Very disappointment with this topper.  At first, feels great and the cover it came with was nice too. Lays great and fits great but once trying to sleep topper  did not keep cool, it seemed to retain heat. I also felt every move my husband made and he felt all of mine. I had to get up and sleep in the guest bedroom.  We will be using this topper in the pull out bed. Really wanted to enjoy this topper.  A waste.
