      I ordered this mattress but some other type of mattress was delivered, and Overstock would not deliver the mattress that I had bought and paid for. I will not use Overstock again.

      Purchased this mattress for our spare bedroom. Loved it so much that we bought the 14-inch queen for our own bedroom. Best purchases we could have made!

      Opened vacuum sealed plastic to let mattress go back to its original shape. According to directions, it would be back to normal by 72 hours. It has been a month and it has still not flattened out like it is supposed to.

      I bought this for my daughters room. I read the directions before I did anything and it said it could take up to 72 hours before it completely unfolds to its original shape. I am now on day 5 and the mattress is half unfolded and doesn't seem to be changing at all. I now have to go through the hassle and send this junk back. I wish I would of listen to my gut and not order this. Really shocked at all the positive reviews this thing got. Learned my lesson, will never order a mattress online again....
