Sealy

Sealy is one of the most recognizable mattress brands in North America and globally. As a mid-grade brand of the Tempur-Sealy conglomerate, they are well-known for selling competitively priced options in a variety of designs, like all foam and spring. Sealy is intriguing, having adapted its brand from in-store only to also offering online choices. With many firmness options, most customers like their Sealy mattresses, but there are some durability complaints reported.

Serta

Serta offers foam and coil mattresses and are common at many mattress stores and big box retail locations. As a household name in the mattress industry, Serta has been in the mattress business for a long time. Their mattresses range from budget-friendly to higher in price and offer a variety of firmness options and cooling designs. While most customers find Serta's branded products to be initially comfortable, there are some concerns about durability for some sleepers.

Sealy's Owner Satisfaction

Sealy offers a wide range of mattress options, including all foam, innerspring, and pocketed coil type mattresses. Over the years, they have been most famous for their Posturepedic brand that focused on zoned support. However, over recent years, they have focused on budget-friendly options. In spite of them being a household name and having a wide selection of mattresses in different firmness types, there are many sleepers that have complaints about these mattresses. Some of the complaints have to do with sagging and initial comfort. If you are heart set on a name-brand mattress, consider Sealy's Cocoon mattress, which has transparent reviews and is better rated by customers than other Sealy mattresses.


Sealy's Supportiveness

Finding a supportive mattress can be a struggle. While Sealy has a selection of firmness options, even firm mattresses may degrade in support or not support the spine ergonomically. Sadly, Sealy's selection has some mixed reviews when it comes to support. Most find that they provide a good amount of support at the beginning, but some folks felt like support was lacking over the long term.

Edge Support
For those with mobility concerns or like to lay close to the side of the mattress, edge support is very important. Sealy has paid attention to edge support over time, but softer mattresses (especially foam options) may not be supportive enough along the edges for all sleepers.


Sealy's Durability

We all want a mattress that lasts 10 years or more, and when our mattress causes us back pain after only a few months, we feel terrible. However, finding lasting comfort nowadays is a real challenge. With more companies than ever, companies fighting for profit at the demise of quality. When it comes to these mattresses, some sleepers had issues with durability on some mattresses -- generally the more affordable and softer varieties. Durability issues don't happen to everyone, but if your focus is long term comfort, consider taking a look at our list of top rated mattresses for competitive alternatives.

Serta's Owner Satisfaction

Alike to Sealy, Serta offers a wide selection of mattress types. Their iComfort brand is one of the most popular, with layers of gel and memory foam layers. While many folks were very pleased with their mattresses at first, others had issues with getting comfortable. Disagreements ranged from those that had heat retention and firmness issues to durability problems. Against Sealy, both have significant complaints.


Serta's Supportiveness

In terms of providing comfortable support for everyone, these mattresses get mixed reviews. Some feel like the mattresses provide good comfort, but others didn't feel comfortable while they slept. If you have a wider or heavier frame than average, support may be an issue over time. Though, Serta does a good job providing a range of firmness options, some found that supoort degraded over time.

Edge Support
Edge support is an important item for anyone that likes to lounge on the side of their mattress or has mobility concerns. Serta has focused on edge support in their mattresses and many find them to be comfortable, but some customers have found these mattresses to not be entirely supportive. This is more widely reported on their all-foam varieties.


Serta's Durability

Though many feel comfortable at first, some sleepers found these mattresses not to be as durable over the long term. Some sleepers have had problems with feel and durability over a shorter than average time. If you are larger or are looking for something supportive, one of these mattresses may provide initial comfort, but do a last check on the mattress specifications and return policies before purchasing. If long term comfort is an essential, consider taking a look at our list of top rated mattress for competitive alternatives.

It really is a top quality innerspring mattress. It REALLY is!
I did a lot of research before buying this mattress. The deciding factor was the recommendation of Consumer Reports. When I first received this mattress, in a square box, I was soooo disappointed and upset. I attempted to return it before opening it, but realized how expensive shipping would be. I returned to the website and their were no reviews but I searched some other mattresses with the same features and price points and discovered that it would, when unfolded, rise to it's full 12 inches and it did indeed have cloth covered coils (innersprings). It Did rise, and then some. I think it's about 13". Very comfortable, everything Consumer Reports said it would be. It's a little firmer than I would like it to be. It's not hard by any means, in fact it's quite comfortable and very good for my husband's back, he likes it a little firmer than I. after putting a good quilted mattress cover on, it added just the amount of plush and squish I love. I get a good night's sleep and wake with no stiffness or aches. I really like it.

Good matress
Excelent matress, I wasn't sure to get it for my daughter since it didn't have any reviews but after a month of using it, she loves it, firm but comfortable; stays cool and no more joint pain.

Do not buy this !
We bought this mattress 2 3/4 years ago and I've been having chronic severe back pain for over a year. I had noticed that the bed definitely sinks in the middle when I lay on it and I'm a hundred and fifty pounds. We've only had this mattress for going on 2 years & 9 months. We loved it at first, until the past year. I didn't attribute my back pain to the mattress until I slept somewhere else and my back pain was considerably better. Everyday when I wake up after sleeping on this mattress my back hurts more than it does all day. My boyfriend has been sleeping in the basement on the couch because of his work shift for the past 4 months. When he sleeps on his mattress on the weekend he says his back hurts too. I just submitted a warranty claim, but have a bad feeling that I'm going to get the runaround from the reviews that I've read.

... of metal coil and 4 inches of foundation nothing like I was expecting a
This matress is inches of metal coil and 4 inches of foundation nothing like I was expecting at all

Sleeping Great
My old mattress was very soft, in comparison this one is a rock, but I don't wake with the same sore spots. I have arthritis through out my back, shoulders, hips, etc but I'm sleeping better with this Sealy.

1 year later and I would certainly buy this mattress again.

sweat factory!
Mattress is about 1yr 4m old and is terrible! It's well worn and sagging where I sleep and the amount of heat the 'cooling gel' holds in is ridiculous! I sweat all night long and wake up drenched. I wash the sheets almost every day now. I don't know what we were thinking when buying a foam mattress. When you squish foam it seals up all the holes in the foam eliminating it's availability to breathe! No brainier if we would have thought about it. Skip the foam it's not worth it!

Was worried that it was to good to be true
Was worried that it was to good to be true.not a single thing wrong with it and it's absolutely wonderful to sleep on.saved us over a thousand dollars.

Soft bed, very comfortable but not for me
I bought this bed from another place and thought I would give it another review to help others out. First off I'm a bigger guy who is a furnace in bed with lower back probIems. I spent a month in the bed to give it a chance but ultimately had to take it back. It was soft enough to be comfortable and fall asleep in easily. Around 3-4hrs in I would feel my back slowly be unsupported and I would bottom out to the foam base layer due to my weight and the heat I put off would cause it to soften. I noticed though before my back would be unsupported I would sleep deeper and easier. My fiance is a belly sleeper and the softening would cause her minor back aches but she had liked the softness and comfort too. The bed felt as warm or a bit warmer as a spring mattress with a topper on it but a lot less hotter than a memory foam without gel. There wasn't too much off gassing. Overall construction was good but felt like this was for a lighter, cooler person.

Pretty nice mattress
Love it so far.I've had it for a few days and wish i would have done it a bit sooner.maybe is just me coming off an old futon 😝 but it's definatly plush but still firm

TRASH!
If I could give this matress 0 stars I would. After one month I noticed a moldy smell around my bed, I pulled my matress cover to find the smell coming from all over the matress. It's not chemical, think mold dish sponge. It's also sinking by bout 1/2 an inch, I weigh 160 lbs, that's after 1 month.

You can assume that any good sealy review is a plant/fake review. sealy is a trash company that makes trash products. I'm out $550, have no bed to sleep on, and couldn't be more furious. BUYER BEWARE!

Wasn't intending to get a foam matress, but...
I am 6'3'' and weigh 220 pounds. I prefer a firm mattress and have only slept on box springs my whole life. I am a side sleeper exclusively. I went to 2 separate mattress retailers and laid on every mattress on their showroom floor. Both times I gravitated to this mattress. It is the most firm of the 3 Optimum model mattresses. I laid on all 4 of them as they were side-by-side. They got softer and more expensive as I went up the line. I've only had this mattress for a week, so my review is an early one. I had no intentions of getting a foam mattress when I went shopping. I was concerned about comments about them sleeping hot. This mattress does not sleep hot in any way shape or form. The salesmen explained to me that the initial Optimum mattresses didn't have enough cooling gel and they have added more and it has resolved that complaint. I concur. I haven't noticed any problem with sleeping hot. The biggest thing you will notice with a foam mattress is you won't feel any pressure points like a box spring. When I laid on any box spring, I would immediately notice a pressure point on my hip and my shoulder. I don't feel anything on the foam. I have slept just fine for the past week and no complaints of back pain or any pain in the AM. I am impressed so far. Will have to come back on in a few months or a year and comment on how well the mattress is wearing. I have also read comments about this mattress having a odor when delivered. The mattress and the box spring were both in plastic when the delivery people unpacked them and installed them in my bed frame. I didn't have any odor at all, so I'm not sure where that is coming from? I bought 2 of the Optimum pillows which I slept on before my mattress was delivered. They smelled a bit for a few days, but it gradually went away. I did not buy this mattress from Amazon, but decided I would comment on it here after I did buy it. These reviews of all kinds of mattresses are so frustrating. Who is commenting? The company that makes the mattress? The competing company? Disgruntled employees? I am just an ordinary consumer that needed to replace his 25 year old box spring mattress. I've owned 3 Sertas and a Beautyrest. This is my first Sealy. The salesman was telling me that several of these companies have bought out each other, so they are all about the same manufacturer now. I am pleased with my choice so far and recommend you go lay on this mattress if you prefer a firm one. This was the most firm of all the foam mattresses I laid on.

It is the worst purchase I have ever made in my life
I can't believe how much money I spent on this bed! It is the worst purchase I have ever made in my life! I have never had such severe back and hip pain when I wake up in the morning. Do not waste your money on this or Sealy's adjustable (head up only) frame! You can feel the space in the frame when your head is raised through the mattress…terrible!!! I recently spent two weeks away from home sleeping on a cheap mattress and felt so great in comparison to being back home sleeping on my expensive junk!!!

Has yet to get comfortable.
I've had this mattress for 8 months and it has yet to 'break in'. When we went to mattress store, we laid on all of them and ended up with this model. It felt perfect. For some reason, the one we got is like a brick. Both my partner and I are on the lean side, but still.

very disappointed
I bought this mattress on march 15 and the first 4 nights I loved it no back pain and very good support but then I started noticing that although the memory foam always went back to its original form the inner layers of non memory foam on the where getting softer and I no longer had a firm mattress. Im a stomach sleep and this mattress turned onto a nightmare I hated how soft it was and when I was watching tv my bottom would sink in all the way. I no longer have mid back pain like my inner spring but now my neck and shoulders hurt from the rest of me sinking and putting stress on my shoulders. The box spring on this matress is horrible it does not provide any support and the whole motion transfer thing was as advertised for the first week after that i could feel my husband moving. Not as much as an inner spring but not was it was when i first got it well to top it of on the first week of april I called the store where I got it and told them it was sinking and sure enough a tech came and siad it has sunk 3/4 of an inch in less then a month so they gave me the option of getting another one or one for greater or lesser value. I decided to get the tempurpedic contour select it was $1300 more but my parents had bought one a week before I got my sealy and the tempurpedic is still as great as the first day so I didnt wanna risk it with getting anything else. Now im sleeping like a baby and glad I could change it.

Worst Mattress with 10 year warranty Sales Tactics
reviewed on Dec 05, 2018 Purchased Sealy Posturepaedic from Harvey Norman, Warwick,QLD in March 2016. Within two years of use the mattress has sank in the middle, low enough to make uncomfortable even to just lie down rather sleep and cause body aches. Have rotated the mattress periodically as specified but just not durable even though the warranty is 10 years. The warranty terms and conditions doesnt justify for claims. 30 35mm sag is deemed to be normal in their terms. But given the width of the double mattress not much, that sag is substantial enough to cause issues to the body. They claim to use titanium springs for durability in their mattress. but having used for two years it has to be concluded that it is poorly engineered and the quality of their product is compromised for a rip off.

Sagging again!
Put he’s a queen size Sealy from Macy’s in ChicAgo burbs in late 2017. Paid about $1,200 tax and delivery. Started to sag really badly in the middle after 5 or 6 months. I called Macy’s to complain since it’s under warrenty. They sent a technician out to review and look mattress over. The tech measured the depth of the sagg and it was well over 2 inches in the middle. I’m 5’8” and weigh 175. This is a sealy brand but I don’t have a model number. It was on the softer side with a pillow top. My back and hips were sore every morning. Macy’s made good on the warranty and I chose the firmer model as the replacement. Well, 6 months later I’m laying in a huge gully or canyon again. I’m beginning to wonder if these Macy bought models are more low end then high end. Time to call them back and replace number 2.

Poor Customer Service
I will never buy another product from Sealy. I bought a Thermapedic Mattress made by Sealy from Rooms-To-Go. The adjustable base would not raise the mattress within two weeks of purchase. I was directed to Sealy through RTG customer service. The Sealy agent stated that the base needed resetting. She wanted me to go under the bed to get a box to reset the base. When I informed her that I was unable to go under the bed, she told that Sealy does not send repairmen to reset the box. She told me to call her back when I could find someone who could go under the bed. When I informed RTG of her response, a RTG repairman was sent He went under the bed and retrieved the box. He stated that the adjustable base was broken. Resetting the box would not have fixed the problem.

Noooooo
Horrible hard and very thin not even worth what I bought it for

POOR POOR POOR POOR DONT BUY IT
I got the mattress I was highly disappointed. To begin with its a 3 inch mattress. Not happy at all. This was the worse mistake ever. I returned the bed and mattress. Had to take a $125.00 restocking fee and a $50.00 re delivery fee. Plus the only way that I can trade it in was if I bought a new bed so I will take the loss this whole thing leaves a very sour taste in my mouth and I will take the loss the picture above is very misleading. do not buy this product

Uncomfortable mattress. Could never have imagined how terrible it is.
The mattress is so uncomfortable!! Ughhh! Hate it will not keep

Not as thick as it looks but still good
I ordered before the previous review but read said review before my order arrived. So I was not surprised when my order arrived and the mattress was thinner than I originally expected. It looks much thicker in the picture. The box spring is probably double the thickness. With saying that, it is still a good height if not on the ground. The mattress is quite firm but I still go right to sleep as soon as I lay down whereas that was not happening on my old mattress. I would reorder.

Mattress is NOT as pictured.
I ordered this mattress online. Cheap & cheerful... or so I thought. The mattress was delivered today, its smaller (in thickness) than the box springs. The image on this product is completely misleading. The mattress is probably 2-3 inches thick. Completely disappointing & extra frustrating.

Great choice.
Buying a mattress online is risky. However, if you are not physically able to get out and shop, you may have to do what you have to do. I bought this knowing I wanted a mattress with a plush top. I wanted it to be durable and strong enough to hold but when I laid down on it - it was soft for arthritic patients. I love this mattress. I look forward to going to bed and I don't wake up in pain from laying on a hard mattress.

Mattress to soft
The matteress is to soft. I should have ordered a firm

this is a great mattress. it has made my sleeping much better!
Great mattress equals many great nights of sleep! Plus the delivery service was great also.

for what I paid-definitly worth it.
liked how I got a good deal around presidents day.

Nice looking matteress
I had thought I had ordered a firm mattress but a plush pillow top was delivered. I was gone at the time it was delivered at my house, the old mattress & box springs were gone and the new this set was on the bed. So, it couldn't be returned.

To plush
I ordered this bed set on line with out trying it out big mistake. I'm sending it back, its like sleeping on a deflating air mattress. I woke up soar it's just way to soft for me.

Great sleep - Great savings!!
I saved a ton of money of my new Queen Sealy mattress and am now sleeping better than I ever did on one I spent double on!

Great buy
We bought this bed on sale and were not disappointed! This bed is amazing. It is definitely plush and not a firm mattress. The delivery service was outstanding too. They called us often to update us on a time and they were in and out and made sure everything was perfect.

I sleep very well on this Mattress
I sleep very good since I purchased this mattress !

THANK GOD
I have a bad leg and need surgery from a injury 40 some years ago while in the military and this mattress is a GOD sent for my back as well.

Thought this was a great bed
Me and my boyfriend purchased a new bed and we're surprised that after 6 months the quality is horrible the bed is already dented as if the bed was years old. I am very disappointed with the quality of this bed. I will have to do my research more thoroughly next time before I purchase a new bed.

I returned this because I ordered the wrong item
The mattress was as indicated, but I needed the firm pillow top so I returned that mattress and box spring and re-ordered the firm mattress only. It was for my guest room bed that has storage drawers, so when I received both pieces the bed was to high, you need to be 5'6' and up to be able to sit or get in the bed. (:

Excellent Mattress Set
I love this bed. Very comfortable. I would recommend this Bed to friends and family.

I really like this mattress.
My mattress arrived in the time frame that I was told it would come. It is a great mattress.

Amazing Mattress
This was a perfect purchase. Arrived on time, white glove service, and the most comfortable bed I've ever slept in. Highly recommend!!

Too Soft
I would not recommend this set at all it is extremely too soft. It is so squishy that when I sit on the side of the bed to get out, I feel like I am trying to pick up my butt off the floor. It is not comfortable because there is no support.

Well made mattress in firm
I have a tender back and don't wish to sleep on a tender mattress. I found Sealy Essentials Holly Hills Firm Mattress paired with the special box springs saved my tossing and turning to into a great night's sleep. I feel refreshed when I wake up with no back pain or discomfort.

Excellentt value and quality
I purchased this mattress for a redecorated "kid's" room/home office. All of my grandchildren are teens now and the daybed no longer accommodated their growing bodies. I love the quality and value of this product. The mattress is firm, but comfortable, and is an extremely good value for the price.

Really nice when warm. Hard as a brick when cold.
Have a cabin where the bed room temp is around 60 in the winter. The upper 3 inches of gel memory foam is really ridgid when cold. Climb into a cold bed is more like climbing onto a piece of plywood. After about 10 minutes, your body temp softens the foam and it is really comfortable... until you roll over too far onto a cold slab and you are back on the plywood.

I sure hope summer is more comfy.

The Best Mattress!
This is a great mattress! My husband and I moved to our new house and bought this mattress for our room. The first bed that came did not open up all the way and was basically a taco. We called Amazon and they sent a replacement. We have been sleeping on this bed for about 3 months now and we can feel the difference from the traditional mattress we had prior. Our sleep is a lot better, we no longer feel sore, and we don't notice each other's movement during the night. Definitely get this mattress!

Firm enough for a big man like me!
I weigh a lot in comparison to other people so I was initially hesitant to buy a memory foam mattress as I feared sinking to the bottom or drowning. This mattress not only held my weight stiffly but it is super comfortable and probably the best mattress I have ever used. I bought the double and it worked so well that when I bought a king bedroom set I decided to buy the bigger exact same mattress in king size. It come in a big box compressed so you will want to get it upstairs on the bedframe before you open it up and let it absorb all the air around.

Great Buy!
I was uncertain about purchasing a mattress on-line, but the price was so much below what I found in stores that I went ahead and made the purchase. I'm glad I did. The shipping was easy, the mattress quickly expanded once in place. I did not notice any odor. I'm sleeping much better through the night and wake with less back/hip pain. This mattress is a great buy, especially for the price!

Amazing
My wife and I were looking to upgrade our bed to a king during a recent move. We looked at all the big named stores for furniture / mattress and were taken back by the price of the memory foam mattress. We tried out the I-comfort mattress Raymour and Flanagan's and really liked it. After spending hours researching this mattress, I came to the conclusion that this is similar to the Serta I-comfort and about 1/4 - 1/3 of the price. This bed is exactly as advertised and feels identical the the I-comfort we tried in the store. We could not be happier and it sleeps so much better than a traditional spring mattress. I would recommend to anyone.

Remember, you also need a box spring or foundation. This will add another $200 - $400 for the total cost of the bed.

A most fantastic mattress
Our new mattress is comfortable beyond words and so much lighter than the Tempurapedic we had before for many years. It feels like a heavenly cloud and we have slept so well on it and could not be more pleased with our purchase. The price of it is unbelievably low, I recall we paid $2,000.00 for our old mattress over 15 years ago.

Maria & Ted Phillips

I snore less.
One of the best beds I have slept on. I usually sleep HOT and was leary of trying the memory foam bed, but i was amazed at how cool it sleeps. My wife has also said that I do not snore as much.
I could not give the bed a 5 for one reason. I like to sit on the edge of the bed and put on my shoes, but this bed does not have the support on the edges to do that.

Hard, hot, and bumpy
I've had this mattress for 3 weeks now and I am not happy. It is very firm for a memory foam mattress (maybe it will soften up over time), so firm that my body doesn't sink far enough to fill in the lumbar space of my back. I wake up sore every morning, and it reminds me of sleeping on the ground (I camp a lot, so I know). It was shipped in a shrink wrapped container, folded in half, so there is still a noticeable ridge down the center of the bed that divides the two halves. Also, even after airing it out for a week, it does still have a noticeable plastic smell. Lastly, it does trap a heat a little bit.

Overall, I am really unsatisfied, and am contemplating returning it.

Very good mattress
I have had this mattress for a year. The mattress is very good. I read a ton of reviews before purchasing this mattress. A lot of mixed reviews when I researched this mattress. I could not see spending 1500 to 3000 dollars for a similar mattress. I was a little skeptical because this mattress was so cheap. Amazon Prime was a factor in purchasing this mattress. The mattress is very good. No issues with smell or sagging. I am very happy

Hard as a rock
Wow, what a disappointment. Sure wish I'd listened to the reviews that said this mattress was HARD. It's not just firm, it's like sleeping on a stone slab. I can't imagine the hassle to pack it up to return it, so after a week of suffering, we bought a 4-inch memory foam topper, which has helped tremendously. However, as soon as we can afford it, we're buying a real memory foam mattress.

Way to firm for Foam!!
If I had it to do all over again I wouldn't have bought this. It needs to be listed as an Firm mattress. Since I have it, I tolerate it. I went out and bought a 1inch foam topper to put on it to reduce the firmness. What I do find is as you sleep on it and it warms up it gets softer. So I bought a heated mattress pad and put it on also. About an hour before bed time I turn it on low and it does soften the mattress somewhat. Over all I would never recommend this mattress nor would I by it if I knew what I know about it now.

Great Sleep
We were a little worried to buy the bed online, but took the plunge. We were pleasantly surprise at how quick it was delivered. The queen size bed was heavy, but being boxed up made it easier to move. Once in the bed room, we unpacked it and let it return to its original shape. About two hours. The bed sleeps great. My wife and I both enjoy the fact that it adjust to our size. It does not wiggle when I get out of bed at night. I was expecting to sleep hot, but the cool gel works. Great purchase and great value. We priced similar beds at retail stores and they cost $1200. Very happy.

I love this mattress
I bought this mattress almost 2 years ago and I still love it.

That being said, I must disclose that I am somewhat cold-natured, so I don't mind that it retains heat, as the new memory foam mattresses do. This is the only reason this mattress gets 4 stars instead of 5.

When I purchased this mattress, I had done quite a bit of research on prices and quality of memory foam mattresses, and found this one to be one of the most economic choices for the quality. I am happy that I chose this one.

It arrived in a big square box. WARNING: Do NOT open the box until after you drag it upstairs and into the room where you want to use it. Opening the box in another room will create a lot of unnecessary work for you.

The instructions said it would take about 24 hours to completely assume its proper shape and size. In reality, it was ready just a few hours later.

My husband complained that it was not as soft as he liked, so we bought a memory foam/gel mattress cover for it at Costco. This helped make it softer and provided some relief for my husband from the heat retention.

If I had to buy another mattress, I would buy this one again.

Smart buy
The full size mattress is really comfortable. Bigger then a normal full size mattress. We had to replace the old boxspring to a sleep master smart base because of the size if the new Serta. Now we have more room under the bed for storage as well.

Great for sleeping, but quality a bit poor.
I was already to give this a 5 star rating. We bought it in june for our summer place. We have a temperpedic and home and never sleep well with out it. We could not justify the cost to buy one for the summer place. When we found this we were excited! The negative reviews sounded like the negative reviews for temper pedic, so we were not too worried. The box made it really easy to transport ourselves to our place. It opened and inflated great! We had all the windows open and fans going, but we never really noticed an odor. We even slept on it the first night!. It was close to the temper pedic sleep wise. Not quite as cloud like, a little harder, but it worked for us!

This weekend, I took off the waterproof cover that we purchased to wash it with the sheets. I found 4 places on the mattress where the seams were split and you could see the foam inside. Very dissapointing! We expected a little more from a Serta!

Love this mattress
Excellent mattress through and throughout..Amazon was super quick and mattress was in perfect shape..As I sleep on this mattress 2 yrs later all I can say is I sleep like a baby..It feels like you're sleeping on a cloud ..I wake up refreshed from a great night sleep day in and day out..

I'm lovin' it!
Researched loads of beds in my desperate attempt to get a good nights sleep and deep six the pillow top that was aggravating my already ailing lower back...........decided on the Serta icomfort since many people commented on how hot the memory foam gets.....and tried it out at my local store where they were upwards of $1600 depending on the depth. Arrived promptly, NO SMELL, easy set up and was sleeping in it that night....however my husbands initial comment before he had slept on it, was that it was like a slab of concrete.......... but once you're in it this is not the case... It is firm, yet neither too firm nor too soft and extremely comfortable altho it did take me 3-4 nights to get used to it having been sleeping on a pillow top, and I did find I had to adjust my mediflow pillow somewhat so it was flatter and lower...........the only down side I can see, is that both myself and my husband have been lingering in bed much later than normal, I used to be up at the crack of dawn since my back would be complaining and I needed to get up, but its oh so comfortable, and I'm loathe to get up when its so very snuggly and cosy....I'm sleeping much better with less tossing and turning due to pressure points.... if you're considering one, I'd say go for it, we both love it and were not dissapointed in any way!
**UPDATE** Oct. 2014 No sagging....best bed EVER!

Serta 12-Inch Gel Foam 3-Layer King Mattress
We received this mattress packed in its box and we took it to the bed and unboxed it accordingly to the instructions. Here is a short video of the process. [...] We then waited only a few hours, made the bed, and slept that night on it. Its been great this first week! Highly recommended and I will write another review after a few more weeks along with an updated video of it. It was awesome to see it take its shape! Thanks

Great mattress. Unbeatable price.
Bought this mattress after trying out several different foam beds at various stores. Macy's had the Serta line of beds and I liked them much more than the others that were there. So I was very pleased to find the mattress on here.

I bought the full sized bed and it came in a box that's roughly 4' by 2' by 2'. The factory folds the mattress several times and then compresses it in a plastic wrapper. I put it on my existing box spring and opened it up and left it sit for about 6 hours for it to reach its full shape.

There was a slight smell to it but nothing unpleasant and by the time I put the mattress pad and sheets on it, I was sleeping on it the first night without any issue.

If this is your first foam bed it will take a few nights to a week to fully acclimate to the difference between this and a spring based bed, so dont give up on it too quickly.

I sleep on my back and side a lot and used to have horrible shoulder and hip pain from a conventional mattress and the pressure points. I am pleased to say this is entirely gone with this mattress.

I normally like a very soft squishy mattress and when you first sit or lay on this bed (especially if it's a bit cold) it's very firm. I laid on it and thought, "this will never work". Then it begins to conform to your body and supports you so well, you'll understand why so many people are switching to this type of bed.

With any foam bed, they hold a little more heat than a normal mattress. I havent had an issue with this one other than during the colder months I had to turn my electric blanket down than where it's normally set and I am fine. I would HIGHLY recommend this bed and at this price you just cant beat it.

Best mattress I have owned
I have had this mattress for over 3 years now and it is just like new. Would highly recommend if you are looking for a quality memory foam mattress at a great price. I have back problems and this has been wonderful.

This is a great mattress!
I was very skeptical when I ordered the product, and when the mattress was delivered in a 3 ft box and I pulled out the mattress folded over and shrink wrapped, I became even more anxious. When you first open the mattress and flatten it out, it will be hard as a rock. This is only because the gel becomes cold and needs time to reach room temperature. I let my mattress straighten out for around 5 hours, and by that time the mattress was completely flat and much softer. I wish the mattress was a little firmer, but all in all I am very happy with my purchase. The mattress is extremely comfortable and I love that the mattress retains my body heat, especially during the winter. If you're looking for a comfortable mattress at an affordable price, I highly recommend this mattress.

So far so good
You have to let this bed have a break in period. It was shipped in a little box and expanded very quickly. My husband built a platform out of wood for the bed. The product only had a smell for the first night or two but nothing like some of the reviews had mentioned. Now it did have a high spot for the first two weeks but after it began to break in things got better. I waited to review this poduct because I heard that these type of beds need to be broken in before you can have a real good nights sleep. We are both sleeping better. I love it even more because my husband wakes up earlier than me and I never ever feel him moving or getting up before me. I love that part. This was a good buy. I didn't give it a five becuse I am a hard grader.

Just Right
I ordered this bed in the offset chance that it would be comparable to the beds in the big chains (i.e. Macy's, Sears, Etc.). I was pleasantly surprised when it arrive on schedule and was set up and ready in minutes. There was no smell that a lot of other customers spoke of. It did have a slight crease for the first few days. However it has fallen and I assumed it was due to packing. I've only spent two nights on it as I'm not moved in yet, but it made for a comfortable sleep. Especially with my girlfriend. Having my arm under her pillow didn't come accompanied with the "dead arm" that happens on most mattresses. All in all it was a good experience and saved a new home owner a lot of money. Thanks!!

Just like the more expensive mattresses
We went to a department store to try out memory foam mattresses and got sticker shoch at the prices. We came home found this Serta on Amazon we ordered it right away. When it arrived we were very surprised to find that it feels like a nuch more expensive mattress. We are very happy with purchase of this mattress. Thanks so very much.

I am in love with my new mattress
I am in love with my new mattress. It's a whole lot firmer than my old one, but a whole lot more comfortable. I had the luxury of testing it at my parent's home first. I have already recommended it several times.

I like it, wife hates it
I purchased this mattress 6 months ago after trying out the Gel mattress in a local store. This mattress doesn't seem as soft as the one in the store. My wife liked it at first, but after a few weeks changed her mind. She now says it is the hardest mattress she has ever slept on, but she seems to sleep well. I have back problems, and I do think the mattress is hard but I also think it helps my back. The gel does help keep you cool, but the foam mattress does hold some heat.

Amazing mattress!
Greatest mattress I've ever slept on. I am about 205 lb and it hasn't had the denting problem other foam mattress suffer from even after a year of use. The gel also helps to keep it nice and cool during the summer months.

Also, there was no noticible smell when I opened it.

Love it!
I had read a lot of reviews before purchasing this mattress and I am so glad I did. It does take two people to set this mattress up, but easy to place, remove the package, and let it sit to expand. There was a slight odor of chemical, but it wasn't that bad. I opened the sliding door to let natural air in and seemed to be kind of gone by the evening. The bed was comfortable, firm, and felt very relaxed as soon as I laid in it. This was definitely a good purchase for the price!

For a great night's sleep.
This mattress is very comfortable - no pain from pressure points. It is quite firm but we use a fluffy mattress pad which makes it just right for us. The mattress is barely a month old but so far, we love it.

Amazon told me to wait and now i can't return this item.....NICE!!!!!!!
I purchased this bed and the first one came to me falling apart... The replacement one seemed to be ok... we set up the bed and it seemed to take it shape over the next 24 to 48 hours... it had a very high spot in the center on the fold that they put in it to box this item.... the high spot never went away... i spoke with a amazon rep. and the said that it should relax and lay flat... it has been almost a year am I'm still waiting for it to lay flat...i have to lay in the middle of the bed to cuddle with the wife!!! this don't make me happy... so it looks like I have to spend more money and get a new one...i just spoke with a Amazon rep. and he told me that the return window was only a few weeks from purchase... so i waited as asked and now i can't return this item...I to me seems like i was told to wait so that they didn't have to return this item!!!!! Amazon is usually good with things like this but per there request that i wait i loose out??? this just don't seem right in my eyes... i guess I'm out the 581.94 that i paid... YOU HAVE BEEN WARNED DON'T BUY!!!!!!

Gimmick product, period
I bought this in hopes of finally getting good night's sleep on a comfortable mattress. That didn't/hasn't happened. Hands down the dumbest purchased I've made off Amazon ever. This thing is HORRIBLE.
Main complaints:
*Stiff as a board.. No matter the temperature (they claim your body temperature will fix it as it heats up)
*Stinks of chemicals. Not sure what its made out of but WOW! Smells like I'm sleeping in an open can of paint.
*I weigh around 190lbs and I don't even make a dent in this thing. I don't sink in and it sure doesn't "form" around me.

Talking to a retail seller of these he told me more foam mattresses are returned than kept. The floor models are beat down versions of the real things so people can't feel the stiffness.

Gimmick product, period

Good company bad product.
This company is good but the mattress sucks. The first one we got we thought there was a defect because where we sleep there are large indentions but since they replace the mattress the same thing is happening .

If you buy this, don't plan on staying out of it for long.
If you buy this, don't plan on staying out of it for long. This mattress is so deliciously cozy that after the first night, I ordered one for my daughter as a birthday gift. No more legs cramps, neck pain from sleeping in the wrong position and the mattress doesn't heat up like the regular memory foam beds. SOOOO nice!

SERTA DOES NOT MAKE THIS MATTRESS. WARRANTY IS THROUGH OTHER MANUFACTURER. READ ISSUES BELOW
We purchased on 10/30/2011 and keep a protective mattress pad/cover and deep pocket fitted sheet on at all times. We paid $583 for a queen back them. We have just reported issues to Serta, who told us Sleep Innovations makes the mattress for them. Sleep Innovations are now Innocor Comfort out of New Jersey. We have to deal with them and not Serta. Wish I would of known that back then. The issues we are having is that the Gel Foam has shrunk 1.5 inches on the foot of the mattress and 1 inch on the one side, across the entire width and length of the mattress. In addition, the seams are coming apart and separating on the top of the mattress cover. Innocor emailed me a form to fill out and I have to send them a copy of the Amazon receipt and photos of the issues. We will see how the warranty comes into play and if they make good on a replacement or refund. Will keep everyone updated.

Not Bad for a Serta-ish Mattress
We had a spring mattress that was causing back problems, went to 100 stores and looked at the memory foam options, then decided to buy this one because it was less than half the price. The one caveat is - the mattress says it's Serta but it's not really. It's made by Sleep Innovations (who is not Serta). We talked to support about it when all the docs showed up in a Serta envelope but were labeled as Sleep Innovations and they seemed confused about it as well. Then we called Serta to ask about it and they said they sold the rights to Sleep Innovations to make the mattress and use their logo to help sell it. All very confusing and more complex than it needs to be - but at the end of the day, we like the mattress so far and it wasn't outrageously expensive. Now onto the actual mattress...

It's definitely pretty firm. I think we've had it long enough now that it's officially "broken in". We did add a topper to it to make it more comfortable. If you have a low bed platform, you'll probably want to buy a solid riser (unless you like doing an ab workout to get in an out of bed). So far, I'd say worth the money. Will come back and re-update in a few months.

4 years later and it's still wonderful
I waited to write a review ... and then I forgot about it. I bought the mattress in 2012 and today in 2016 it doesn't have dips or depressions where we sleep and is wonderfully comfortable. There are two things to consider about foam mattresses and it's a little confusing. 1) FIRMNESS - This is is ability of the mattress to support you body without sagging or forming depressions. This has to do with the density of the foam. That's why some reviewers talk about how heavy this mattress is - it's because it's so firm - and that's a good thing. It's why 4 years later the foam is still in good shape. 2) SOFTNESS - This is the Pillow Effect on the top of mattress that gives you comfort. This mattress is very Firm but not Soft on top. And that makes it feel a little "rock like" to some. If you like a lightly pillowed top I HIGHLY recommend a 2.5 inch gel mattress topper. (The one Costco sells is perfect). I know it seems like the whole mattress is now more expensive but too many other less expensive mattresses sag (are not firm enough) to hold up over the years, and that's false economy. Also trying to dispose of a heavy foam mattress is not fun. My husband and I think this mattress is wonderful.

Firm. Supportive. Not Plush.
We have been sleeping on foam mattresses for a long time and will never go back to springs. This mattress in particular has excellent support characteristics but if you are looking for a "plush" feel, you will need a topper. This is a firm mattress which supports the body. It is not a mattress you sink into like a cloud. Some will equate that firmness with being an uncomfortable mattress but really it is just for people who prefer firmness to plushness. Before you buy this one online, you should go to your local mattress store and ask to try their most firm mattress. You must lay on a foam mattress for more than a few seconds to give it time to adjust to your body. If the firm feels right, this will suit your needs. If you need plushness, keep shopping.

On a side note, another advantage to a foam mattress of this thickness is that you do not need a box spring. Whatever you put this on will be fine for a bed which means you can make a pretty cool artistic platform beds, or set it on a board or cinder blocks or whatever and as long as there is a flat surface directly under the mattress, the feel will be the same as if you used expensive box springs.

not for us
This gel foam mattress was really hard for me. I was 9 months pregnant when we got this mattress and I thought it would be good because it can help me get a good nigh rest by having a good support. Nope. I was wrong. It felt like I was sleeping on the floor. Every time I move it hurts. Plus it wasn't comfortable because it was hot. Don't know why since it's suppose to have a gel foam but I guess that doesn't work for me. If you prefer plush mattresses, this is not for you.

Comfortable
I've purchase memory foam toppers in the past and wound up very unhappy with them. I would sink in too much and wake up throughout the night just to turn over. I've had no problems with this and now realize there is a HUGE difference between toppers and a real memory foam mattress.

First off, this thing weighs a lot, nearly 100 lbs. If you don't have a strong man to help you with this, you will have trouble. UPS had to help me in the door with it on a dolly. It arrives in a box, contorted and airtight sealed. Unpacking was a two man job and we unpacked it right on the frame.

This mattress does not sink much when you lay on it and reminds me very much of quality mattresses of years past (prior to pillowtop.) No achy back from this mattress! The hardest thing we had was finding a proper platform for it. Wound up going with the Structures by Malouf HIGHRISE Folding Metal Bed Frame 14" High Bi-Fold Platform Bed Base, KING and didn't even need plywood or anything. We put the mattress straight onto it and this was an affordable option over a platform.

I will need a new twin mattress soon and I will definitely be getting one of these mattresses for that bed.

****UPDATE: Aug 14, 2012****
I now own two of these. After having owned the first one for quite a while, I felt the need to come back and clarify something.
Foam mattresses and toppers are hot to sleep on. I thought everyone knew this, but since they don't, I needed to let them know. If you are prone to being cold, you will like this mattress. If you are prone to being hot, you will hate this mattress and definitely wake up sweating.

GREAT MATTRESS
COULDN'T BE HAPPIER. I AM A SENIOR WITH SEVERAL ORTHOPEDIC ISSUES. BECAUSE OF PAIN IN MY HIP I WAS HAVING TO SLEEP ON THE COUCH, WHERE THE DEPRESSIONS BETWEEN SEAT CUSHIONS FIT MY CURVES. NOW I CAN SLEEP IN BED AND MY HIP DOES NOT HURT. I HAVN'T BEEN ABLE TO SAY THAT FOR 2 YEARS. SHOULDER PAIN ON THE SAME SIDE DID NOT RESPOND AS WELL BUT IT IS ALSO IMPROVED. SINCE I AM MENOPAUSAL, HEAT WAVES -NOT FLASHES- KEPT ME FROM TRYING THE ORIGINAL TEMPERPEDIC TYPE MATTRESSES, BUT THIS SERTA GEL FOAM MATTRESS DOES NOT TRAP THE HEAT, JUST LIKE THEY SAID. SINCE THERE WAS SOME DISCUSSION ABOUT SMELL, (AND A SERTA PILLOW I PURCHASED DID HAVE A STRONG ODOR FOR A FEW DAYS) I CHOSE TO OPEN THE MATTRESS IN ANOTHER ROOM. THIS WAS NOT NECESSARY, ODOR WAS VERY LOW. I HAD LAID IT ON A SHEET AND WE WERE ABLE TO MOVE IT EASILY TO THE OTHER ROOM. GREAT PRODUCT!!
