I bought this gel memory foam mattress topper hoping for an upgrade from our previous regular memory foam topper (also purchased from Overstock) which had reached the end of its lifespan and was starting to break down, The mattress topper is comfortable enough, but I don't see any advantage to the gel foam over traditional memory foam. One of the things it is supposed to do is dissapate body heat better. My husband sleeps really hot. He sweats quite a bit and this can leave his side of the bed kind of damp in the morning - gross, I know. I was really hoping the gel memory foam would be cooler, or at least distribute the moisture so I don't slide my leg into it after he gets up. It doesn't. Neither of us have noticed any difference.
