We all want a mattress that will last for years, but due to viral marketing and too many options to count, it can be difficult for shoppers to get the right info. That said, the data on the materials used, tests performed, and customer reviews can be a good guide to estimate longevity. These mattreses last for more than a few years for the average customer. Some who are larger may find their mattress to be less durable.

Mattresses don't last as long as they used to in years past. Finding a mattress that remains really comfortable after 15 years of use is definitely not a simple thing. But, finding a mattress that really is cozy for a long time can save you lots long term. Unfortunately, customers give these mattresses mixed reviews on durability. Many sleepers don't report issues, but others have complaints about durability over a shorter time frame than usual.
I was a little hesitant in buying this mattress not knowing how it would feel. But I went for it and am now recovering and sleeping the best I ever had! It’s a must buy!View More Reviews
We can’t say enough good things about our purchase! We both sleep great. And best part...no more lower back pain for me.
Absolute best mattress and pillows I’ve ever experienced (68 years)
I was a little skeptical at first, because it came in a box. Don’t be fool. Best decision ever. Set Up: Super easy. Be careful when cutting the bag so that you don’t cut the mattress. I just wished it gave a hint as to “this side up.” Support and Comfort: Right Firmness. The mattress targets certain pressure points on the body. I did an 18-mile run, laid in my bed and noticed how relaxed my feet were. My recovery time was seamless. Cost: It is pricey, but it is so worth it if your workouts are intense throughout the week. There is an option to purchase the mattress through credit and pay it off by installments Sleeping pattern: Wow! I have been able to sleep my full 7-hrs. Rest is key.
I have to say was very sceptical but it has been awesome
It had been at least 12-years since I’d purchased new mattress, so looking for a new with all these different types of mattresses was going to be tough! After extensive research and reading reviews; I bought my performasleep King mattress! Well needless to say it didn’t disappoint. Great mattress and from the moment I laid on it; I felt my body just starting mold into the mattress with all support it needed still!
This mattress has brought sanity and sweet, sweet slumber to our lives. We feel the need and urge to tell all our family and friends about it. It has been a blessing for sure!
I haven't felt so happy about going to sleep before my matress arrived. Help my lower back pain significantly. Very happy.
Absolutely the best sleep I’ve had in my life, through my marine corps career and now a veteran with back shoulder knee and other problems I’ve found a bed at least for now which satisfies my needs. Excellent job.
I love this bed. Such better sleep at night. I should have gotten pillows to match!
I've been sleeping on my queen size mattress for a week now and have been extremely happy. I wake up well rested and feel refreshed. The perfect combination of firmness and comfort. Great bed!
The mattress has changed the quality of sleep for both me and my life. We both feel like we have better quality sleep
I bought this with some skepticism because of all of the differing models out there. I have used this for two weeks now and its great. It shows me just how much I needed a new mattress. Getting great sleep and not waking up with a sore lower back anymore. Worth the investment . JH
Cannot until it arrives
Best night's sleep in years!!!
First time sleeping in a foam mattress. I thought it would feel mushy and hot. But its actually comfortably firm but not too firm and not too squishy. I also thought it would be hot. It feels comfortable. It doesnt get too hot or too cold. Back feels better too!
We've been sleeping on the mattress for about a week now and if it holds it's current firmness I will be very pleased with it. It's a really good combination of softness and firmness.
Great products and great service!
Extremelly happy with my new mattress. So comfortable and no back pain. Love it!
I had problem with my old mattress and would wake up with lower back pain all the time. This mattress fixes that problem. I’ve been sleeping great since I’ve bought it and have not been nearly as tired in the morning when I wake up
We were on a search for a decent bed that was affordable for a good year. It came down to choosing a box mattress but it's so difficult choosing a brand! Ultimately we choose this mattress because my wife competes in Crossfit competitions and Spartan races and she liked the idea of a mattress to play a role in her recovery. We are now both sleeping better at night with no tossing and turning and seem to wake up more rested.
Thank you for making an affordable quality mattress! Worth Every Penny!
I have had the bed for a couple of weeks and it has preformed as advertised.....and I am very happy with the purchase. I have had no lower back pain that I used to have after sleeping on my old conventional mattress.
I’ve never slept Harder or Better on this thing! I used to snooze for hour or two every morning, now I’m rested, rejuvenated and excited to get up at my first alarm and get to my morning workout.
We love this mattress. It shipped quickly, easily set up, and sleeps great. Highly recommend!
We received our Performa sleep mattress a couple weeks ago and so far we are in love!!
Been sleeping on a king size for a week now, I’m a severe Sleep Apnea case and haven’t had a dream I could remember without wearing a CPAP for a very long time. That changed last week when I got a Performa...I’ve constantly woke up this week and remembered having vivid dreams. It’s kind of nice knowing I’m actually falling into a state of better rest. Getting back to training this month and can’t wait to see the improvement while recovering through better sleep. Seriously, considering a purchase of the pillows offered.
This is the most comfortable mattress I've ever slept on in my life. I lie down and don't want to move. This is the only bed I've ever been able to sleep on on my back. It is definitely cool. My fitted sheet feels almost cold to the touch. I haven't gotten overheated at all. I was able to carry the box to my bedroom and unpack it myself (full size) Such cool packaging! I did that in the afternoon and it was perfect at bedtime.
Noticed a big difference in my sleep the first night we got the mattress. Didn't wake up once during the night and the copper infused pad helped keep me cool all night. Can't imagine sleeping on another mattress.
For years I’ve had trouble sleeping and waking up feeling rested in the morning. I’ve been sleeping on my new PerformaSleep mattress for 9 days and I’ve already seen a drastic improvement. I wake up much more rested and without back pain. It’s been years since I’ve felt this good. Thank you PerformaSleep for an incredible product.
Bought a Queen mattress a year ago and had to buy a king because we just needed that much more amazing!
The mattress arrived very quickly and was a snap to set up. It is extremely comfortable. I am glad I made this purchase.
I purchased this bed based on reviews and not sleeping well along with waking up sore because of a crappy mattress. Now that my body has become used to the performa sleep mattress I sleep great and wake up feeling rested and never sore. Also, it was incredibly easy to unpackage and start using.
What a great bed! It exceeded my expectations!
After the first night I wondered why I had waited so long to switch to PerformaSleep! I have spent my adult life with back pain and pain in my hips from sleeping, since I've had my PerformaSleep mattress I've been pain free. I expected an adjustment period because I've spend my whole life on a traditional style spring mattress but I had zero issues adjusting and from my first night I've been sleeping better than I have for years!! And customer service, top notch. They responded to an email within hours, on the weekend!! Thank you PerformaSleep, I recommend you to everybody that will listen!!
Have had this mattress for a two weeks now and no complaints. I'm actually getting less hours of sleep but waking up more fresh. I feel it's definitely helped my recovery also.
Love my new mattress and let’s not forget the pillows!!! Best pillows ever!!! You guys are the best, you really care about your product and making you customers happy!!! 100% recommended... I’ll definitely change all the mattresses in my house...
This is not a super soft pillow top mattress. This is a mattress for an active individual, it is firm allow your muscles the time need to relax and recover. If you are used to a softer bed give this mattress a few week and you will feel the difference. Great Mattress!
Happy with my new bed
I received the pillow first, and my boyfriend instantly fell in love with it. A few days later the mattress came, and I haven’t slept this great since I can remember. It’s truly amazing. Oh and my dog and my boyfriend fight over the pillow. We definitely are very pleased with our purchase!
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.
