12-inch hybrid mattress with a firm feel, combining breathable AeroFlex Talalay latex, slightly firmer than memory foam, with contouring CoolSync foam. Zoned pocket coils add targeted support and motion control, while a HyperChill cover helps keep sleep cooler. The flexible base foam works with adjustable bases, and the CertiPUR-US certified foam arrives compressed, rolled and boxed. Covered by a 10-year warranty.
