This sleep surface is inspired by the minimalist approach to sleep found in places like East Asia, while including a more modern mattress design. Enjoy relief from back pain with a sleep surface that helps you achieve a neutral spine while also aiding proper blood circulation and better oxygen intake. The firmest mattress available, guaranteed. (Available with an optional sewn-on cooling cover from high-tech PE fibres.)

Very nice mattress. Mattress is VERY firm and we are using the less firm side. Wound up putting our existing 2 inch foam topper on it which made it perfect for me. Fast shipping too.. Jennifer. Rockledge, FL. Mon Jul 13 2026
