I love the comfort of the Silver Chill Mattress. It contours to my body. The only issue I have is it is advertised as "Silver Chill". My husband and I do not feel the "Chill" We have both experienced a definite 'warm' sensation while laying on the mattress. We have not been able to sleep with any covers, even a sheet. I wake up during the night and my back side is warm and moist. We are not sure if we are doing something wrong.
