I chose this particular memory foam mattress because it claims to have a feature of "cool" that would address the negative feature of memory foam generally, that it produces heat. Of course the price was right, too. The mattress arrived and was unpacked promptly....it was packaged quite judiciously and unpacked easily. There were no odors, as some memory foam mattress reviews indicate. I waited and waited and waited for it to loft to 8", as described., but it never mustered more than 7" . . . .It is rather soft, probably more so than the name-brand one...but it is still comfortable though I am not sure if this feeling will last.....I need another mattress for the bottom of the day bed, but I don't think I will buy this one again---especially now that the price seems to have shot up!
