I purchased a Cal King Beauty rest pillow top, firm. I was advised to get the extra softness of the pillow top as firm may seem very hard. I did try them out in the showroom and liked the pillow top, however when I did use it regularly I discovered the tempur pedic top was very warm and I am not a fan of hot weather and find it difficult to sleep when it is to warm. The pillow top seemed to insulate the heat in this bed and I often awoke during the night feeling uncomfortably warm. I really wish I could have read some reviews at the time as I probably would have forgone the pillow top. I do love the firmness but cannot tolerate the tempur pedic. I no longer sleep on this mattress as it became to uncomfortably warm with many nights waking sweating and then the bedding would be damp. I advise anyone who has a problem with temperature to avoid the pillow tops made with the tempur pedic material.
