Got mine on Saturday..
I opened the box and the plastic bag to let any chemical smell dissapaite, a major concern of some reviewers. Sunday I put it on the bed, and it took about 4 hours to unroll.
Sunday night - wow - huge difference in sleep, the bed was amazing! I found it noticeably cooler than the mattress, the gel foam lets you sink in like a marshmellow, so moving in your sleep isn't something that happens easy, but you also do not feel the need to move around as much. It will take a few nights to get used to, but it is a definite improvement!
