When you are easily awakened from slumber when temperature changes and can feel your sweat start to trickle, you are a hot sleeper. If so, what you sleep on plays a significant factor in your sleeping comfort. Quilts are typically made from 100% cotton or cotton blends. These fabrics are breathable, very comfortable to sleep on, and cools off the body instead of perspiring. Comforters are too thick for comfort for warm sleepers.
