Linenspa

Founded in 2003, Linenspa is a very low-priced mattress brand that sells affordable memory foam, latex, and hybrid mattresses. With their incredibly low prices, Linenspa mattresses feature budget materials. Due to these low priced materials, customers report complaints with durability, mattress construction, heat retention, firmness, and support.

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.

Linenspa's Owner Satisfaction

Sleeper reviews can be hard to understand from a high level -- especially with all of the marketing being done by companies and retailers. These mattresses, unfortunately, don't score as well with customers. There are still customers that are very satisfied, but many others who are not. Learn more below to understand the specifics.


Linenspa's Supportiveness

In terms of having support long term, these mattresses get mixed reviews. Some customers feel comfortable and well supported, but others didn't feel that the mattress was equipped to provide comfort. If you are above average in weight, you may want to do some added digging into reviews to make sure you find the right pick for you.

Edge Support
Edge support is an important item for anyone that likes to lounge on the side of their mattress or has mobility concerns. Some customers have found these mattresses to not be evenly supportive.


Linenspa's Durability

Mattresses that are very durable are great, but difficult to find. Unfortunately, these mattresses are not well rated when it comes to durability. That said, some mattresses may last a significant time without problems, while other customers may have much faster discomfort. If you are a heavier individual, read up on your options because you may be at a higher risk for durability issues from some mattresses.

Serta's Owner Satisfaction

Understanding customer feedback can be a great relief when spending hours searching for the right product. Customers, unfortunately, don't always enjoy these mattresses. Some are content with the feel and comfort level, but others are not so much. If you are considering purchasing, make sure to get more information below.


Serta's Supportiveness

Firmness isn't the same as support. Great support is when your mattress aligns the spine and leads to a better night sleep. Unfortunately, these mattresses aren't the best in terms of support. Most customers are comfortable with the support right after purchase, but some have reported support issues as time as gone on.

Edge Support
For those that like sitting on the side of their beds, edge support is key. At first, these mattresses do a good job with edge support, but some may find that it changes over time.


Serta's Durability

Unfortunately, customers don't always love the durability of these mattresses. While some folks describes them as comfortable for them, others describe feeling issues and discomfort of a short time. If you are thinking about buying, read up on the return and warranty policies beforehand.

Mattress Get Uncomfortably Hot
The mattress feels good for support (that's the reason for a 2), but it retains body heat to such an extent that it is extremely uncomfortable and I am unable to sleep on it for more than 2 hours. As the body cools down a lot of heat is given off and it becomes trapped in the foam. There is no place for the heat to dissipate through the 10 inches of insulating foam. Even with multiple layers of blankets between the top of the mattress and the bottom sheet, it's like trying to sleep on a warming tray. It's necessary to get out of bed for a while to cool down before trying to sleep again. Body exposed to room air is cold while body against the sheet roasts. We could not find an acceptable solution to get rid of the trapped air.

It's a nice mattress. I ordered a queen & I measured
It's a nice mattress. I ordered a queen & I measured it and it came out 3 inches short on length and width. If this isn't a problem to you then it's a great buy.

When I first got this mattress I was in love, it is so comfortable it is still comfortable
When I first got this mattress I was in love, it is so comfortable it is still comfortable, but after 8 months I have this curved lump on one side of the mattress, I have enclosed screen shots. I was hoping after only 8 months it would have lasted longer. You can feel the lump : (

It was great for the first few months but now you can
Bought this mattress for my daughter. It was great for the first few months but now you can really feel the sprigs when you lay on it. I’m looking to purchase something else now. I’ll probabl give this mattress to a homeless man in our local area.

I was very surprised
I was very surprised about how compact it was upon arrival. The price you paid is worth more than for the product. The mattress is really soft and comfortable. It doesn't bounce like any other spring beds.King bed is scuh a big it can easily accommodate parents with child.

Comfortable
Comfortable, plush, surprised the cost was so reasonable. I'd buy it all over again!

We bought the twin size
We bought the twin size for my daughters daybed. It is sooo comfortable, and light weight. Not only does she sleep through the night,changing the sheets are abreeze!!

This is probably this best mattress
This is probably this best mattress I've ever had. And for this price? Really can't beat it in my opinion.

Waste of money for lies about memory foam
No where near 8 inches, they lie! Has 4 inches of sptings and one inch of crappy ''memory foam''. It hurt my back and legs, and made me sweat all night. Horrible mattress and a waste of money!

This is ok for the price
This is ok for the price. It is a little firm. If you have a big toosh, it is not the most comfortable to lay on your back since it is so firm. I think I will need to get a mattress top to add extra support to my lower back. It isn't too bad on my sides, but then the same problem with my hips being big. If you need something a little softer, I would send the extra 50-80 dollars on something that might be thicker.

Great value
Great value for the money ! I weigh about 130lbs and it feels nice & comfortable. I have been sleeping on it for 2 weeks now and it's just the right balance between soft & firm. Also, it is convenient to carry as it comes rolled up in a box. When cutting the plastic outer wrap it was fun to watch the springs expand as the mattress actually rolled itself out ! Thank You Linenspa.

Bought this mattress
Bought this mattress (full size) for my 8 yr old daughter for her new bed. Absolutely love it, so comfy. Would definitely buy a king sized one when I'm looking at getting a new mattress for my husband and myself!

love this mattress
I love this mattress! It's the perfect combination of firm with a comfortable top. I have gotten one for my 6' 16 year old son. I ordered a pretty simple frame and twin mattress for less than $200! I am now looking into a full size for m 21 year old son.

Way
Way too flimsy

I bought this
I bought this for on a twin bed for my 5 year old niece. Very soft and comfortable. My niece loves it. Great value for the price and even better, I bought it on sale.

This mattress is amazing!
This mattress is amazing!! I wanted the most comfort at an economic al price. I did hours and days of research and chose this one in a King. It literally feels like I'm sleeping on a cloud! I have never had a better nights sleep. This is the best mattress I have ever owned.

This is the most uncomfortable
This is the most uncomfortable bed ive ever slept on! I wake up with a back ache every morning and my shoulders and hips just dig into the bed. My husband moves around the whole bed every night trying to find a comfortable place. My 8 year old bed is more comfortable than this bed! Now i have to go buy a mattress topper so i can sleep and not toss and turn all night!

I can't say enough good things
I can't say enough good things about this mattress. I bought both my kids one and they have never slept better. I have slept on them and they are incredibly comfortable. I absolutely love it!!

I purchased this mattress
I purchased this mattress for my almost 3 year old's bed. This mattress is a very good quality. It seems very durable and comfortable. My son loves his new big boy bed. I bought the twin sized one. I was afraid that twin sized sheets wouldn't fit on it since it is hybrid, but they did. I kept my receipt for the sheets just in case, but thankfully they fit perfectly. The only additional thing that I would recommend is not cutting the 3 tape wraps until you have the mattress on the bed. I intended to put the mattress on the bed before I cut the final two tape wraps. However, once I cut the first tape wrap off, the other 2 tape wraps broke. The mattress basically had an exploding open effect.

Just what I needed
Just what I needed! Perfect! Light weight too making them easy to move around. No boxspring needed is an added plus!

It took several attempts
It took several attempts to buy this mattress from the website. Everytime I bought it, the next morning I would see that the order was cancelled. Finally it got ordered, then when we went to the store to pickup, they had a hard time to find it. It's now home, in place and my daughter loves it.

I recently bought a canopy
I recently bought a canopy twin size bed for my daughter and needed to buy a mattress for it. I was kind of hesitant about purchasing this bed because it was $77. I read the reviews and decided to give it a try. This mattress exceeded my expectations. It was shipped to store. It came rolled up in a box and it was quite heavy but that is to be expected. Opened the pacakge and let the mattress rest on the floor to let it expand all the way. I laid on the bed for 3 minutes and liked it so much I decided to purchase a king size for my husband and I. My daughter loves her mattress. It is beyond comfortable. Don't be turned off by the price. Even though it's cheaper the mattress is of high quality.

Price and quality
Price and quality: It deserves a 5-star except that I think the dimension for the width of the twin bed is OFF ... it is 37 or 38 inches NOT 39 inches as it says on the web as far as I can see. I was worried it would NOT fit my 38 inch bed but it fit perfectly. Please fix your specifications.

I love this mattress
I love this mattress. It has the perfect amount of firm and plushness to be like sleeping on a cloud. After having many a mattress over the years I have to say this is by far the best. My only gripe with this product is that if you are a heavier person, like me, then it seems the springs won't last too long, considering when they get compressed too much they make a popping sound. I wish they made a 10 or 12 inch mattress just like this, that would be great!

Wow
Wow! What an awesome mattress for the price! This arrived quickly and we immediately took it out of the box. It easily unfolded and within minutes it was at its normal size. So soft! And it's firm but not too firm. Perfect for my 5 year old!

It is a very firm mattress
It is a very firm mattress, considering it came rolled up in a box. It is also a very lightweight mattress, I had not trouble getting out of the box by myself. I am 60 years old with arthritis and did not need any help.

Come compacted
Come compacted just watch out opening it will spring out quick lol it's firm like my mattress soft so I ordered a foam mattress go on top 3inch gel worked out great comfy sleep.

Great buy
Great buy. The price is great but the mattress s is Awesome. I bought two mattresses. 1 named brand and more expensive and liked this one better. Wish I would have bought 2 of these.

Very comfortable
Very comfortable, softer than a hard bed, love the memory foam. Price is certainly reasonable. Quick delivery, even over the holidays. Will definitely consider again.

This mattress is very comfortable
This mattress is very comfortable. Best purchase I've made in quite some time.

This mattress is awesome
This mattress is awesome. It's medium firm, it's perfect for a good nights sleep! It's also a lot of fun to open the box it comes in... Yes, a box! You'll see why when you purchase one... Hehe

This bed was so much better
This bed was so much better than I thought it would be. It is for my 18 year old son and he loves it. It didn't take long to get up to the 8 inch size and is very soft. He loves it!

I ordered
I ordered this mattress for my daughter. I was a bit skeptical I'm the quality it would be because it was so cheap. But for the price I decided to try it. The mattress came rolled up in a box such I had never seen. I opened the box and plastic and instantly it started to expand. My daughter slept on it that night and loved it. The mattress is on the firmer side but very comfortable.

It's really cool
It's really cool that you can order a mattress and have it shipped in a semi small box to your home! This is very nice and comedy for being a hybrid. It has about an inch to two inches of memory foam on top of the springs so it's very comfortable. The fabric is nice and soft too. This would be perfect for a guest bedroom and or for a kid maybe not for every day sleeping for an adult but definitely for a teen. My son loves this mattress and the price was right!

I love this bed
I love this bed. My family thought I was crazy buying a mattress from the internet without ever laying on it but I had a good feeling about this mattress so I did it. I just bought it sight unseen. I am SOOO happy that I purchased this bed. It is so comfortable. The outer layer is nice and soft to the touch, it is true to size so the sheets fit, which is great, it is soft yet supportive which is why I went with the memory foam/innerspring hybrid mattress. I was a little concerned when I saw the bed arrive in a tall skinny box but we brought it in and opened it up and as we were cutting the outer plastic layer that sucker just popped right open. Freaked my husband right out. It didn't take long and it unfolded and came right back up to size. It was really neat to watch and even better to sleep on. Even my husband agrees and that is hard to get him to do. If you are on the fence about buying this mattress I highly recommend it, you won't be disappointed.

This is AWESOME!
This is AWESOME! So nice not to have to deal with delivery trucks and delivery guys. This came in the mail, easy peasy. Opened it up, and the kids LOVED how it was vacuum sealed and popped right up. They immediately jumped on it. LOL Got this for my son's 4th bday- he is so excited. I wish I could show you the video of how excited he is! I love the foam topper on it. Even with joint pain, I feel very comfortable on this mattress.

This is a very nice mattress
This is a very nice mattress. I was very surprised about how compact it was upon arrival. Once you carefully open, it takes a few hours to fully expand (even though it really pops right out of the package). The mattress is really soft and comfortable. It contours to your body and isn't incredibly bouncy when you move about. For a thinner mattress, it actually is very comfortable and provides excellent support.

I purchased 2 semifirm
I purchased 2 semifirm mattresses and both are quite good... however, semi firm is not as firm as it should be...next time ill go with firm..but overall very comfortable..

I needed a new mattress
I needed a new mattress and I did a lot of research before picking this one. There are a lot of popular online mattress stores (casper, lisa, purple, tuft and needle) but all of them were way out of my budget, especially since I wanted a queen. I saw this one had great reviews and I price I could afford so I chanced it. It shipped quickly and arrived rolled up in a long box. After I cut the plastic, the mattress began to hiss and expand with air. It was really cool. Within a few hours it was ready. I've been sleeping on it for 3 months now and have no complaints. It's the perfect mix between soft and firm.

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!!
