This was the best money i ever spent on bedding. It made a very hard mattress quite comfortable saving me money as I did not have to buy a new mattress. The cost was also very reasonable compared to others. I was initially leary as some other reviewers said this was not memory foam, but it most definately is. It does bounce back. I had no smell issues either. I aired it out as directed on the package. I had none of the problems some of the other reviews mentioned. I would recommend this for anyone that wants to make a hard bed cushier.
