The product was just what I needed to better support my back. The quality is great and it functions like a temperpedic bed but without the cost. It came with a cover that easily fit over my present mattress. The foam retains its original shape after getting up and so far has definitely helped to relieve a great deal of aching that I have suffered for a number of years now. I have tried mattress after mattress and this seems to do a better job than any of them.
