I was very excited about this product, but it does not live up to its promises. I really cannot tell a difference in the temperature. I figured it would at least be noticeable. The bed itself is comfortable, but about the same as my previous Tempurpedic bed. When I tested the bed, I was told that I wouldn't be able to tell a difference until I was in bed for a while, so it's not even like I could have known. Anyway, I wish I knew that the cooling feature was kind of a joke before I made the investment.
