I was a little worried when it arrived rolled up in a box that there had to have been a mistake. But I was very surprised how fast it got it's shape. The machine washable cover is great. There was a slight odor for a couple days but it did'nt really bother me as I expected worse. Almost a year later now and it's still like new. Most comfortable bed i've ever slept on at a fraction of the price of the big name memory foam.
