    • Comfortable, little on the firm side
      Verified Purchase

      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!
      Verified Purchase

      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.
      Verified Purchase

      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!!

    • Comfortable mattress
      Verified Purchase

      It's amazing. This mattress came in a box that was about 48" high, 24" wide and 24" deep. You open the box and the mattress is wrapped in a Saran like wrap. Just cut the wrap and the mattress opens and you never would know that it was all folded up. The mattress is very comfortable. I'm short and it was placed on a pedestal in a park model trailer so I need a small step to get up on it. With the mattress being 12" high I have a little trouble getting the sheets on. I personally would go with a bit thinner mattress, but my husband wanted this one. I would and have recommended this mattress to others.

      Got this for my son, who on the fly needed a new bed. I came in a box! We didn't even know it was the bed but he said it's the most comfortable thing he's slept on.
