At its core, Beautyrest’s exclusive T2 Pocketed Coil® system provides targeted support and minimizes motion transfer, making it ideal for undisturbed sleep. Layers of advanced foams, including Dynamic Response™ Memory Foam and AirCool® Foam, contour to your body while promoting airflow and temperature regulation. The addition of RightTemp™ Wave Foam enhances pressure relief while maintaining a cool, comfortable feel.

The surface features InfiniCool® technology for added cooling and cleanliness, while the sustainable fabric cover—made from recycled ocean plastics—reflects a commitment to both comfort and environmental responsibility. Built for performance and durability, this mattress offers a refined balance of firmness, support, and cooling innovation.
