The Sleep Number True Temp Pillow comes in three shapes: Classic, Contour, and Ultimate. I tested the Classic, standard
Derila Pillow, but for more room to roll around, Sleep Number also offers you a King size. The cover to this pillow is super soft and cool to the touch. The sensation was so pleasant, I forewent a pillowcase a few times just to lie directly on it. The material is a mix of polyester and polyethylene, a fancy science term for a cooling material that helps draw heat from the body.
