    • It really does what the video states!

      Watch the video by Christopher Knight. Mattress comes wrapped very very tightly (like a rug). After you cut off the plastic, (be careful doing this) the mattress starts growing and growing. I got the medium firm style in full and it is pretty firm. Glad I did not get firm. I am extremely pleased with this mattress. It is being used without a box spring on a platform bed and it it sturdy and perfect. I purchased the 11 inch.

    • Had this mattress for 6 months its not any better.

      I bought this mattress for my daughter, she complained that it was hard. I told her to give it time it will get better. It never did and now it has a lump in the middle. My daughter is 5' 4in and weights 104lb. There should not be a lump. I also purchased the SwissLux 8-inch Twin-size European-style Memory Foam Mattress for my sons trundle bed. It is awesome. He loves it. It is soft yet not to soft. I tried my daughters and she is right it is too firm for memory foam. You don't get a good nights rest, I tossed and turned all night. I will have to wait a little will but I will get her the SwissLux European-style Memory Foam Mattress in full.

    • Great Comfort

      Arrived quickly. Unpacked easily- no smells- and it expanded within minutes; but I left for additional 12 hours before sleeping on it- Very Comfortable- It took me a long time to decide on make of a memory foam mattress- wish I had ordered this mattress sooner!

    • Best mattress purchase ever

      I love this mattress and it was so easy to order it from Overstock. The mattress didn't smell funny like some reviews suggest. Highly recommend this to everyone! I had back surgery and it is tough for me to get comfortable and not be in pain but I am never in pain on this mattress. It is perfect and is the reason I love it so much. Also, when ever I have my girl friend over to stay the night she sleeps so well. So do I - every night. The gel keeps me cool (I am a hot sleeper). When my friends are in my room (I have 4 roommates) they are very quick to relax or lounge on it while I sit in my computer chair doing work (I produce music and have a tech start up so I am often asking their opinion on projects, etc.) They always tell me how great it is. Three of my roommates purchased one very similar to this. They chose to go a little softer but bought from the same brand. I think they all secretly wish they had mine although they say they love theirs as well. I definitely like mine better.

    • Correct firmess, no smell and perfectly cool

      I did a bit of research before purchasing this mattress. I'd gotten one from overstock several years ago and that was my first memory foam mattress. It was fine but usually slept too hot and would soften up more than I liked after I'd been in bed for a while. I bought this mattress because of the medium firmness and based on the reviews on here it seemed like it struck a happy medium between support and being too hard. I also bought this because of the aloe gel, which is supposed to be more comfortable and cooler. Overall I'd have to say that this bed hits my sweet spot. It doesn't retain too much heat, the aloe gel is a nice comfortable layer on top of a properly dense underlying foam. I weigh about 210lbs on a 6'1" frame, so I put a decent amount of load where I'm sleeping. I'm also a side sleeper, not sure if that helps anyone else reading this review. I've found the bed quite comfortable for sleeping, with sounder nights of rest. It's also quite nice for laying in and reading, watching a movie etc. An added bonus is that this mattress doesn't seem as heavy as the last memory foam I had, so moving it around to change the sheets is not too much of a strain. Shipping was fast, mattress arrived in a large, somewhat battered box. Inside was the mattress, double wrapped in plastic. It was very easy to remove the plastic and the mattress regained it's full size almost immediately. Keep in mind this is during the summer, so maybe the foam being warm helped it to expand quickly. I noticed almost no smell and by the time I slept on it later that evening, it was totally gone. Hope this helps!

    • Good Mattress for the Price

      You just about can't go wrong. For the price this is a great mattress. Slightly on the firm side, but not so much that it has caused any problems. Shipping was very quick and it enlarged to full size in a an hour or so. It had no odd smells or anything of the like. Doesn't retain heat as we told by some.

    • Best night sleep ever!

      After waking up with a stiff neck, back pain, and a sore body for months my boyfriend and I decided it was time to purchase a new bed. We've been talking about memory foam mattress for quite some time and I finally found a website with affordable prices. He was a bit skeptical about buying a mattress online because he's the type to try the product before actually spending the money on it. It took weeks of persuading him that this site was actually legit. Shipping was fast and customer service was great. When the bed finally arrived it was little to no small at all and it took only a couple hours before it actually inflated to the full 11 inches. I must say, this is the bed thing we've ever spent money on. The first night we only slept for 4 hours but we woke up refreshed with absolutely no pains whatsoever. We also bought two biopedic pillows and a new comforter set. THANK-YOU, OVERSTOCK FOR THE BEST SLEEP WE'VE HAD IN A LONG TIME!!!!!!!!

    • positive review title

      A good buy for the money. Yes it smelled funny for a week or so, similar to the eggcrate mattresses we used to use in the hospital. I put a quilt on mattress and then regular bedding to hide the smell. Smell is gone now. My first memory foam mattress, I got this gel top. It is more firm than I would have thought or wanted but for back support it works very well. Comes out of shipping box about 4 inches thick. Inflates itself over a few hours to the advertised 11 inches thickness. I am happy with it and would purchase another when the time comes. Much cheaper than buying a similar set up from any bed shop.
