Discover next-level cooling and support with the Serta iComfort® AIR Hybrid Medium 11.5" Mattress—perfect for hot sleepers and comfort lovers alike. Engineered to promote all-night breathability, this Serta mattress combines pressure relief with advanced airflow to keep you cool, comfortable, and supported from dusk till dawn. At the core of its design is the Serta CoolFlow AIR System, a powerful airflow technology that reduces heat buildup and maximizes ventilation, creating a refreshingly cool sleep environment. Wrapped in CoolFlow Fabric, the surface offers a cool-to-the-touch feel that helps regulate your body temperature the moment you lie down. Inside, CoolFlow Gel Memory Foam enhances breathability with unique airflow pockets, allowing air to circulate freely through the mattress. For added support and cooling, Perfect Conform™ Memory Foam uses graphite-infused material to provide targeted pressure relief while drawing heat away from the body. Beneath it all, 5 ZoneResponse™ Foam delivers zoned support where you need it most—aligning your head, shoulders, back, hips, and legs for a more restful, balanced sleep. Whether you're a back sleeper, stomach sleeper, or someone who loves a mattress with cooling technology, the Serta iComfort® AIR Hybrid Medium 11.5" Mattress delivers the comfort and climate control you’ve been dreaming of.
