14-inch hybrid mattress with a medium feel, built to sleep cool for sleepers of all styles. Eco-friendly AeroFlex Talalay latex, slightly firmer than memory foam with superior breathability, pairs with OmniPhase phase-change material on the top layer to absorb and release heat, and Plush CoolSync foam contours with cooling gel. 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.
