  • Comfortable, little on the firm side

    I was trying to decide between this mattress and some of the other mattresses sold on Overstock. Saw a number of negative reviews on some of them, and was hesitant to order this mattress because there were no reviews posted. After finding some reviews on other sites (which had the mattress for ** higher if not more, I proceeded with the order from Overstock. The mattress comes very well packaged, the cardboard box has a cardboard sleeve on the inside which holds the outer plastic sleeve with the bag containing the mattress. The mattress itself is in a vacuum bag and is fairly heavy. As with all other memory foam mattresses, on this one the same advise goes: Place the vacuum packed mattress on the bed / box spring prior to opening, it's a lot easier to get it in place (especially if you're setting it up by yourself). The mattress took only ~1 hour to expand to it's size, and I didn't notice any odors coming from the mattress. I am using a platform bed with slats as base for the mattress. Overall it is very comfortable, but more firm than I expected (I only had foam toppers on a standard mattress before). However it contours nicely after laying on it, and I sleep better than I did on my traditional mattress with topper.

  • Wonderful mattress!

    Comfortable sleeping mattress that has miraculously eliminated most of those morning aches and pains. Not to hot or too cold to sleep on, molds to my contours, and remolds when I change positions. Either satin or microfiber sheets work well with it. Have not tried cotton or blends.

  • Best mattress. Wish we had purchased it sooner.

    This matress is the best ever. I wish we had purchased it before our last one. It is the best nights sleep we have ever had. When you receive the matress make sure you don"t open the plastic until you place it on the bed frame it is going on. After it is open it is a little hard doing it alone. Great value!!

  • Serta 12" Memory Foam Mattress

    Still too new to review but it sleeps well. Says Serta, but it is actually made by another company for Serta. It is American made and seems to be the best bang for the buck.

  • Much too firm

    The mattress was a great deal, but it is way too firm. We bought a topper to go on it after months of restless nights. With the topper, it works out really well.

  • Good Value

    OK, if you think your getting a temperpedic for a quarter of the price, you're not. It's a pretty good imitation however. It settled into shape in about 24 hours and there was very little odor which dissipated quickly. It's a bit softer and bouncier than our temperpedic, but for four or five nights a month at our weekend house, it been an acceptable alternative. I am guessing that if you have never had a temperpedic you would be pleased with this mattress which is big upgrade in my view my an inner spring style mattress.
