Serta iComfort has been a favorite mattress of mattress big-box stores and traditional marketers for years. But is it worth the hype? This mattress combines both memory foam and mini innerspring coils.
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.

If you are considering one of these mattresses, make sure to read on for more information. Unfortunately, not all customers give them good ratings. Some folks were cozy in their new mattress, but others reported trouble getting comfortable.
A supportive mattress is the secret to having better spine health. If you aren't supported by your bed, a mattress that does better would mean a much deeper sleep for you. All in all, these mattresses do offer good support at first, but some had issues with lasting comfort.
Most find the edge support that these mattresses provide to be good, which is beneficial for those that like rolling over towards the side of the mattress at night. Those that are heavier may still experience some declining around the sides of the mattress.
Having a mattress that lasts is one of the most important factors to sleepers. We all are hopeful our mattress will last a decade or more and stay just as cozy as day one. Sadly, not everyone has experienced great durability with these mattresses specifically. If you are considering purchasing as your full time mattress, read over the specs and policies to make sure it will work for you.
Some sleepers report that these mattresses are comfy., but others have not been as comfortable with them. Sleepers were mostly positive, but there were some negatives that they described. Read on below for added information about how they work for folks to figure out if they will work for you!
Most customers describe these mattresses as having above average supportiveness, which is ideal for those that are suffering from a sagging mattress right now. That said, some reviewers have mentioned support issues in reference to their bodies, so do some extra research to ensure that your choice works with your body.
Edge support is a mesaure of the supportiveness along the sides of the mattress. These mattresses have good resistance, but some may exerience some dipping along the sides.
Customers gives these mattresses mixed reviews on lasting comfort. We all want to find the perfectly comfortable durable mattress that lasts over 10 years, but sadly not all mattresses last a long time. If you are thinking about buying a new mattress that isn't an A+ on durability, do a double-check on the trial and warranty policies and price to make sure that you are comfortable.
Purchased an iComfort-Applause II King mattress and split box spring. It was ok for the first 6 months, then support degrades after that. I suffer from back pain so the i-Comfort Hybrid series in firm (Fundamental model) seemed like an ideal replacement for my 10-year-old inner spring Sealy mattress. Eventually you'll sink into a hole as the memory foam upper doesn't hold up. My partner and I now have a 'hill' down the middle of the mattress that limits your sleeping space to your own body cavity hole. I had Raymour & Flanigan's inspector come out used their measuring tools to come to the conclusion that the bed is not defective and is within the warranty allowances. Yet I continue to sleep in my confined hole and am now considering taking this POS to the dump and eating a good amount of money. I've filed a BBB complaint and Consumer Affairs report. Raymour & Flanigan is no help whatsoever! I do NOT recommend either R&F nor Serta. Very bad service. The inspection process was such a waste of time. I spent $1,650 on this set and it's barely a year old. Don't fall for the 100-day satisfaction sleep guarantee because 100 days is not nearly enough time to give a true assessment. I'll never buy another Serta Mattress since they obviously don't care to stand behind their claims that i-Comfort Series is 'revolutionary' and is worth the good money I paid for it. Don't fall for the Consumer Reports review that gave it a shining review. This experience has shown me that CR is no longer a good source for researching products before I purchase.View More Reviews
I developed an allergy to the I-Serta foam mattress 3 to 4 weeks after the mattress was delivered. The allergy started as a slight itch and has progressed to the point that I cannot sleep on the mattress. I am investigating zippered plastic covers to encase the I-Serta mattress to see if that helps. If the plastic cover does not work I will have thrown $1,800 down the drain. I am very disappointed with Serta.
Based on my experience the I-Serta foam mattress is not safe. There are ingredients in the foam that off-gas and are dangerous to your health and welfare.
(I swore if this mattress worked out I would write a review because online mattress reviews are so erratic.)
I did all the research and have experience with memory foam benefits, just never bought a foam mattress due to price. I settled on iSerta Savant II for comfort and price. I was concerned once I got it - that it would sleep hot (I sleep very warm) and not do much for joint pain.
It had very minor gas offing initially, but that was gone in 24 hours. The first couple nights I slept on it- it didn't feel as soft as in the store and my back was a little stiff - but my joint pain (hip) was gone and I did sleep cooler. I hung in there and purchased a Pinzon Plush Mattress Topper (Amazon) which added surface softness. After sleeping on it about 3 nights, the back stiffness was gone and I truly can report zero joint pain and a cooler sleep. I sleep noticeably cooler, not zero heat, but cooler. Slept terribly hot in my previous Sealy Oaks Reserve (8 years)) coil mattress. The iSerta mattress is soft, but supportive, like memory foam should be. I have no problems feeling like I am stuck in it and I LOVE the zero motion disturbance - doesn't feel like the mattress is moving around with you. I am a 65% side - 35% back sleeper, so if you are the same, you can feel safe considering this bed. Definitely not for stomach sleepers.
TempurPedic Cloud Lux felt even better, but was $1,700 more than iSerta and felt like a warm sleep even in the store. You really have to pay attention to your body's reaction when you test any mattress. You'd be wise to spend substantial time in the bed, even though it kinda feels awkward simulating your personal sleep positions for all the public to see - in a mattress showroom. (LOL). I have to say that my friends have had a TempurPedic for 11 years now and still love it for comfort, but report that it does sleep hot. They are not natural warm sleepers so that's OK for them.
I can't speak to longevity for this iSerta, but after a month - I am quite pleased and crossing my fingers that will be the case for many years. (I'm still scratching my head that this foam mattress sleeps cooler than my previous coil mattress, as coil mattresses are supposed to sleep cooler and that very fact deters people from buying foam...odd.)
So good luck with your mattress shopping and I hope you get the one that is right for you. For me, waking up with no joint pain (hip and shoulder) and sleeping cooler has been a Godsend. Nighty-night. 😴
Breaks down really fast. Junk save your money. Unless you don't like to sleep then buy one.
We purchased an iComfort mattress in September 2012, and it is already broken down. Much over the 3/4" allowed. We had a rep look at it as there is a fabulous 25 year warranty. Unfortunately, the Serta Company does not play well with customers. One of the two tags were missing, (not removed by us), and for that reason they will NOT cover the warranty. Funny fact.... that this mattress hasn't even been in existence for longer than their warranty. Makes me sick to my stomach that we have thrown away $1800 for a bed that we had just a little over 3 years. In my research, they also do not abide by their warranty if there is a stain, no matter the size. Truth be told, they will do anything to not cover your mattress under their "fabulous" 25 year warrant. Beware, and shop around unless you don't mind paying $40 per month to sleep on a mattress.
Bought my i-comfort matress for a whole lot of money and it didn't last 3 years, Serta didn't stand by its product and should be ashamed to lie to consumers and even hint at a 25 year warranty. They know VERY WELL there is no chance their product can last that long.
If you try and go through their warranty process BE WARNED. They will make you pay for an 'inspector' to come and evaluate your mattress. Unknown to you, the 'inspector' has one job "TO PROVE THAT YOU VOIDED THE WARRANTY SO SERTA DOES NOT PAY". They actually made me pay 40 bucks for a guy to come to my house and claim that my mattress was sinking because of a mark from a pen. Really a lot of nerve. I spoke to a former Serta employee and was even told that THE INSPECTORS MAKE BONUSES WHEN THEY VOID YOUR WARRANTY. Serta will tell you "well they are independent" but guess what? Serta doesn't let the CONSUMER pick the company. THEY PICK THE COMPANY. So they only pick inspection companies that agree to their deal, kick backs in return for blaming the consumer.
This thing will absolutely not last you. Look at other ratings of icomfort mattresses and you will see a pattern, it sinks after months and leaves you with terrible back pain.
Trust a local company and trust only two sided mattresses. Serta knows there is no way one side of a foam matress can last 25 years, even so they go cheap and only put memory foam on one side. Meaning uneven wear and a low quality product that won't last.
READ THE FINE PRINT of the warranty...you're going to see what I mean!
I look forward to laying down on this thing. It is very soft, but in just the right way. Seriously, sometimes when I'm just walking by I go touch it just because it makes me feel good. I can't attest to its durability (we've had it about a month), but it's very nearly been worth the thousand bucks we spent already (we got a heck of a deal here.)
This mattress is not cheap, but we shopped around and it compares favorably to the $3000 to $5000 mattresses at the over-priced mattress stores. Conversely, it is miles better than the bargain $500-$700 "memory foam" mattresses. To get that real, honest-to-blog memory foam experience, you do have to spend a bit of cash, and this mattress is the real thing without being ludicrously expensive (even if you pay full price.)
Now excuse me—I have to go roll around on my mattress for a few minutes before dinner.
I have slept on this for about nine months. The softest mattress I've owned, but a lot less back pain for my husband and I do sleep well. My only criticism is, despite design attempts to produce a cooler foam mattress, the I comfort sleeps warm so four not five stars. I am in Florida, not sure this would bother me in the Northeast. Also the foam is HEAVY. No way I can flip on my own. So if your a women who regularly flips mattress, bear in mind foam is a heavy choice. But you'll sleep.
Great mattress for the first 6 months, then support degrade after that. I suffer from back pain so the i-Comfort Hybrid series in firm (Fundamental model) seemed like an ideal replacement for my 10-year-old inner spring Sealy mattress. Eventually you'll sink into a hole as the memory foam upper doesn't hold up. My wife and I now have a 'hill' down the middle of the mattress that limits your sleeping space to your own body cavity hole. I had 2 different inspectors come out from Serta and they both used their measuring tools to come to the conclusion that the bed is not defective and is within the warranty allowances. Yet I continue to sleep in my confined hole and am now considering taking this POS to the dump and eating a good amount of money.
The inspection process was such a waste of time. I spent $1,650 on this set and it's barely a year old.

We owned the Serta Prodigy II iComfort mattress less than a year when it started developing holes that we were sleeping in. We were both waking up with back pain and I developed a hip problem which has now turned into some very bad sciatica. I can no longer sleep on it. We paid about $2100.00 for it at Godby Furniture. When we complained to them they had someone come out and look at it. It was determined to be defective and luckily we are getting a replacement. I'm so disappointed in this and now I'm afraid by getting a replacement it will do the same thing and then nothing will be done about it. We have had an iComfort before this one for about three years but never had an issue with it. Our son now has it and it's fine. I feel it's just this Prodigy model. Please Serta take note!
Wonderful mattress! Feels like I'm sleeping on a cloud. I would definitely recommend. 💯❤️🔥
After researching the market and CR reviews I decided on the Serta Savant III with Ease Adjustable Base. Memory Foam Showplace through amazon had the best selection and pricing for this combo. Ordering was easy, follow up was excellent, and delivery went smooth. The base and mattress arrived in separate packages and sere carefully loaded into my garage. The driver even helped get the heavy base box into the house. Set up was simple and the full bed turned out great. This is a comfortable bed with a soft feel yet provides firm support. I highly recommend Memory Foam Showplace and the Serta mattress and adjustable base combination.
It felt great when I tried it out in a store. I started getting lower back pain within a couple of days of use. It started to get very painful after about a week. I moved to another (firmer) mattress in my house at that point and the back pain cleared up. It came right back as soon as I moved back to the Serta Savant III Plush. The lower end sinks further than the upper end. The resulting slope puts a lot of strain on your lower back. The slope (and resulting back pain) gets significantly worse when my wife is also in the bed. I tried a few different positions and pillows that did reduce the pain, but not enough to prevent me from needing to buy a new mattress.
THIS SH*T IS UNDEFEATED. It keeps me cool and cozies while wrapped in pretzel legs with my wife. I'd say the only downside is any room this mattress isn't it is now useless. Pretty much go to work, come home, Bruce All Mighty myself out of my clothes and bounce on this cloud of joy and starfish all up on this bed made of 1,368 adorable puppies. Put on the mattress cover to keep it clean from the 67 hours a week you'll be on this warlock. It's basically fixed my irregular sleep, my restlessness, and practically gave me advice on opening a Roth IRA. They included two pillows that aren't nearly as nice as the mattress but they're nice to put between your knees while you dream about dreaming about walking up just so you can go back to bed. And that's not even the best part, folks. Every time someone comes over to your house they'll want to sit on it and demo that fluffy stuffed goodness. Like I said before, the living room is a ghost town. This mattress is perfect for dinner parties just as much as it is a magic carpet ride in the form of a memory foam that hugs you like your chubby aunt without the smell of smoke and Un-Custables.
Wish I would have seen these reviews before I purchased a $2,100 Serta iComfort memory foam mattress. What a POS. I cannot believe they sell this junk. Sleeping in a 'hole' cannot roll out. Sometimes I feel trapped. Please do not purchase this product!
We were so excited about our iComfort mattress when we first purchased it. It was so comfortable for the first few months and then, I began to notice I was waking up in the morning with severe low back pain. I didn't realize at the time how the mattress had actually broken down, and the indentation in the bed where I had been lying. I finally realized that as I was lying in bed, I was lying in a hole. I weigh all of 105 pounds. This mattress has continued to break down and deteriorate. The day I went back in to the mattress store to ask if there had been any complaints with this mattress was actually the 2 year anniversary of our purchase. I was informed that the mattress I had purchased had major problems that had been reported.
I have endured severe pain, pain management including epidural injections over the past months, and then I realized it was the mattress that we had purchased to help promote our good health, and a great night's sleep. Also, the pain has been so bad first thing in the morning, when I first wake up. Instead of feeling refreshed, I feel severe pain in my low back. I have photographs on and off of this mattress to prove the deterioration of this mattress.
The mattress is very comfortable and I wake up feeling refreshed. I would recommend this mattress to anyone. No backache or leg pain. I chose the firm mattress because of my back problems and believe me it helps. Are you needing a mattress that makes you feel refreshed and not waking up grumpy? Then go for it! You'll be glad you did.
We purchased a Serta iComfort mattress in March 2013. It is now sagging on both sides with a huge lump in the middle. My husband can no longer sleep in the bed as he wakes up in agony each morning from back ache and I now have back problems too. Never had a back problem before. Will see how we go with our local supplier - paid nearly $5000 for the ensemble so hope they honour the 10 year warranty. Will never buy a Serta again.
I've tried several brands over the years but Sealy has been truly consistent when it comes to a quality mattress. Always good support (I've got two crushed vertebrae in my back + a crooked spine). Love this brand. Quality made, doesn't fray or unravel. Will straighten out your back which will help with chiropractor bills. Recently strained my back lifting a heavy suitcase. I was a guest in a friend's house she had the worst mattress (she bought a $100 foam topper for it). The topper was OK for 2.5 months then it died - total waste of $$$. I then rented a hotel room with a very good mattress (Sealy of course). I was in agony & it took 12 days of sleeping on their mattress to finally feel better. HINT: Shoes can also cause back problems so pay attention to the soles & heels. Buy new shoes if necessary.
Miserable nights sleeping on this new mattress. I wake up with so much pain and feeling exhausted instead of rested. When using the adjustable head raising the mattress bunches up badly. After paying an inspector 50.00 after only 6 months usage he naturally reported nothing would be done as he didn't find anything wrong. He was in bedroom a total of 7 minutes. This is going to be costly for me as I am an 84 year old widow on a very fixed income. And no one at the mattress store cares about my problem.
I've had my iComfort adjustable bed for two years and over time I have become increasingly sick when I sleep on this bed. I have chemical sensitivities so I bought a cover for the mattress, which has helped. However, I found myself coughing throughout the night and waking with a sore throat and headache. The brain fog and fatigue are getting worse, so I started sleeping on a relatively new mattress (not memory foam) in my guest bedroom and even tried the twin mattress on my daybed. I have not had any problems with these health issues when I avoid the iComfort bed. It has taken some time before my health issues became severe enough that I could no longer blame it on "just my allergies". I will be getting rid of the bed and I paid a lot for it. BTW, I just don't use the adjustable feature, but I really don't spend a lot of time hanging out in my bed. I'm very disappointed in this bed. If you have allergies or chemical sensitivities, do not buy this product!
We were so excited to get this incredibly comfortable Simmons iComfort mattress only 3 years ago. It was all hype! Both my husband and I are currently suffering with back problems. As we stepped away from the bed when changing the sheets, we noticed how much it sagged and realized the indentions that remained. The warranty is based on the small number "Warranty Code" that is printed at the bottom of the "UNDER PENALTY OF LAW" tag that everyone tears off and throws away after they are sure they are going to keep a product! I will never purchase another Simmons product again! For this kind of money I could buy a new mattress every year for 3 years.
So i get i am likely writing this too early, but let me tell you this is literally the best mattress i have ever slept on. My boyfriend is feeling the same way. No kidding, this mattress is the perfect firm but with cradling comfort. I drooled for the first time since i can remember. I am going to have a love affair with this bed. Never got hot, never god sore and had to rotate to my other side or stomach. And woke up without a single ache! I am telling everyone about this stellar mattress!
Good mattress for the first year or so, then support degrade after that. I suffer from back pain. The i-Comfort seemed like an ideal replacement for my 10-year-old inner spring Sealy mattress. Eventually we put a topper on the mattress. Now we sink into a hole as the memory foam upper doesn't hold up. My wife and I now have a 'hill' down the middle of the mattress that limits your sleeping space to your own body cavity hole. Seems a waste of time for inspectors to come out from Serta since no one else has had success wit them. Yet I continue to sleep in my confined hole and am now considering taking this POS to the dump and eating a good amount of money. We spent over $2,000 on this set and it's barely 5 years old. Don't fall for the 100-day satisfaction sleep guarantee because 100 days is not nearly enough time to give a true assessment. I'll never buy another Serta Mattress since they obviously don't care to stand behind their claims that i-Comfort Series is 'revolutionary' and is worth the good money I paid for it.

This is absolutely the worse mattress I’ve ever tried to sleep on.Only had it a few months and it’s killing me ,toss and turn all night and can’t get comfortable.Its pretty bad when you can sleep on a motel mattress but can’t sleep on your own. I get up sore and feel like I’ve been fighting all night,lm looking at other mattresses but don’t know what to buy ,I don’t think any of them are any good and you pay a big price for them.Im really disguised!
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.
