be mad (Hello, single teacher here! I don't have deep pockets!), but I could survive it. And, given the reviews, ratings, and specs on this mattress, I decided to go all-in.

I'm feeling like I should hit up Vegas now or something, because it seems my gamble has DEFINITELY PAID OFF. This mattress is firm, but not too firm. Goldilocks-style, you know? Just right. Firm enough for sleeping on my back, soft enough for sleeping on my stomach or side. Every part of my body sinks in and is supported evenly -- the key word here being "supported." It fully supports ALL of me. And, for a girl with a butt my size, that says a lot. Generally my lower back, just over my butt, gets little to no support, because my big ol' hiney is taking it all. My upper back and butt make an arch and my lower back between gets left unsupported (like a foot with a high arch in a shoe with no egg). Lumbar support is my BFF. When I first laid down on my back on this mattress I really and truly felt little tingles in my lower back. It was like it had never felt the support before and it was cheering for it. Happy back = happy me. And on this mattress, I'm happy on my tummy, my side, and my back. I'm just... Happy!

Here's what I should note: I am a single girl and my adoration for this mattress is based solely on that. I have no idea how it would hold up if shared.

As far as pictures go, you can see pictures of the mattress from the product description, so I decided to add pictures of the packaging. The box it came in was a little beat up (and its ink got ALL OVER ME, so watch what you're wearing when you haul that box around!), but the mattress was still secure in its plastic wrap inside. While nothing was wrong with my mattress, I could easily see how others might get damaged in shipping. I guess that's just another gamble you have to take. And it was a little hefty and awkward to maneuver, but I managed to get it to my room, on my bed, and inside my mattress protector all by myself (and I'm no He-Man!).

Do I think you should buy this mattress? That's your gamble to take.

too many issues to give a third shot.
I unfortunately had to deal with the large items department to return this mattress twice as i received defective or not as advertised mattress twice.

Good:
I didn't notice any smell chemical or otherwise.
comes shipped in a bag that was easy to open and remove.

Bad: just about everything else.
Soft, but probably too soft. my three year old is enough weight to make it nearly compress to the box spring. maybe just two defective ones?
The packaging said made in china, but not really surprised.
The first mattress only expanded to just over 5 inches at the edge, and might have a peak around 6.5 or so in the center. (see picture)
The 2nd mattress only reached 4.5 inches and it had some sever deformities around the edges. I've shared pictures that show how only the middle sagged and never expanded. one corner was still flat and wouldn't expand. the inner edge that was wrapped the tightest (center of the role) was wrinkled and never recovered from shipping even well after the recommended 48 hours.

bottom line. I'l look elsewhere.

Update: after receiving a 2nd mattress with issues i purchased another one by visco kids from amazon. here is the link.
http://www.amazon.com/SilverRest-Sleep-Shop-Kids-Pink/dp/B004LE0R72/

Surprisingly comfortable.
I just moved into my first (own) apartment and needed furniture. Sleeping on the floor is nice at first but gets old very quickly. I knew I wanted a queen-sized bed. Did not have a bedframe at first. Very surprised with the packaging, and to be quite honest, was skeptical about the comfort of the mattress (due to the low-profile nature... my previous mattress was a sealy pillowtop).

Immediately after unpacking, it aired out and measured just, under 6-inches thick. I slept on it that night, regardless. It was quite firm. Eventually purchased a used Ikea Malm bedframe and slid the mattress on top of the standard slats. It really does look quite nice. I've been sleeping on this mattress/bed for about 2.5-months now. I can't tell if I'm just getting used to it, or if it started to soften a bit. The mattress did seem like it contours and soften much better with time. Maybe its the slatted base too.

I recently went back to my parents' house and tried out my old mattress... I missed my new bed immediately.

Take-away message: Comfortable, but fairly firm at first (compared to a pillow-top). Modern-looking with a platform-style bed. Gets more comfortable with time. Slatted frame base may help with even weight dispersal and allows the bottom of the mattress to "breathe".

Great at first, 2 years later it's like sleeping on a flimsy marshmellow with no support.
I really enjoyed this mattress for the first year, year and a half. Then my lower back started hurting, and about the same time my wife started complaining about her left shoulder hurting. This is the side she sleeps on. She slept in our guest room bed for about 2 weeks with no shoulder pain. Then came back to our room for the last week she has been complaining about her shoulder again. Well, it's been about 2 years now. Today I spent a lot of time examining the matress and observed that it was flimsy like a marshmellow. I actually sink in to it without the firmness and support it had when I first purchasec this mattress. This would explain my wife's shoulder pain and my back ache.

Looks great! Exactly as I imagined thus far...
Just received this 8" twin version yesterday and am already very happy with what I see. Am letting it expand for the full 48 hours recommended before sleeping on it, but by touch it feels nicely firm and has a good tension to its surface already. The picture I've included was snapped less than 15 minutes after unwrapping, and the unwrapping was simple. I did NOT need to use a scissors to open the package. Also, there is ZERO odor. Shipping was quick. I'll update this review once I get a sleep or two under my belt with it. But so far, looks excellent!

UPDATE: Okay. I've slept on it and it is exactly what I wanted! A very firm mattress that provides excellent support. Again, this was pretty much full size within 24 hours and expanded quickly from the start. Also, again I will state for the record, there was ZERO odor with this. Just a great, great product!

SECOND UPDATE: And just for the record, per the info the came with the mattress, the actual dimensions are 75"L x 39"W x 8"H.

A YEAR LATER UPDATE: So. I've had this mattress for a year now and... I still love it! There has been no deterioration of the firmness over time. No odor. It has been perfect. I am very happy that I purchased this particular memory foam mattress and if and when I need a larger size, this brand will be at the top of my list of considerations.

Risk worth taking
Just had my first night sleeping on it! It was great, so comfortable. I think it was the best night sleep i had in a long time. One small issue I had was with shipping. I chose one day shipping with Saturday delivery becaue I'm moving in my new place on Saturday. It didn't arrive. So I had to sleep on the sofa for two miserable nights. But this has nothing to do with the mattress. It's all ups' fault. Amazon was really quick to refund me the shipping fee so that's good. Now back to the mattress. It came in a box which means it is easy to handle. A bit heavy but I had no trouble getting it to the third floor by myself. Unpacking is very easy too. You just need to be careful only cut one plastic cover (there are two) at a time. I accidentally cut both at the same time so the mattress was getting inflated in the middle of it, which didn't cause much problem though. Since I'm starting off in a new place, I have a bunch of other things to build and assemble. Unboxing the mattress might just be the easiest task.

People warned me against buying a mattress online and I was skeptical about it myself. But equivalent product in local stores will cost at least twice as much. Eventually, after reading many reviews, I decide to take the risk and I'm glad I did. Now I hope this review will be helpful to you if you are uncertain about purchasing a mattress (this one in particular) online (Amazon specifically).

This was just as nice as all the reviews said! We are VERY happy with this purchase!
This mattress is MUCH nicer than any other memory foam mattress we looked at! I got this to go on the top bunk of my 3 year old son's new bunk bed and we are SO glad we went with this instead of the one at Ikea that was $25 more. This one is about 1.5" thicker than that one, but I felt like this mattress is much more dense than the other one. My son has slept on this mattress for 3 nights now and he hasn't woke up any of those nights (He is usually up at least once a night, so this is a big deal!). I really feel like he is sleeping so much better on this than he was on the traditional inner spring mattress that he was using.

I was pleasantly surprised at how fast it fluffed up out of the package as well. I pulled it out a day before we set the bunk bed up, but it was fully fluffy and ready to use within about 6 hours. It did have a slight smell, but it was MUCH more tolerable than a lot of other memory foam products that we've tried over the years, and it was completely dissipated within 24 hours. If you stick your nose straight to the mattress now, you might be able to smell it a little bit, but its very very minimal.

Edited to add: the zip off cover is a phenomenal addition! So handy for cleaning!

Overall, I'm SUPER happy we went with this mattress! I think we will probably be getting another one to put on our guest bed as well!

Best thing I ever did
Wow! Best thing I ever did. I was having lower back pain every morning sleeping on a too soft mattress. Since I began using the memory foam, absolutely zero back pain. Love it. Like the way it was packaged and shipped too; environmentally conscience. No odor or anything, just unpacked it, let it expand and began using it. I'll never go back to a spring mattress. Thank you memory foam!

Very cozy!
I've been sleeping on this for about 2 weeks now, and I'm kicking myself for not buying sooner! Very cozy.

Do NOT buy. The worst!
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.

Mold on the bottom of mattress
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.

its like sleeping on the bottom of a crater
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
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.

Sleep Master, Indeed!
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!

and they mostly get very good reviews. This model
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.

I have a problem with this mattress....
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!

Awesome mattress not the cheap oem that comes with the rv.
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.

It's comfortable enough for a good night's sleep
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.

Best mattress ever!!!!
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.

Very Good Mattress at an Excellent price.
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 never want to get out of bed now...
*** 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!

One even said it's like sleeping on a marshmallow
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.

Foam is not just for beer anymore!
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).

Memory Foam Take Me Away
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.

Great value for a standard size mattress, exceptional value for a short queen.
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).

I was hesitant because some said its not good for daily use
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!!

Sleep Master 8 inch purchased 1 year ago
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.

Terrible mattress...Replaced after a year
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.

Awesome mattress for those on a budget!
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.

Has made a world of difference for my overall sleep and body
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!

Read this
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.

Wary at first, but a great deal
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

Love this mattress!
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.

Will buy another!!!!!
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

Size is not correct
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...

Fantastic mattress!
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".

Comfort and nothing but. UPDATE 4 yrs after
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.

Look no further, this is your mattress!
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!

Looking forward to restful nights again.
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!

Quiet but can be quite hot.
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.

Decreased Quality after 1 Month
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.

Comfortable if you like memory foam mattresses
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.

Nice Mattress/Good Price
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!

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

This is the ultimate deal
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.

Working well for a antique 3/4 bed!
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.

Two different experiences
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.

This is now the best feature of our camper trailer!
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!
