I decided to try this foam mattress after reading all the good reviews it received. I was looking to replace a Select Comfort twin xl mattress, my side of the bed, as it hadn't been staying set at the number I put it on each night. I do like the mattress, but find it is a bit stiff right now, that may change as time goes on. I like the fact that it is light, but does not feel cheap, and it is comfortable. I can't say I sleep a whole lot different on it, but at this point I don't think that has as much to do with the mattress as it does with me and my age!
