What Is a Cool Side Pillow
A cool side pillow is a pillow designed to stay cooler than standard pillows while you sleep on your side. It usually uses breathable covers, open-cell foams, or phase-change materials that pull heat away from your head and neck. The goal is to reduce heat buildup and help maintain a comfortable sleep temperature.
Common Materials and Features
Many cool side pillows use gel-infused memory foam, latex, or open-cell polyfoam that promotes airflow. Some models include phase-change material liners that absorb and release heat. Breathable, moisture-wicking pillowcases and removable, washable covers are common features. These elements help manage warmth without changing the pillow’s support profile.
How to Choose the Right Cool Side Pillow
Side sleepers should look for a pillow with enough height to keep the spine aligned while keeping the head cool. Check the fill material, cover fabric, and whether the pillow is designed specifically for side sleeping.
