Review (3/5): Gel moves to one side - stays cool for a few hours
It does stay cool for a few hours but if you sleep on it then it actually heats up. Another thing that is annoying is the gel moves to one side of the pad so you have to smash it out once in a while. It does this after being either laid upon or if you have it upright against your back. I think it needs individual stitched squared for the gel so it doesn't move around as much. Works ok for the price but doesn't keep me cool enough at night like I wanted.
