Wake up refreshed on the Bel-Opedic Serenity 13" Firm Hybrid Cooling Mattress. Designed for sleepers who love a supportive, hotel-style feel, this mattress combines cooling comfort foams with a responsive pocketed-coil core to keep your body aligned and your night peacefully cool.

On top, a knit cooling cover helps draw excess heat away from your body so you don’t feel trapped in warmth. Underneath, firm 4 lb medical-grade memory foam gently contours to your curves, easing pressure at the shoulders, hips, and lower back while maintaining a sturdy, “on-the-mattress” feel that back and stomach sleepers appreciate.

Layers of Amstar-Flex™ comfort foam and compressed fiber create a smooth transition into the support system, so the mattress feels supportive without feeling stiff. At the core, foam-encased pocketed coils move independently to reduce motion transfer and provide edge-to-edge stability, making it easier to sit or sleep near the side. A durable border cover with performance icons finishes the design for a clean, modern look that fits effortlessly into contemporary, minimalist, or transitional bedrooms.
