13-inch hybrid mattress with a medium-plush feel for all sleep styles. A tufted cover of polyester and TENCEL lyocell with a channeled sidewall sits over convoluted memory foam that boosts airflow and cradles pressure points, plus deep layers of high-density foam that distribute weight evenly. Individually encased steel pocket coils limit motion transfer, with thicker-gauge outer coils for durable edge support. The CertiPUR-US certified foam arrives rolled and compressed in a single box. Covered by a 10-year warranty.
