    Like the other reviews, I am so pleased with this mattress. First, I switched from a 15-year-old traditional pillow-top mattress and box springs to this memory foam mattress. I had purchased a 10" memory foam for my daughter last year and knew I had to have one for myself too. I am like Sherlock Holmes when it comes to researching products before I buy them, so let me say I have done all the research you could possibly fathom doing, and I picked this mattress. Second, the smell was a non-issue - what smell was present was gone in two days (seriously, let it sit out for two days like they recommend even if you think it is "ready"). Third, my husband and I both are very pleased with this mattress - we are both 35, average height and weight, and we feel it is supportive for us without being too firm or too soft. I will say that the Aloe/Cooling feature is definitely noticeable and not a sham: We have a goose down comforter and were sweating with the combination of the comforter and our previuous mattress, but first night in this new mattress and we noticed we were comfortable all night long without being hot or cold! We have had this for three weeks now and the only problem I am having is that I never want to get up! I used to be the snap-out-of-bed as soon as the alarm went off girl, but now sometimes I donít even hear the alarm going off, because I am sleeping that well. I actually wake up in the same position I fall asleep in, and that is impressive. I used to wake up multiple times at night, and I do not do that anymore. Additionally, my small dogs sleep in the bed with me and they actually STOPPED SNORING with this mattress!!! That was a sweet bonus. I notice my husband snores much less now too. You won't be disappointed with this one - the price is almost criminal for what you are getting. You cannot put a price on a good night's sleep. Another bonus - it has strong handles sewn into the cover, which is awesome because you are going to move it eventually. Read this (http://www.memoryfoammattress.org/) - it will tell you everything you want to know about memory foam, then go compare to the one that costs thousands of dollars and you'll see why I picked this mattress.

  • Great Mattress

    This mattress arrived very quickly and expanded within 24 hours. The mattress is great for side sleeping or on your back. It really forms to your body and it keeps you cool. I was worried about buying a bed before trying it but I really don't regret it now. We have been using it for a month and we have had much better sleep then on our old spring mattress. The mattress stays cool which is a plus as well. My partner likes soft mattresses and I like firm, this one is right between and it feels great. Warning, if you buy this mattress you better buy a really good alarm clock. It is hard to get out of bed in the morning.

  • Cool and comfortable, great support!

    I'm thrilled to get a gel memory foam mattress for about a third of what they cost retail!! They're so expensive I wouldn't have done it without Overstock. All the reviews on the site were helpful too, in deciding what I wanted. This is the first time I've ever bought a mattress I couldn't try out first, so that seemed risky, but all the good memory foam mattress reviews made me think it was worth it. It arrived securely packaged and it was easy to set up. Have been really happy with it so far, and don't have back pain in the morning anymore like I did with the pillow top mattress I replaced. This mattress is listed as medium support, but I'd call it medium-to-firm and that's what I like. The cooling layer keeps it a comfortable temperature, it doesn't become too warm the way I've heard other memory foam beds do, so that feature is worth selecting this particular model. Now if only I had more time available to sleep. . .

  • Amazing comfort!

    This is a great mattress, I suffered from back pain for a long time - sleeping on a high quality - high priced spring mattress... NO MORE! This mattress arrived quickly and unfolded with a hiss of air to fully inflate within 3 hours. That night we (the wife & I) went to sleep on it and where stunt at the comfort it offered! I now sleep through the night without waking even once - I can flip & turn without my wife knowing or filling it... I love sleeping on this mattress and I highly recommend it, for this price - you can't beet this deal.

  • Holy crap.

    As of writing this review I've had the bed for ~4 months. To start with, I'm a broke, full-time college student. I had been sleeping on the couch for several months waiting for my financial aid to come so I could buy a bed. I spent that time researching very carefully: differences between spring mattresses and memory foam, reading dozens of reviews on both, watching the prices, and going in to local stores to test/daydream my future purchase. When it came down to it, I was swayed by finding virtually *no* bad reviews about memory foam mattresses. The simplicity of picking a memory foam mattress over a spring mattress also did a lot for my peace of mind: I don't have to worry about whether I got the right layers "tailored to my sleeping style" or whatever crap the local mattress stores tried selling me to justify their prices. There were two concerns about memory foam mattresses that I saw consistently in reviews: smell and heat retention. I specifically sprang for a mattress with the aloe layer because I like to be cool when I sleep - layer-on-the-comforters-and-still-have-numb-toes kind of cool - and I have no complaints about being too hot. Also, there was no off-putting smell when I opened the mattress. It had a new-thing-that's-in-lots-of-packaging kind of smell that wasn't unpleasant and was gone by the time I had let the mattress do its expanding so I could sleep on it. Any mattress is going to be bulky and have weight. I unpacked it and set it up with the help of my boyfriend, I could have managed it on my own, but it would have been difficult. That being said, moving the bed around by myself is much easier now than with any spring mattress set I've had, as it's just the mattress on a platform bed I bought to go with it. No bulk, very simple, and very nice visually. I've moved to a new apartment since getting this mattress and it was simple to move, especially since there were no box springs to haul around. It has fabric handles on the sides that match the rest of the material of the bed that are strong enough to move the mattress around with. I don't feel like I really need to go into detail about the comfort - if you've done any research on memory foam mattresses, you're going to see the same thing over and over again. Yes, it feels like heaven. I have had problems with insomnia since childhood and even when I'm not actively struggling with them, it normally takes me a very long time (an hour or more) to fall asleep. I fall asleep very quickly on this mattress, I sleep very soundly, and when I wake up I feel ready to get out of bed instead of wanting to lay around in a half-sleep coma for another couple of hours. Oh, and as a bonus, that commercial on T.V. that shows the woman jumping on the bed right next to her partner is TOTALLY TRUE. If you're sharing the bed with someone, it's SO much easier to get in and out without waking them up. Also, a small side note about the customer service: the very next day after I ordered this mattress the price dropped $50. When I contacted customer service about it, I got disconnected part-way through the conversation. I received an e-mail from the agent I was speaking to within an hour with the information I needed. They were able to escalate the issue to the warranty department for me so I could use the price difference to get the 10 year warranty, which I had forgotten to pick up when I made the order in the first place. Tl;dr: Get this bed. It feels wonderful, it's a great investment for the quality of your sleep, and is a much better value than anything you'll find in a brick-and-mortar store. Spring for the 10 year warranty: it comes with a mattress protector, covers bodily fluids, and, barring acts of God, you will have this bed for that long.

  • I sleep better

    If you've never had a memory foam mattress before, be prepared. This thing has no "bounce" to it so it discouraged tossing and turning. You'll sink into it. I move around much less and seem to be sleeping better because if it. I went to *** and got a piece of plywood to place over the slats of my bed, then put the mattress on top of that. Works fine. I've heard these things are hot in the summer, but I just got mine in January, so I cant tell you if that's true or not.

  • matress hard and chemical smell lingers

    Bought this mattress by reading reviews of folks who wrote how soft and comfortable it was. This is my second memory foam mattress and it is very firm and so not comfortable compared to my last one. I expeced the chemical smell and actually aired the bed for two weeks before sleeping on it. It has been more thn a few weeks now and the mattress still reeks. It plays havoc with my sinuses and makes me have headaches. The mattress is still very firm but I am getting used to it. It is not a soft or a plush mattress. Perhaps it will soften as the weather warms. One good note...the matress is cooler temperature wise when lying and sleeping on it. Much cooler than my last. Fair value for the money. Should have done more research. If you purchase- leave mattress outside, walk on it a lot to help air it out, and if you are sensitive to chemical smells, you may want to rethink.

  • Spinal response

    This Mattress is way to soft. It is like sleeping on a marshmallow. After one night of sleeping I could barely walk. Since you cannot send mattress' back to overstock, you are forced to sell this. If you have a bad back or neck, DO NOT buy this mattress. It is a waste of money.

  • mixed feelings but on the positive side

    Bought item because I started having back pain. I put a 3 inch topper on and it was way too much made my back hurt more. Took that off and decided to go it alone with this mattress. It is firm which I like and a lot better. Felt like a foam pit with the topper on. I feel it is starting to help my back. Takes a few days to get use to. Not sure if it is a lot different from my old mattress which wasn't that old.......so probably if I had known would have just taken the topper off that and got the same result. This mattress had no smell which I have read about in all of the reviews on other mattresses... I thought it would and it did not........I am not using it with a box spring just my bed frame platform.. It arrived VERY quickly. I walked the box into my bed room my self layed it on the bed and undid it there... by myself wasn't a problem.. Seems like a nice mattress......but much like my old one with out the foam topper.....

Hello weasle34! That is such a great question. The aloe infused gel mattress is Certi-pur certified. To become Certi-pur certified, the foams used in the mattresses must have low emission standards relative to "off gassing". This mattress is Certi-pur certified, but does not contain charcoal in the foam. I hope this helps. Thanks for shopping with us. overstockcustomercare1 on May 16, 2013
