Luxury sleep support with recovery in mind, Bedgear’s S3 Performance Firm Memory Foam Mattress conforms to your body, relieves pressure points, and keeps you cool with cross-ventilation. Designed in the USA, this foam core mattress in a box for hot sleepers feels cool-to-the-touch with the heat-deflecting Ver-Tex® cover, and breathable Air-X® mesh side panels circulate air from the ventilated layers. Promoting deeper sleep and brighter days— the React+ comfort layer infused with cool gel beads cradles and increases airflow while the ventilated React® core of high-density memory foam regulates temperature with firm full-body support.
