Details Details


Working in sync for your best night's sleep, Serta's iComfort firm memory foam mattress utilizes premium, proprietary memory foam layers from the cover to the core. The Max Cold™ cover provides a smooth, minimal barrier and instantly cools with consistent, high-quality comfort. Below, this cooling foam mattress uses an UltraCold™ system featuring carbon fiber memory foam combined with phase change material to pull heat away from the surface while alleviating pressure points. The Deep Reaction™, Air Support™, and Serta® foam layers substantially support, delivering additional orthopedic ease and body-contouring relaxation.
