I like the Temperpedic mattress. We have it on our platform bed (an old one from Scan). I use a mattress cover and I like cotton, high-thread count sheets. Also, I do put an electric blanket on the bed in the winter. We keep our bedroom cold and the mattress can be cold; so preheating is vital. The only drawback I see with the Temperpedic mattress is that it is extremely heavy. We have a king-size bed. Therefore, the job of sheet changing is passed to my husband, along with my (sometimes) nagging as I do like fresh sheets at least biweekly.
