Suffer from tossing and turning? It could be because your current mattress doesn't support and align the spine properly. That's where Level's TriSupport™ technology can help. Level's technology is a marvel in zoned support with a high-end all-foam design made in the USA. While the shoulders and hips are relieved of pressure, the middle spine is supported properly. Ideal for back and side sleepers, the Level Sleep mattress is perfect for those that suffer from back discomfort and need long-lasting support. With a patented design and supported by chiropractors, it has been clinically shown to reduce morning stiffness.
Sleep Science builds a line of latex and memory foam mattresses. Their claim to fame is their 'wedge' technology that provides edge support to every piece of the mattress. Additionally, they are Certipur certified, which means they have low VOC and no formaldehyde in their mattresses. They also use bamboo material in some of their mattresses. Their mattresses are made popular through their relationship with Costco warehouse stores where they are sold at a competitive price vs many of the retail sold mattresses of similar material quality.

Finding a brand that keeps its customers happy is a good first check mark for looking into if a mattress is right for you. Reviewers score these mattresses very highly versus others. Do some more research below to figure out if one of these mattresses are right for you.
Even support is extremely important for sleeping well, and these mattresses do a great job with supporting sleepers. Supportive mattresses don't always have to be firm mattresses. The important part of support is whether it supports a healthy spine. These mattresses are excellent at aligning the spine and providing that kind of support.
Do you want to sit on the side of your bed without the dip? These mattresses will provide a comfortable seated position on the sides of the mattress so you can take your time getting up or putting on socks or slippers.
Bowling Ball & Density Tests
Some reviewers use bowling balls to show the firmness of a mattress on its surface layer. Even support is one of the most important things to see during these tests. These mattresses are consistent with their firmness and support and react well to shoulders and hips.
Designing higher quality mattresses that last is a difficult issue for mattress brands. It means they have to invest in better product technology -- like foam and coils, and perform better in product tests. Also, it is difficult to measure at times because it is such an individual experience dependent on body weight and use. That said, these mattresses are rated exceedingly well on durability and based on the current information, should last a decade or more for most sleepers.

Reviews are an excellent way to get at the benefits of a mattress. That said, it is sometimes difficult to stay focused with all of the reviews from countless brands. Based on recent reviews and overall customer sentiment, these mattresses have some mixed emotions. Some sleepers are extremely comfortable, but others aren't as happy.
All sleepers need a supportive mattress and especially back and stomach sleepers. Side sleepers also need deeper support and a responsive mattress for their hips and shoulders. For most reviewers, these mattresses provide a good amount of support. That said, some folks didn't feel supported enough so if you are heavier, make sure to do extra research.
This mattress does well for most in terms of providing edge support. Over the long term, some had issues with dipping along the sides.
Mattresses don't last as long as they used to in years past. Finding a mattress that lasts over 15 years is hard to find. Yet, finding that diamond in the rough can save you lots of money. These mattresses get mixed feedback when it comes to durability. Some customers report no problems, but others have issues with the durability over a shorter horizon than average.
I'm a chiropractor and I have been looking for an orthopedic mattress for myself, as well as something I can recommend to my patients. I've had the TriSupport Mattress now for almost 2 weeks, and I am very happy with it so far! It successfully supports the spine's curves and is comfortable in all sleeping positions. I have noticed an improvement in my sleep quality too (fall asleep faster & wake up feeling more rested than before), which is an awesome added bonus. Stellar customer service as well. Thank you!View More Reviews
We upgraded to a king after having a queen, and couldn't be happier! This mattress provides amazing back support! I had just gotten shoulder surgery, and as a side sleeper needed something super comfortable for my back - no pain, and love may be converted to back sleeping!
I really love this mattress, it is very supportive in all the right places. The staff are very helpful.
For years I have had to put a wad of socks under the middle of my back to give me the support I needed to lay on my back. With this mattress I no longer need to do that. I also had issues laying on my left side putting pressure on my hip and making it feel out of joint the next day. With this mattress I have a lot less of that issue as well. I am very pleased with the purchase.
I noticed less tossing & turning the first night I slept on my TriSupport mattress. After a few more nights, I realized I wasn't snoring as much if at all! I like it's firmness and that I don't sink into it but rather sleep on top of it. It's comfortable sleeping on my stomach as well, however, I find I do not wake up on my stomach anymore because I'm quite comfortable sleeping on my back or side. I'm very happy with my new mattress!
The trisupport mattress is wonderful. The varied supports in the mattress lend itself for a painfree, relaxed sleep.
We were a bit apprehensive at first ordered 2 mattresses and couldn't be happier being a side sleeper my shoulders are in heaven sleeping better than ever Thanks
We have had our Level Sleep mattress now for one week and so far so good. It did take some nights (3) to get used to it and find the "sweet spot" for greatest comfort, but since then, we have slept great and have had no back trouble whatsoever!
we finally spent our first night in our new home on our sleep level bed. It was so comfortable. Jim said he felt very comfortable in all hia sleeping positions. I slept very soundly as well. I was going to send a note to thank the team for there great service.
This mattress and pillows are worth every penny. Have been have great night sleep ever since. Should have bought this month's ago. Thank you for everything.
I found Level Sleep through a friend and then was welcomed into their cozy Sonoma home store to one on for style. While the mattress in the store was amazing and is what prompted my first purchase for my new place; it was not until 30 days of incredible sleep that I appreciated the beauty of the TriSupport Mattress and Level Sleep's innovative technology. The stress of moving paired with other life altering events left me quite sleepless, but there was something in the comfort of my Level Sleep mattress that helped me sleep like a baby. More than 120 days in, my mattress continues to provide healing and restful sleep as promised. I am a believer! Thank you.
After swapping out my expensive mattress for the much cheaper Level Sleep mattress, I wasn't too impressed, but after a few nights I started waking up without my normal back pain (from my L5/S1 fusion area) that I had become used too. Maybe I didn't align myself vertically in the right position, but I really became a believer and a huge fan on the Level Sleep technology as it is the best mattress I have ever found for alleviating back pain. Way to go team. Great Mattress and a Great price too!
I've been struggling with back pain for years. My chiropractor told me about this bed and What a difference! The bed is firm enough to sit upright in as well as support you while you sleep lying down. It does not move around or disturb your partner like many other beds. I used to wake up every morning so stiff and sore in my previous bed. The price is also extremely reasonable! The bed came in the mail and was easy to set up
I'm so grateful my chiropractor suggested this mattress. For anyone who suffers with fibromyalgia, it is an answer to prayer. I also have a herniated disk & OA. This mattress provides the different levels of firmness/softness where they are needed most & I couldn't be happier.
I've been telling my friends about your intelligently made mattresses that we found to be very comfortable with support in the right areas. We've tried other mattresses that disappointed us rather quickly. We first put your mattress in the guest room and guests loved it, but then we decided to put it in our room and have been much happier than with our older, expensive yet sagging mattress. We recently stayed at Whitehall Hotel in Chicago that advertises as having the second most comfortable beds in a hotel....don't know what brand they use, but your LevelSleep is right up there if not better....
I am very happy with the level sleep mattress. I have struggled to find a mattress with the right support for my lower back that is also comfortable and good for the rest of my body. I appreciate this mattress has different firmness for different parts of the body. It seems to be working for me as I have been sleeping on level sleep mattress for three weeks and I have experienced good sleep and ZERO back pain. This is a welcome change from previous mattresses. On this particular mattress the sides are not as structured as ones I previously owned. I cannot sit on the edge without naturally sliding off the edge of mattress. Since I chose this mattress for sleeping this issue is just a minor inconvenience. I'm a mostly side sleeper enjoying pain free mornings thanks to this level sleep mattress.
I am so grateful for this wonderful product which provides pain relief for my autoimmune and osteoarthritis joint problems. I am now having a restful night's sleep and can more comfortably get out of bed in the morning. My quality of life has been greatly improved. Thank you to Zach for arranging to send it and the wonderful restore pillow to me in Melbourne Australia. My best wishes to all in the happiness team at Level Sleep. Christina Castles.
Great customer service. Delivery and packaging was easy. Mattress had no off gas smell at all. The cover is so high quality and breathable. Best nights sleep in over a year. Starting to see improvements in my neck and back pain after 10 days on it.
Before we purchased our mattress we had a couple questions about the product so we contacted the company to get more information. They responded right away and answered all the questions that we had. The were super friendly and informative. We purchased the king size mattress and have absolutely fell in love with it. My husband has back issues and this mattress has helped him tremendously! I recommend this bed to anyone looking to get an amazing nights sleep! It is totally worth the investment!
This bed is phenomenal. A must for spine care experts and their patients.
Recently bought a Level Sleep mattress when it was time to upgrade and we love it. My husband, who is an airline pilot, is sleeping better than ever. Just wish we'd bought them for every room!
Love the new mattress. It does what you said it would do - support the spine in the midsection and softer places for shoulders and hips.
I have a chronic lower back pain so I tried several other options before Level Sleep. And I can surely say that Level Sleep totally works for me. This is the first mattress which really relieves the lower back pain. I feel better even throughout the day. Thank you! I didn√¢‚Ç¨‚Ñ¢t think this was even possible.
I now have a total of three Tri Support Mattresses in my home and we love them! We were introduced to this product through a family member and at first we were skeptical and then when we received our first one...we were sold. We have had our mattresses for a few months now and there is no going back for us. Thank you Levelsleep!
We love the bed. My husband said this is the most comfortable bed he has ever slept on.
Both my wife and I were suffering from various pains upon waking every night. Since getting Level Sleep's premium mattress, we both have been waking up pain free. We love it! Thank you, Level Sleep!
I'm 92 and with the help of a 65 year old we had no trouble getting "THE BOX" up a couple stairs and on the bed. That was a couple months ago and so far we're very happy with the purchase.
And then my body adjusted to having lumbar support and my back thanks me every morning!
After the first night of sleep on my TirSupport mattress my back pain decrease by 80% when I got up the next morning. I am hoping that once my body adjusts to the mattress that my back pain will be eliminated.
I've been seeing my chiropractor for about a month with a back problem that was causing pain in my leg. After mentioning that I was having trouble sleeping because I couldn't find a comfortable position, he suggested looking at the Level Sleep mattress. After looking it over, I called with a few questions and ended up ordering a new TriSupport mattress. When it arrived, it was actually kind fun unpacking and setting it up. We've been sleeping on it for almost two weeks now and have definitely been sleeping better with less tossing and turning. My wife even said she thinks we're both snoring less now.
no back issues since Ive been sleeping on the bed- or shoulder issues.....used to have shoulder and neck stiffness in the morning and that is a non issue anymore. I think it would be best to have the special pillow also!
I had a bad shot mattress. I replaced with the tri support and have slept much better from night one. The mid support area is a little to close to the head for my baby. I have a twin. My abdominal part of my body is a litttle longer than normal and my legs area little short. I would have bought the longer and wider one but don,t have thes space.
I no longer feel painful back in the morning. Sleeping on my back seems to be much easier too. I really like it :-)
Very comfortable and good support but my arm always falls asleep if I sleep on my side. Is a less firm version available ?
I have slept better the past week than I have in the last year. The pillow is as much help as the mattress. I plan on getting the pillows for my children.
We started sleeping on our luxe mattress 2 weeks ago and couldn't be happier! We previously had a different brand foam style mattress that cost quite a bit more and we are much happier with the Level Sleep product! Thank you JJ and Zach for the awesome service!
I have questions and I want to speak with Zach. 213.595.5478.
So far so good I think it's a keeper
...a great night's sleep! This topper is amazing. From the very first night we slept on it, we were amazed how comfortable we were compared to previous nights. It arrived promptly and love that it was guaranteed to make us happy. It sure does. Highly recommend!
The TrSupport Mattress is great! We wake up without back pain. It's just the right firmness and it's really fun to sleep on; raise your head, raise your feet and use the wave to relax awhile before sleeping. Thanks to the technology team for the development of Level Sleep mattress bed. This mattress is made with high grade materials and will last a long time. We may go back and buy the mattress TriSupport Topper for days we want a change of pace to pamper ourselves. We recommend this bed to anyone who wants to Sleep Happy. Thank you.
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.
