Novaform

Novaform mattresses are well known for being sold in Costco warehouse locations. Owned by memory foam developer and manufacturer Innocor, nearly all of the mattresses sold by Novaform are memory foam mattresses. Also found at popular retailers like BJ's and Sam's Club, Novaform's product offering and quality differs slightly per retailer. However, overall, with a variety of mattresses in different thickness options, Novaform gets some good initial feedback from customers. Still, there are some reported issues with heat retention, firmness, and initial comfort in some cases.

Sleep Science

Sleep Science manufactures a line of latex and memory foam mattresses. Some of their mattresses feature materials such as bamboo charcoal, gel, and copper infused memory foams. Additionally, they are Certipur certified for low VOC and no formaldehyde in their mattresses. Sleep Science is well known for their 'wedge' technology which helps promote edge support, and for being sold at Costco warehouse stores where they are available for a competitive price.

Novaform's Owner Satisfaction

Sleeper reviews can be hard to understand from a high level -- especially with brands trying at all costs to protect their reputation. Sleepers, sadly, don't always feel comfortable from these mattresses. There are still folks that love their mattresses, but there are many others with complaints. Learn more details about the mattresses below.


Novaform's Supportiveness

In terms of having support long term, these mattresses get mixed reviews. Some feel like the mattresses provide good comfort, but others had issues with discomfort. If you are someone who is above average in weight or has wide shoulders or hips, you may want to do additional research to make sure these mattresses will work for you

Edge Support
Edge support is an important item for anyone that likes to lounge on the side of their mattress or has mobility concerns. Some may not find these mattresses to be evenly supportive along the sides and may dip more than usual.


Novaform's Durability

We all want a mattress that lasts 10 years or more, and when we instead buy a mattress that causes us discomfort after only a year, we feel cheated. However, now more than ever, it is getting harder to find lasting comfort. With more types of products than ever before, some brands aren't investing as much in quality. When it comes to these mattresses, some sleepers had issues with durability. That doesn't necessarily mean that durability issues will happen to everyone, but make sure to read up more before buying.

Sleep Science's Owner Satisfaction

These mattresses received mixed reviews from sleepers. Many folks describe feeling comfortable on their new mattresses and sleeping better than before, but there were others that didn't share the good feelings. Make sure to read on for more information on if one of these mattresses will work for you.


Sleep Science's Supportiveness

Most reviewers report that these mattresses do well with support, but others reported feeling some discomfort. For those that are plus size, read the customer reviews before buying as you'll want to make sure that your spine is aligned properly.

Edge Support
For those that like sitting on their mattress with their feet hanging off the side, these mattresses support most folks with good edge support. That said, some have had issues over the mattress life so make sure to review more if you need edge support for mobility reasons.


Sleep Science's Durability

Mattresses don't provide as long-lived comfort as they used to. Finding a mattress that lasts over 15 years is hard to find. That said, finding a long-living and comfortable mattress can save you thousands. Unfortunately, these mattresses get mixed reviews on durability. Many sleepers don't report issues, but others have complaints about durability over a shorter time frame than usual.

Good if willing to put a few extra bucks into it
Pros: Price, shipping, delivery, ease of getting into bed room, highly rated by consumer reports
Cons: Firmness is mislabeled, requires a memory foam topper to be comfortable

I did a lot of research before buying our new mattress. We had never done a memory foam mattress before and thought we would give it a try. We went to a department store and tried out their memory foam beds to make sure we thought we might like it and picked the right firmness.

I have traveled for a job and stayed in nice and bad hotels. I thought I was pretty experienced to differ mattresses and comfort levels. This one is rated medium firmness, I would say it is medium firm to firm. It is much firmer than any mattress I have slept on. I could see how it could be firmer so I won't say it should be rated firm, but it is at minimum medium firm. There is no feeling of memory foam. There is almost no give in the mattress. You expect a memory foam mattress to give to your body a little and you fit into it. This does not happen with this mattress. I was excited to see what the pearl gel memory foam felt like. There is no indication of pearls, gel, or memory foam on the top layer.

Awesome
After researching mattresses for months and with great fear I ordered this matress based on Costco's return policy, consumer reports rating, and customer reviews. It arrived by courier ( He even dollied it into our bedroom )! It unpacked as it should. No smell , no waiting - we slept on it that night. I had left the board that I had been using on the box springs but after a 2 weeks removed it because I read that it should not be used on the floor but on box springs. It went from firm to medium and viola. Perfect!!! I've had the matress over two months and purchased gel pillows. Honestly, I've never had anything this comfortable. The gel pillows work in sync with the matress. It's NEVER hot. But now that it's winter it's not cold either. I'm just in awe when I lay down at night and even more pleased when I wake up. Great job Novaform. Great Job Costco! My first purchase from your company has made me a life long customer.

Great Mattress and Price but too firm
I have had this mattress for @ 2 years. I think it will probably last forever, but it is NOT medium in firmness. I would say at least medium firm +. You do not sink in as you do on most memory foam mattresses, but surprisingly I do sleep very well on it. It really doesn't feel like a memory foam mattress. Seems good for both side and back sleepers. I do wish it was a little softer. Slept on a water bed with 'pillow top for years until the bladders could no longer be patched. They don't make water bed mattresses like this anymore (solid pillow top and sides that drop over base and bladders. Probably this was the most comfortable mattress I've every had. Unless you like a soft mattress you will be very happy with the Serifina' and at $650 ($799 Cal King which I have)nothing else comes close.

Bought it, returned it, opted for diff product
Lesson learned- don't skimp on a mattress you spend 7-8 hours using and if you have back/neck problems. Wife and I bought this and gave it a ride for 30 days. Felt it was too soft, did not hold form. Returned it after 30 days. It came in a box the size of a dorm room fridge. That should probably be a characteristic of caution in the first place. Might be suitable product for college kid looking for something that can ship easy. Not a great solution for neck/back problems.

Deserves 10 stars!
For years we wanted a Tempurpedic so when Costco.com offered them a couple of months ago, we took the plunge. For six weeks, I did not sleep. The Tempurpedic was hot, hard as a brick, and uncomfortable. It was also excessively tall.

We returned it and replaced it with the Serafina Pearl Gel Mattress. Oh. My. Gosh. It is like sleeping on a cloud. I like a softer mattress while my husband prefers a firm mattress. We are both happy and are sleeping through the night with no tossing or turning. Do not hesitate to get this mattress!

Too Firm
Costco service and delivery and price were all great. I just could not stand this bed. It was not medium. It was very firm. Felt like concrete. I switched to the Valentina and I love it.

Too Hard
I bought this mattress a month ago and haven't gotten use to it yet. Will probably send back. Will maybe try the more expensive softer mattress.

Extremely comfortable
Having had a 15 year old firm mattress the change to this memory foam mattress its everything I had hoped it would be. Sleep on both side and back, both very relaxing and comfortable.

Great mattress
We needed a new mattress, so I researched them starting with Consumer Reports, which rated this their top foam mattress. This is our first foam, so I really didn't know what to expect. Also, we have never purchased a mattress without first trying it out in a store. It arrived quickly and was fascinating watching it expand after to cut the plastic off it. I have to say that it's harder than I expected, but I am getting used to it after two weeks. My wife, who sleeps on her back, is sleeping noticeable better. There's also no movement transferred to the other person, which is a good thing. Neither of us noticed any unpleasant smell as some have reported.

HORRID!!!!
Relying on the glowing review in Consumer Reports, I purchased this mattress more than two months ago and believed the enclosures that said it could take a while for the mattress to fully set. Well, sufficient time has elapsed and it is still the most uncomfortable mattress I have ever slept on. (It replaced a 16- year-old mattress but thank goodness I hung on to that one because I plan to put it back on my bed and give this mattress away.) The mattress is so hard, I wake up with a backache every morning and my Activity Tracker shows I am having very restless nights. I actually have to fold up several blankets and use them as padding under me because the mattress is so hard and uncomfortable. I would not even call it 'firm,' it is the hardest mattress I have owned and I always buy firm models to provide more back support. Worst money I ever spent!

Great Mattress!!
I researched alot of mattresses on their comfort, side and back sleeping and reviews and price. This one came out on top. We used to have a waterbed and thought it would be difficult to adopt our lifestyle to a regular bed. We got flannel sheets and have slept like a baby ever since. It's hard getting out of bed in the morning. Very nice.

Great Bed, Great Price
I bought this bed in February 2016 and like the other reviews found it very hard. After about 2 months, it become much more comfortable. I love it now, find it very comfortable, doesn't make my back hurt and I would certainly buy it again. You have to give it a few months and then it's great. If you are looking for a pillow top snuggly bed, this is not for you.

Great Mattress
We bought this a month ago and cannot be more satisfied. We did think it was slightly more fim then we expected but after 2 nights of sleeping we realized it was a medium firmness. The most comfortable mattress ever. Havent slept this well in years.

Perfect for me
1. I read all the reviews on the COSTCO, other sites and checked consumers overall this bed seemed to be a good choice as far as quality. 2. As you can see from the reviews some people say this bed is to hard, some say it is to soft and others say it is just right. Depending on your weight depends on how much you 'sink' into any mattress that also effects how hard of soft the mattress 'feels'. 3. I enjoy a 'firm' mattress in which I do not sink a lot into it but I do expect it to conform to my body this mattress works perfectly form me. 4. Smell: Upon delivery I set up the mattress and aired it out for about 6 hours. I then put on a mattress pad and bedding. The only way to smell anything unusual was to put your nose to the mattress and that lasted about 2 days. 5. Price: After checking warranty and cost this bed via COSTCO gave me the best value.

Very firm
I did hours upon hours of research and thinking before deciding on this mattress I read every review posted. How firm a mattress feels is different for everyone so how can you yourself decide until you have one.? I needed a firm mattress for my back issues. This one was rated so well and it was a no risk purchase. I decided to give it a try. I am a woman approx. 130 pounds. My weight didn't put a dent in it anywhere! I felt like I was laying on top of it with little to no give at all. It also took a couple of days to expand to be able to press a hand impression into it. It did not get hot, The smell of it was minimal, it is very heavy, easy set up and this is an good quality mattress. I was hoping it would conform to my body a little but it didn't. For me, it's as firm as any Firm mattress without plush or a pillow top I've tried out there. The medium firmness rating doesn't feel accurate for me or my weight at least. It's harder than the highly rated Se@ly kelburn also recommended by CR. Hope that helps as a way to compare for you. Love Costco and always will!

Novaform @costco review
If you've owned a high end pillowtop mattress you will not be satisfied with this bed, If you haven't its perhaps doable, For the money right aroud 600 dollars its worth the money, It actually helped my wifes back, And she woke up without her usual discomfort, For me it felt to firm and lacked that luxurious feel and its not something i can imagine spending 1/3 OF MY LIFE ON FOR THE NEXT 10 YEARS, That being said again its still worth the money.

Promising
We have tried a number of the Novaform mattresses. Each one seemed to have great promise but fell just short. We love the affordability and potential of the mattresses. Our first Novaform serafina pearl gel memory was too soft (rated in top 4 on CR), but nice if you like plush. We then tried the Novaform firm memory foam, which was firm and comfortable but retained so much heat that I was waking at night changing shirts from sweat. And finally the serafina pearl firm with gel, once again too soft. I must admit, I have had lower back problems, so I look for firm to extra firm mattresses. For now, we are giving up on foam mattresses.

Provides support and gently hugs you
I've been sleeping on this mattress for a few weeks now and find it to be comfortable. The mattress is softer than I prefer with a very plush top layer that hugs your body and offers support (at the lower back). You do sink into the mattress a bit which can slow you down when changing sleep positions. Before this mattress, I slept on a foam mattress - it retained heat but I feel this mattress retains more heat. My spouse really likes this mattress though. There isn't any edge support. There is an off-gasing smell that lasted up to 48 hours after unpacking. Overall: nice support, a little too soft, retains heat but I like it.

Not Supportive
At first we thought this mattress would work for us, but after a week we knew it wasn't supportive enough. We are 60 and 59, 230 and 130 lbs respectively. I am a side and back sleeper, my husband a side and stomach sleeper. I noticed that the mattress didn't hug my lumbar region while sleeping on my back. I could feel a gap there and there shouldn't be. My husband thought it was too squishy, not firm enough. What we both disliked is that the sides cave in when sitting on the edge of the bed, so you basically slide off. We had to return it and we are now trying a Sterns and Foster pillow top firm. Back to basics for us.

The best purchase ever!
We were moving to Ireland and wanted to buy new beds for everyone but we had a budget as moving countries is expensive. We gone One queen and the kids got full size each. I was very nervous as we would not be getting to try them untill we were in Ireland. However, I need not have worried. They were the best purchase ever! I normally have back issues and have never woke up even once with stifness or soreness in my back. Still totally love this bed after nearly 10 months. My only issue is now when I visit friends or stay overninght else where, the beds seem completely sub standard.

Firm cradling comfort
My husband and I bought this to replace our 7 year old tempurpedic. This Novaform 14" Serafina is the most comfortable mattress my husband and I have ever slept on. That includes all mattress's at hotels, friends' and that we've owned. We're in the mid 50 to early 60's age range. It gives a firm but soft cradling support and is not hot like our previous memory foam. We read reviews in Consumer Reports and this met our budget and was one of the top rated mattress's. We got it on sale and is a great value even at full price. Highly recommend!!

Takes getting use to.
We purchased this mattress last year for a vacation cottage. We allowed it to sit opened on the bed overnight before we slept on it. We own a pillow top mattress at our home, so this was our first Memory Foam mattress and we purchased this based on good reviews and the price. The first few night we slept terrible! We both woke up sore each morning. After about 5 nights we finally started sleeping better. I do find it to be hot, especially if you are sleeping on your back. It is soft on the top, but very firm underneath so you have good support. We are going to buy a mattress topper to try and soften it even more to what we are used to sleeping on. Overall for the price it is a good mattress, but does take time to get use to.

More of a medium firm
I love having a king bed, it is lovely! First time trying out a memory foam mattress. My husbands only request was to get a firm mattress. I would say its more of a medium-firm. You do sink in a little right away. I woke up the first week with sore back, which I never have before on my other spring mattress, but I haven't recently, so I am wondering if my body had to first get used to it. I also am 19 weeks pregnant, which could have been part of it, or that the first week we didnt have a platform for it yet!! Me or my husband havent had any issues with overheating on it like I read in some of the reviews.

Great mattress
This was a first....after shopping all over for a firm mattress, (costs were &1200-$4800+). Reviewed Consumer Reports, this mattress was very highly rated and less than $1000. Then it went on sale in February!!! With Costco's return policy we decided to give it a try. Then we learned it would be coming in a box!!! A king mattress in a box!!??!! When it arrived...in a box...flat as a pancake...there was no way this was going to work.....wrong....within three hours this 'pancake' turned into a full size king extra firm mattress!!! No more tossing and turning it's the best nights sleep we've had in a very long time...granted, it's only been a week...but so far so good. Would and have recommended this mattress to everyone we know.

Excellent !
I researched mattress online. This one came in the top 10 at number 5 . I bought this mattress 3 months ago. I always had a coil mattress and needed a change. I knew I could return it if I was not happy. Costco is great to deal with if there is a issue. It is the best mattress I have ever slept on. Extremely comfortable, not hot, my back even feels better. My wife feels the same way and she was really concerned. She is not tossed around when I move or turn over.

Firm was better than medium firm
We tried both the firm and the medium firm version of this mattress. The medium firm was available in warehouse and the firm only available online. My wife chose the firm version do to less motion transfer and no sag/roll toward the center due to my laying in the bed. She was able to get rid of a boomerang pillow she previously needed for side sleep with our Sleep Number bed that we got rid of. It took about two hours, a roll of heavy duty packaging tape, clamps, 2x4's, and a vacuum to get the medium firm mattress small enough to return to Costco...but they did take it back.

Too Soft for Us
Frankly, my one star is probably unfair, but if you love a very hard innerspring, as my husband and I do, do not be lured in by the "firm" label. That's firm for a foam mattress, not firm for a mattress in general. We sunk into it as if it were a marshmallow. In fact, after trying it for a few nearly sleepless nights, we dragged our old rock-hard innerspring mattress onto our bedroom floor and there until we were able to lift it off our bed and arrange to return it to Costco. We are SO thankful for Costco's return policy. I cannot imagine sleeping on this huge marshmallow for another night.

Disappointed
We bought the mattress online through Costco only because they don't carry California Kings in the warehouse. It two weeks to get it. Unpacking it was not to difficult. It's been a week since we've had it and the mattress still hasn't fully reached its full shape. The bottom right side is still smashed. As for comfort, the only option was to go with firm in a cal king. It's like sleeping on flat mat, there is no give, no comfy feeling. I can't seem to find a comfortable position and my lower back is achy in the morning. Will give it one more week like the instructions recommend but doubt very seriously I will keep it. Not at all what I hoped it would be, the delivery time, the shape not right and the total lack of comfort, especially for the money.

Life Changing
My only regret is not buying one sooner! I'm so glad that I took the time to go lay on a few different beds first. I even got fitted by one of those computer beds that measure all your pressure points to figure out how firm of a bed you need. Being a big guy (6' 300lbs) I'm so glad I went with the firm Serafina. You do sink in a lil little, but only really enough to form to your body. I have nothing bad to say about this bed and would recommend it to anyone.

Finally a FIRM comfortable bed.
Many thanks to Costco for their return policy. This is the second mattress I have purchased from Costco in the last six months. It is quite firm which is what I needed. The first purchase seemed fine for about two weeks, but then the "sleep impression" began to appear...sort of like a troth.

I was hesitant about buying
I was hesitant about buying and surprised to receive it in a box, but what a great mattress. I am 6'4" 320lb and the firm is surprisingly comfortable for me and my 5'3" 123lb wife, We love it. A !2" mattress might have been better, our deep sheets are not deep enough for the 14" mattress

Great Bed
I bought this bed a couple of months ago and love it. It’s the perfect firmness. It’s very similar to the Tempurpedic medium firm and softer than the Sleep Science Black Diamond. I’m a side sleeper and it does not hurt my shoulder like the SS Black Diamond did. This bed is an incredible value, especially when it’s on sale. I highly recommend it if you have laid on the Tempurpedic medium firm and like that firmness level.

Serafina Ordered Accidently...
So we ordered a "bed-in-a-box" from Costco, thinking we had ordered the King sized Novaform Comfort Grande. Shortly after receiving an email confirmation, the email read "Serafina Pearl." Initially, i was scrambling through different websites to see a comparison of the 2 beds. The Comfort Grande was said to be less firm than the Serafina Pearl. I was thinking that the Serafina may be too firm as the Comfort Grande eluded to the fact that it too was a firm bed. Now that I have received the mattress and have slept on it for a couple weeks now, I am so happy that we stuck with our accidental purchase of the Serafina Pearl. The mattress has the perfect amount of firmness that my wife and I prefer. Also, the king size makes this bed even more amazing as we often share it with our 2 kids and a 70 lb dog.

Perfect Amount of firmness
Let me start this review by saying that everyone is different. Back problems run in my family. I am only 26 and I have back issues already. I workout, I stretch, I walk, I do yoga, but all of that won't matter unless I have a quality mattress. I tried an online mattress company, and it was super comfortable, but made my back pain worse because it was too soft. This is the perfect amount of firmness. Give it a few weeks as you would with any mattress. Your body may be sore because it needs to adjust to a new mattress. This was well worth the money and provides great support. The only con I can think of is the weight. It will be tough to move. But it is worth it!

My only problem...
My only problem is that there appears to be no way to determine before you purchase what firm means when comparing foam mattresses of different companies. Our first firm memory foam mattress from Costco was 7-8 heard old and finally lost its rebound. Our new foam mattress labeled firm is as soft as our sagging old memory foam mattress. Is possible it was mislabeled? Thanks for listening. W F Bolin

Heat - Heat - Heat!
Mattress gave off unbearable heat. Not sticky, sweaty heat - just steady, intense heat. Impossible for me to sleep. For ages, at home, hotels, friends' homes, I fell asleep very quickly after laying down - usually 1-5 minutes. With this mattress, if I was lucky, I'd finally fall asleep 90 minutes after laying down. Then I'd wake up every 60-90 minutes because I needed to sit up or turn to let my back cool off. (I normally sleep like a rock!) Tried for over 2 weeks thinking maybe it would ease. Extreme disappointment as quality otherwise seemed good. Minimal odor - way less than expected. Pretty firm but not overly. But the heat was crazy horrible. Had to return.

SOFT & HORRIBLE
I just bought this mattress less than 1 week ago. I desperately needed a firm mattress following a recent bad back injury. This mattress is NOT FIRM BY ANY MEANS!!!! You sink down into it, and it's difficult to get back out of bed. The sides cave in when you sit on the side of the bed.

Best Mattress Ever!
This is hands-down the best mattress that we've ever owned! We were a little hesitant to purchase a foam mattress, having heard stories of how hot they were to sleep on and how hard it was to move in the bed. However, we have experienced neither problem. The bed is not hot and neither of us have experienced any problems moving on the mattress. We both sleep better than we ever did on more expensive mattresses and for the first time in many years, I have no back stiffness when I wake. We bought the mattress to replace a Sealy hybrid that was only 3 years old but it was no longer comfortable to sleep on. I highly recommend this mattress.

An awesome bed!
My wife and I have had our bed for about 3 weeks now and we couldn't be happier! This mattress is top quality and is amazingly comfortable. No more neck, back and hip pain. Couldn't be more pleased with our purchase. This bed is "bang for the buck". Our last bed we purchased 10 years ago and paid 4 times as much. Our new mattress is so much more comfortable and the rest we get is incomparable. Highly recommend! Two thumbs up!!

DO NOT HESITATE TO BUY
My wife and I bought a Simmons BeautyRest Mattress two years ago for $1800. After 6 months our spine/hip health started decline. Going to orthopedics etc and spending money that wasn’t necessary to find out after buying this Novaform mattress, our 2 year old mattress was the cause of ALL of our issues. We got the firm mattress and it’s the most amazing sleep we’ve had in forever. Do not hesitate to buy this mattress. For $800, it saved our hip and spine health. Do NOT get caught up in the lies of mattress store prices or sales people.

NEEDS GOOD FOUNDATION - dont use bunky board!
We bought this mattress over a year ago...had no idea that they sold a separate foundation. Spent months replacing the bunky board we got from Crate and Barrell 2 times and dealing with back pain, even called the mattress mfr. The mattress mfr said they recommend their foundation instead of bunky board. Ordering it today, hopefully it will take care of the problem but paying $50 more than if I bought them together from the start. They need to update the description and recommend the foundation if they don't buy it separately OR don't even sell the mattress alone. Description said it needs a 'solid' foundation...what does that even mean? I had a hard time trying to find a bunky board that is solid wood from many retailers. Crate and Barrel's new bunky board is made of compressed cardboard! A painful process, but I like the mattress.

Works well for us
The mattress is definitely on the firm side but we both find it about right. After 11 months, the bed seems to be wearing very well... no signs of change in feel or shape. The adjustable bed is used in zero gravity every night for one of us and not used at all for the other. The adjustable bed works well for back sleepers but not side or stomach sleepers.

Six years later, we still love it!
This bed is the best we have ever slept on, even 6 years later. We have the queen, and now want a Cali king (we now have a dog sleeping with us), and will be buying another one of these latex matresses from Costco. This one will go into the guest room, and it looks brand new. It has not settled or sagged at all, even though it is used every night, by 2 people. It is NOT hot, either. The memory foam mattress we bought from Costco first, was hot, however. So we returned the memory foam and got this latex mattress. We are so happy!!!

Not so great!!
I did what i thought was plenty of research before i bought this bed.. I've waited a full year to try and get used to it, and kept telling myself and my spouse it would get better. Not only was it hard and uncomfortable but, from 3 months on, it had big depression on both sides. It seemed to get worse , not better! The only good thing is i bought it from Costco, so they agreed to take it back, no problem! Yea Costco!!

very good customer services
I bought this bed on July 7, 2016. It was my first Costco online shopping. As in warehouse shopping, the online service was very good. The delivery company did not call me to confirm the delivery time but Joshua and Carlos did great in the delivery of the bed and setting it up. Brandon at the distribution center was excellent. I could test the bed before the purchase. The latex mattress feels cool in summer compared to other types of mattresses. I hope I enjoy my bed for many years to come. I love shopping at Costco!!!

Super Comfortable; great support
I've purchased 3 of these mattress so far. The first one about 3 years ago, then another one the following year and another one a couple months ago. the first one was in a guest room and the other two were for two of my kids who loved the bed when they slept on it while visiting!

Helps with my back
I bought this bed over 2 years ago, maybe 3 years now. My husband was a reluctant buyer, because we are only early 40's :) He thought adjustable was for the nursing home. But he had enjoyed it just as much. It hasn't helped his snoring, but he enjoys the leg elevation and massage features after a tough day or workout, and elevation of his head when congested. I have had a couple of back injuries from car accidents, and sleep considerably better on this bed than ANY OTHER!! We had a memory foam before this. This is NOT memory foam. Memory foam sinks in with your weight, then when you turn over you fall back into the rut you created. Ours was also hot. This foam doesn't radiate heart back at you. I love that! It doesn't sink in. It has great support. It is nice to be able to sleep elevated without getting up in the middle of the night to prop up or go to the recliner. My bed sleeps just like it did almost 3 years ago. No sagging, indentions, or soft spots. It does creak a little when adjusting, nothing a little wd-40 can't fix. The base and massage features still work like a top. No problem! Good buy!

L-O-V-E IT!!!!!!!
Purchased and received this split King organic mattresses with adjustable bases on April 8th, 2016. What a great product! Both my husband and I absolutely love our mattresses! The adjustable bases fit perfectly inside our existing bed frame, and the mattresses are sooooo very comfortable. I have always been a side sleeper, but no more! I'm able to easily sleep on my back now. Since I am a professional singer, this is a real plus for me. Also, the adjustability allows me to (among other things) raise my head ever so slightly to allow for sinus drainage as well as legs for additional perfectly tweaked comfort. The mattress cover is soft and also feels luxurious. A 3 inch layer of softer 19 ILD natural latex perfectly compliments the firmer 32 ILD layer underneath it to softly cradle with no pressure points yet support my body superbly. Adjustable base works great. Fully articulates for customization. Zero Gravity pre programmed position is heavenly! Don't wait. Buy this now!!! You'll be glad you did! Great price and great product. Thanks Sleep Science - Well done!

Wonderful Bed!
We got this bed a couple of months ago. It is very comfortable. Unaware another person is in the same bed. Mattress is fine for us, not too firm and not too soft. No odor.

Delivery company had great personnel.

One side had a control box (located under the bed) that failed in the first few hours. Costco called the company and we had a new one installed by the company in a few days.

I would suggest going to check out Dreamfit mattress covers (they come in twin xl and their kings sheets (2 twin xl bottom sheets with one King top sheet. Their bottom sheets and mattress covers have extra elastic straps to hold the sheets in place. I found these after much research. They stay in place great. Love my bed!!

Comfortable..natural latex adjustable
The mattress delivery was great..even on time. The mattress itself is nice ...no sinking in like foam. Soft and supportive. The adjustable base is great. I do wish the lights on the remotes would come on before you try to poke the right button. Zero gravity setting is awesome!

Very comfortable
Its very comfortable. Firm for support but not too firm. My wife & I think it is the best mattress we have slept in. No smell at all.

It's SOFT, not 'medium with a bounce'
Disagree with the SUBJECTIVE product details 'Sleep Science comfort scale: medium with a bounce.'

There is missing objective ILD firmness scale info in the product details. For me, 5'3 and less than 120 lb, this is surely a soft latex mattress. In general, The 'soft' designation corresponds to an ILD rating of 19-21. The ILD rating for the medium range is 24-26. After digging yourself, then you find this mattress has ILD 19 on the top 3 inch layer over another 6 inch of 32 ILD.

Mattress
Best mattress I've ever had

Comfortable and pressure relieving.
The delivery was early by several days and happened without notice, but luckily we were home to receive the mattress. Unpacking and getting it ready for use was seamless and fast; we didn't have to wait for several hours and slept on the mattress within hours of set-up. So far, the mattress has been comfortable, relieving pressure in all the right places while providing support. I wake without the aches and pains I had come to assume were "normal" as I grow older. I am optimistic that it will continue to be as comfortable for many years to come.

Very Very Very Firm
We found this mattress to be extremely firm. We bought a softer topper to help but unfortunately it did not. We have purchased 5 other foam mattresses for ourselves and family members and had been very pleased. This one was just too firm.

Awesome mattress
Mattress is so firm and comfortable!

I love my bed!
We picked this up because I have a bulging disc in my back and even though our other mattress was only 3 years old, it wasn't cutting it. I Love This Bed!!! We've only had a couple of months but so far so good. It's firm the way I need it and supportive. I'm a big guy 6'2 270lbs and it's great for me.

Perfect mattress !!!
It’s a very good mattress and my mom loves sleeping on it. The mattress is true to the firmness.

Great firm mattress!
Love it feels great for my back and gives plenty of support. Even better you don’t feel any movement when there’s someone next to you.

My husband and I both love this bed! It keeps us from getting overheated (a big issue of mine) and is the perfect firmness. This is our favorite bed after having two other gel cooling foam mattresses that have also been purchased recently. Actually, this is our favorite bed we've ever had and we are both 60.

Very happy with purchase
Very happy with this purchase. Mattress is super comfortable and the firmness just right for both wife and I. (Of course firmness and comfort are subjective and very individual.) The adjustable functions work great and motors are pretty quiet. This was a major factor in our decision as my wife just now had shoulder surgery and sleeping in a reclined position is needed. Packaging and assembly are quality although it would be recommended for 2 people to carry base pieces and mattresses from delivery location to bedroom. Assembly video very helpful. Time will be the teller for durability, but very happy with the purchase and first impression.

good
the bed is comfortable but its been only 1 week since I have been using it.

Favorite place
Love my new Sleep Science split king bed and adjustable frame. I have only slept in in the last 4 nights so this is an early evaluation. We had a temperpudic for the past several years but this has surpassed that at more than half the cost. So far this bed is my favorite plays to be.

WORST MATTRESS EVER
Don't waste your time and money . I had this mattress for more then a month. An every morning i woke up with sore Back .I am been using memory foam mattress for more then 10 years and I never had such a horrible mattress for the price i paid . I am glade i got it from Costco so I could easily return it ..

Good mattress
Good mattress that was delivered one month late. Came rolled up. Have to let it rest for 3-4 days to self inflate and acquire firmness. Since its brand new cannot say how long it will remain firm

Great bed & purchase.
Great bed! Sleeping great & elevate when needed without disturbing spouse.

Worst purchase
Terrible mattress. Got it delivered after a month after it’s shipped (which is after a week after I ordered). Mattress has some stains on the bottom. Couldn’t spend another month and half without a mattress so opened it. Both Costco and sleep science have deceived me to the core and lost all the respect and trust I had in both these brands. It’s not firm at all, people who love plush would rate this below plush rating. I’ve no energy and time now to deal with the customer service at Costco which discontinued email and chat supports. Staying on phone with them for hours and getting mediocre resolution isn’t worth.

Mattress comfort
Sleeping was too warm and too firm

Mattress
So far so good. Hoping for a number of years of the same. Attractive and comfortable.

Very good quality mattress!
Very good quality; perfect firmness and it’s a good looking matress.

Advertised firmness not as anticipated.
Mattress was advertised as extra firm and we have found after 2 weeks of sleeping on it the areas where we sleep are already getting soft. Not sure if we will be able to keep it.

Seriously could be saving my marriage with this
My new wife has complained about how much I enjoy sleeping (i.e. I occasionally snore) which apparently keeps her awake. I had a 10 year old sleep number bed that she despised sleeping on because she prefers a firm mattress (firm as in she'd be more comfortable sleeping on the floor than a soft bed) and I was more flexible. She'd mostly started sleeping in the spare bedroom every night because of these two factors when I saw this bed go on sale around memorial day. I figured why not give it a shot and if it didn't work out, we could always return it. Well right from the very first night she noticed a difference where I slept in the zzzz setting and didn't make a sound. That kept up for weeks until we took a small trip and stayed in a hotel room and the snoring returned. We both totally looked forward to coming back to our bed. I've been sleeping comfortably and so had she. Now we can both sleep together in peace.

Very satisfied with this purchase
Super comfortable. Easy to assemble with two people. We love the adjustable settings. Zero gravity is divine!

Extremely firm
This is the most firming bed i ever experienced. May be too firm.

Sleep Science 14” copper infused cal king
Excellent bed great support

Mattress
It IS a from mattress of very good quality. The massage and adjustability of this bed are great. I’m hoping it softens some, I’ve had it for one month.

Haven't slept so well in years.
After 1 month we are very happy with the purchase. Firm but very comfortable mattress is exactly as described. Motorized stands work very well and seem to be high quality. The price was less than half of what we saw in bedding stores. We should have purchased sooner. My only comment would be that a set up and mattress removal service should be offered.

worst buy
started great...slowly sank and now i feel like i am sleeping in a pothole. it went from good to worst really quick. not happy with this purchase but happy with costco policy. they are awesome.

How good the bed is.
I had the bed for 1 1/2 months, it served whatever expectation I have for this bed that's why we bought it. Me and my husband likes it a lot.

Too firm for me
Sleep in this mattresses for one month. Good quality but just too firm for me.
