Some sleepers report that these mattresses are comfy., but other folks have had different experiences. Although these mattresses have above average reviews, there are some caveats. Get more information below to see if one of these mattresses will work for you.
Mattress supportiveness is an important factor for everyone -- especially stomach and back sleepers. Also, deeper support that keeps the spine aligned with the rest of the body is an essential trait for side sleepers. These mattresses offer sleepers above average support. However, others had issues with the support so if you have a heavier body type, make sure to do extra research.
Most customers like the support in the edges of these mattresses. But, some heavier customers may experience some dipping close to the edges.
Reviewers provide mixed ratings about the durability of these mattresses. We're all big fans of mattresses that feel just as great as they did 10 years ago as they do today, but sadly, not all are built to last. If a mattress with mixed feelings on durability is on your short list, make sure to do one last look at the warranty and return policies so you are protected.
Having excellent ratings from sleepers is an important factor for shoppers. Customers give these mattresses higher marks than most competitors, which should give you a good starting point to learn more. Research on below to discover if this mattress will work for you!
Mattress support is key to a healthy night sleep. You want something that will prop you up rather than sagging and hurting your back. Reviewers describe these mattresses as well supportive.
For those that like sitting on the side of the mattress, edge support is very important. These mattresses do a well with edge support and don't sag too much on the edges.
Bowling Ball & Density Tests
Popular among reviewers, the bowling ball test provides a good indication of firmness while also showing evenness of support across the mattress. If a mattress isn't even in its support, some folks may experience back pain or other issues. Luckily, these mattresses have good ratings here and shouldn't have that as a problem.
It's a big win financially if your mattress is super durable and remains comfortable. It's one more great reason why durability is top of mind for mattress buyers. However, any shopper reading the reviews knows there are brands that seemingly don't care about the same thing. Even with that, there are still some great products and brands out there. These mattresses are very well rated when it comes to durability. These mattresses should do a great job for up to a decade for those of average builds. Those who are heavier may have slightly time.

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.View More Reviews
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.
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!!!
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!!
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!!!
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!
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!
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!
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!!
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!
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.
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.
I had the same mattress in queen. It was wonderful so I decided to buy the same in King and it is awful. The bigger size has no support in the middle. So the sides feels like the queen, but the middle sag tremendously and therefore gives no support at all. After 2 years of back pain, I have finally enough money to buy a different one. This was so disappointing because I still have the queen and still love it.
For a mattress that is above the norm; The 10" pad is very supportive of a 260lb man. A Very dreamy firmness and this mattress is easy to lift the corners during making your sheet fit well. The overall weight is about -85-88-lbs, and ladies are able to shift the full mattress with easy. Upon receiving the purchase, the unit did not smell of any odd chemical fumes, and We just enjoy the best sleep and naps of our Year. . . . The value in a modern mattress is a good investment, and the quality will provide a good 15 years span to your resting world.
This was great at first. It was very firm which we loved. It slept a bit hot but we made adjustments and got a wool topper. But now 4 years later-I am waking up throughout the night with shoulder and hip pain. After some reading I find that memory foam can 'soften' and lose support. I am so annoyed that after 4 years my mattress is failing.
I bought this Mattress 2 weeks ago, it came on time but the mattress is not inflated to 10 inches. The cover is still have baggy and feel like missing layers
Bought this model from Costco a few years back. One big reason I chose this one was the design included firm(er) foam edges (that you can't feel), but they help the edges not just compress to nothing when you sit on the them - and it really works. Fast forward to last month, bought another of same model for guest room. While new cover is nicer, mattress is a little softer and... no more firm sides. ;( Yes, the description shows a drawing that shows it still has foam wedges along the edge, but the design has changed so they look smaller, and are definitely not effective. Sides compress down to almost unsittable level. Returned and will replace with (sadly) one that has more robust edge support. Guess Sleep Science figured out what the 'money' feature really was.
After years of suffering from a traditional mattress, I was ready to make a switch. It took a few weeks to get used to, but I'm so glad I bought this mattress. It is very comfortable!!
I bought this mattress a little over 2 years ago and it is the worst I've ever slept on. I have had back issues ever since, and thought it was due to the fact that I picked up playing golf right around the same time. After traveling for work over the past year and a half, I realized my back is always fine as long as I'm not sleeping in my own bed. A friend just told me Costco would take it back so I will be returning it ASAP.
I’ve been using this mattress for about 7 weeks. It seems to have a ridge in the middle, and it feels uneven to me. This is our third 10-inch Sleep Science mattress, and the first to feel uneven.
We have 3 Sleep Science mattresses now and love them. We sleep so sound and deep. We feel great in the morning
We've been sleeping, and I do mean sleeping, on this mattress for six weeks now. I was in physical therapy for my back when the therapist asked me, "Could it be you need a new mattress?" I came home, looked at our Sleep by Number and decided we did.
We purchased this bed over 6 months ago and I waited to do my review to see how it lasted over time. It was a bit firm for me (a side sleeper) but my husband liked it. We purchased a three inch foam topper a few weeks later and it really helped with my shoulder comfort. Between the topper and the mattress, I sleep so well!! We are very happy with our purchase, would recommend for someone who likes a firmer mattress.
We purchased this for my 6'5" son in college because he had the 3rd floor loft up a spiral staircase and we could not get anything up the stairs. This mattress comes condensed, in a box. We had no idea what a great mattress it was until we visited and stayed in his room and could sleep through all the FSU football weekend noise! Since then, we purchased mattresses for our two daughters and two more for our beach vacation rental condo. We have had 3 couples so far that rented our condo and actually ORDERED the mattress while they were still staying in the condo so that it would arrive at their house before they returned. That should tell you how good this mattress feels. It's firm, but not too firm. It gives great support. If this mattress only lasts 10 years, for the price, and the quality sleep we get, it's priceless! Come stay at our direct ocean, corner condo and try it out while you enjoy a New Smyrna Beach, Florida ....call it a "research trip"!
I ordered this mattress from Costco and before I had even received it, I had a letter from the company to thank me for the purchase and contact information should I have questions or problems with the mattress. I have been using now for a week and really like it. I am a side sleeper and this is perfect for me. I would not hesitate to order another when I need one!
This was the second Sleep Science 10" foam mattress we've bought and it is even better than the first one. (Usually memory foam mattresses outgas for a few days after being unpacked, but there was zero odor this time.) We bought it for our guest bedroom and we still have the six years old mattress in our master bedroom. The Sleep Science memory foam mattresses are the best value in memory foam for price and performance over several years. We miss our mattress dearly whenever we travel and sleep on hotel/motel beds. We are 100% satisfied with these Sleep Science memory foam mattresses and recommend them to everyone!
Had guests in for 10 days and they were delighted to have such a comfortable mattress to rest on while on vacation. The mattress was reported to "hug" their bodies and it appeared to have great recoil to it's original state after being vacated for a few minutes. Would suggest it for a guest room.
We bought this bed for our guest room, because we enjoyed the bed we had bought 2 years ago for our own bedroom. Sleep Science had a great mattress. Thank you Costco!
hypo allergy , firm mattress exactly the that I want , at same time soft enough to give me excellent sleep .
I already returned to costco. It is listed under firm and it was very soft and spongy. Its great if you like a very soft mattress
I knew I would get good quality beds at Costco. We bought queen plush & wanted 2nd bed to be firm. Very happy.
Early indications are this Sleep Science mattress is a good product. However, there is an important CAVEAT: Sleep Science memory foam mattresses must be supported with a solid base. I purchased a platform bed from Costco with the mattress. The bed had slats as support. I was told by a Sleep Science Rep that I would need a 1/2 inch thick piece of plywood to properly support the mattress. I had two bad choices: 1. Try to (re)box a 78 pound bed and return to Costco. 2. Buy the plywood, have it cut to fit, and, somehow get it home. I chose the plywood. What a hassle. While I recommend the Sleep Science mattress, I caution not to buy platform bed with slats to support it.
Bought this Queen Sleep Science from Costco in June 2015 for a summer home. Read all the reviews and thought it would work but it's just too, too hard. Cheaper guest bedroom mattress is more comfortable! Awake with pain every morning. Finally added a memory foam topper last year to make it bearable, but we're replacing it now - Year 3 (total sleep time slightly more than 12 months!).
Despite waiting a over a month, the corners of the mattress never filled out to be fully 'square'. Instead they round off and don't fill the mattress cover completely.
Even more than a year after ordering, our son still comments on how he loves this bed.
We weren't sure buying a bed online & in a box would work out for us, but we have been very happy with our new mattress. At first, it feels really firm, but then it gives way so that hips, shoulders, etc are cradled. I am amazed at how light the mattress is, too. When making the bed, it's super light when picking up the corners to tuck in the bottom sheet. I thought it would be really heavy, like other memory foam mattresses. Overall, we're very happy with our purchase.
The bed is the perfect firmness for my back. I am able to wake up without pain. Costco shopped it very quickly! Thank you!
I bought this mattress 5 years ago. I researched extensively to find a firm mattress and based on good review I bought this. People shouldn't review any mattress until they use it for at least a year. Many reviews here written are just after a week or few weeks. Most of the mattresses would feel nice when new. The real test starts after a year. We loved this mattress in the beginning. Perfect amount of firmness, edge support, no hot flashes etc. After a year it started to sag n sink. We're not even large people I was 135lbs and my husband was 160 lbs. I started to wake up feeling really hot and back started to hurt. In just 2 years this mattress was really uncomfortable and some how we tried to manage it with some toppers but nothing worked. Edge support is gone, foam is of very poor quality. It has actually caused me severe back pain. I do not recommend this mattress. This is the first product from costco that I really really hate.
We bought this mattress thinking it’s firm . Backache started after first sleep on it. Called Costco to return. Costco return good , mattress bad bad.
This is my third Sleep Science Mattress. 1st was a 13” Queen which I gave to friends after I had it 10years. I had to downsize. They still say it is the best mattress they have ever slept on. The 2nd was a twin which was better than other conventional mattresses but I went on to this 10” full size to get back the 3” wedge support all around and it is a much better mattress. I suffer from bone pain and with this mattress I do not have it. The only Con to these mattresses is that they are warm so if you live in a hot climate consider that. If you live where it is cold it will make it an extra plus. I will buy another when this one wears out which I don’t anticipate happening any time soon.
Our son and daughter-in-law recommended Wink. We find the mattress to offer us great firm support for aging backs. Delivery was a breeze. Don’t think you will be moving this mattress around, as it is very heavy.View More Reviews
My old mattress had given up on me. I woke up with a backache every day. After much research, I decided to try the Wink Bed. Really glad that I did... After one night, my back was feeling better and now, after a few weeks, it is gone and I am back to normal. This is one of the better decisions that I have made recently. Thanks!
I’d die happy because I slept on my extra firm wink bed :)
The mattress is super comfortable. However, want to note a few issues. The delivery people almost could not get the king mattress up my stairs because of the thickness. I have a 90-degree angle on my stairs and that was the problem. Also, it rubbed the ceiling. No damage, just a few scuffs on the wall. Second problem is the weight of the mattress. Very heavy. I'm 70yo and am having issues changing the sheets on the bed. I don't use a boxsprings, Instead I have a 4-sided bed frame that contains the bed. Can't use the mattress lifter item sold on Amazon and elsewhere. It only works with a boxsprings. There are no handles on the side of the mattress, so cannot lift it. Handles would have been nice maybe. Rotating the mattress is impossible unless I get friends in my house to help. I'm open to any tips on making the bed or rotating the mattress. Love the comfort of the mattress...just wish I didn't have the problems. BTW, can't use a boxsprings if I bought one. Too rigid and big to go up my stairs.
Bed is very comfortable and service was excellent. Definitely will buy again when I need another mattress.
I'm really pleased with the bed so far, it has just enough firmness, quishiness and bounce! Construction seems very sounds and the delivery process was seamless. As skeptical as I was about ordering a mattress online, I'm glad I did. I would totally recommend this bed to others.
This was our very first online purchase of a mattress. We spent considerable time researching exactly what we needed/wanted and decided on a Wink Bed. What a great decision. I had considerable back pain from our older mattress but after a few sleeps I had no pain. Our first few sleeps took some getting used to ... we purchased the Luxury Firm and it is a firm but just the right firmness. I would definitely recommend WinkBed. Should you prefer something not as firm there is a softer option!
This mattress is everything they say it is. It supports and it's extremely comfortable. We especially like the edge support. We replaced a tempurpedic mattress that we paid almost three times as much for and this mattress is much more comfortable.
I had been sleeping on a waterbed for past 40 years. My back wasn’t enjoying it anymore so I started researching mattress options and reviews. I found Wink Beds and thought it offered me a high quality product at a value price. My wife was still comfortable on the waterbed, so we decided on the Soft Plush as a compromise. Delivery went very well and involved 3rd floor condo. Mattress was much firmer than expected. My back was comfortable with more support, but it didn’t have the plush feel I had hoped for with Soft. We slept on for a month and was still too firm for my wife. I contacted Wink Beds regarding my concern and options. They suggested a mattress topper and offered to ship one out free of charge. We have been sleeping with topper now for a week and it has come closer to the softer, but supportive feel I was looking for. I’m happy, comfortable and getting a good night sleep with no aches or pains anymore. I would definitely recommend a Win Bed, but only if you are looking for a medium to firm mattress.
Very good bed. High quality. We checked out many,many beds and determined this was best for us. Figured we saved close to $1000.00 compared to brick and mortar store. In addition if you don't like bed you can return it to Wink within 100 days. With store bought you can only exchange in store which begs the question if you couldn't find what worked the first time what do you expect to find the second time there.
I am highly statisfied with the service and quality of my mattress and box spring.
Thanks to numerous reviews and the ability return the mattress, I chose to buy a Winkbed. I am so happy I did. The process was easy. The bed is so comfortable and I am sleeping better. Kudos to the Winkbed folks!
Returned our Saatva after 2 months due to the feeling like you were going to roll off. This new Winkbed is very comfortable and has great edge support. Ordering and delivery was flawless.
The order, delivery and personal service/attention are 5 stars. It's hard to determine a mattress by description only. It is good but I wonder if the firmest option would have been a better choice for back support.
love this bed!
We have been looking & comparing mattresses for a year & decided on the WinkBed...glad we did. The reviews were great, the price was right & we liked the try it if you don't like we will come & get it at no cost to you return policy. The first mattress we rec'd had a highly noticeable manufacturer's defect & they immediately replaced it for a perfect WinkBed mattress. The mattress is comfortable for a side sleeper (like me) or a back sleeper (my spouse). My hips used to go numb on our old mattress & I was constantly waking up changing sleeping positions - not so on our WinkBed mattress. I can sleep on the same side all night long with no problems. We love it.
We have so been enjoying our new mattress. It’s the best of both worlds- coils below and memory foam above.
We purchased the firmer option knowing we like firm beds. We like it a lot. It is firm but still soft, and no sinking, which is what I really don't like. Delivery was easy (for us)--the delivery men got it up to our third floor bedroom up twisting stairs! Awesome job on that. Would recommend to others.
I really like the mattress. My only reason for not giving 5 stars is because within 3 weeks the mattress started to yellow. Super comfortable, matress, great price Just one issue.
What a difference your mattress has made. I now sleep so much better and through the night too. Thanks WinkBeds.
The moment I lay down in my Winkbed I am instantly relaxed. I can count on falling asleep quickly and waking up in the morning without any aches or pains (something that I couldn't say with my last mattress.) I love the mattress depth and the overall feel (soft enough its comfortable but firm enough to be supported.) I am a side sleeper and I haven't had any shoulder pains from excessive pressure either. This is also a good bed for couples... no more rolling to the center of the mattress!
My wife and I have been very pleased with the mattress. Keep up the great work.
Love my new WinkBed! Just the right amount of support. I have had it now for a couples of months and my night time back aches from my old bed are a thing of the past.
Understand correlation does not indicate causation BUT for the several months before receiving my Wink mattress I was dealing with some nasty lower back pain. Been sleeping on my new Wink for about a month and the pain has diminished to the point where most days there is none. A plus is that the mattress is super comfortable.
Took a leap of faith to order this bed online without testing it. After 1 month find the winkbed very comfy. Great edge firmness. I sleep on my side and my wife sleeps on her back. Both of us get a very comfortable sleep.
our comments are directed to the box spring we purchased along with the mattress. First the was/is a small hole in the fabric of one of the box springs on the side about the size of a quarter. Also the box spring is slightly larger than the mattress. The mattress does not fit squarely on the box springs. John Howell
very comfortable. I have a bad back and your bed allows me to get a good night's sleep. Thanks!
I am so pleased with my WinkBed experience and the quality of my mattress! I wanted coils and firmness and quality fabric and a consistent sleep experience - no rolling into a crevasse in the middle of the mattress and you provided all three! It was wonderful to get exactly what was advertised and tonso at a very reasonable price point.
I think its good. I seem to be sleeping fine. Probably need longer to determine for sure. Delivery was great.
Super comfortable mattress! I'm a side sleeper and this mattress is the best I've ever slept on. Love it!
Wonderful bed that gives both of us a great night's sleep.
Really enjoying our new WinkBed mattress. Very comfortable to sleep on...about my only complaint is how heavy it is when I'm trying to make the bed and lift the mattress to get the sheets/blankets tucked in under it. But, otherwise, very happy!
The firmer bed is fantastic ... just the right amount of soft on top of great firm support. We love it!
We purchased the luxury firm mattress, and we couldn't be happier. I have had back problems since I was a teen, and I wake up pain free each morning.
Best mattress we have had.
Love my wink bed. A tad bid higher than I expected. But thats okay...
Great Customer Service. Love our luxury firm Wink Bed queen mattress.
We went for the firm mattress and LOVE it. The guide was really helpful- go with firm if you like to feel “on top” of your bed not “in” your bed. The quality is really good, clean white and sturdy. Highly recommend the delivery with set-up as this mattress is WAY heavier than most inner-spring mattresses! Enjoy and Thank You Wink!
We had tried a foam only mattress from another online company and it wasn't a good fit for us. We looked into hybrid foam and coil options and landed on Wink. We have been really happy with our purchase and have adjusted quickly to comfortably sleeping on our Wink bed. We never achieved this sleeping comfort level with our previous foam mattress purchase even after 80 days and had to return. Glad to have found Wink!
Great bed Firm support yet comfortable.
