I purchased the pillow and mattress protectors for my Temper-Pedic Luxe Breeze Mattress and Pillows and they make my husband and I extremely warm and never feel the cooling. They seem to put a barrier between you and the mattress and again the pillow so defeat the purchase of buying a ( very expensive) cooling mattress. We are both very unhappy with the fact that we want to put protectors on the bed and pillows but nothing seems to work.....
