LOVE THIS BED! I went from a cheap spring mattress to this very reasonably priced memory foam mattress and I couldn't be happier.  I've had it nearly a year and it's like it's brand new.  I did also purchase a moisture-wicking mattress cover separately to protect it.  The only negative (and to me, it's minor) is that sometimes it's a bit warm, but from what I've read that is very common among memory foam mattresses.  For the price, this can't be beat.
