Add cool and supportive comfort to your bed with the SensorPEDIC SensorCOOL 3-Inch Memory Foam Mattress topper, featuring a 1-inch quilted layer of gel-infused SensorAIR memory foam that helps you sleep cooler while cradling the body atop a 2-inch layer of open-cell, gel-infused memory foam that is tested to sleep cooler than traditional foams and offers supportive pressure point relief for a more comfortable night's rest. This topper features the built-in, ventilated iCOOL Technology System that enhances air flow and ensures optimal breathability in the foam, fabric, and fabrication processes. The luxurious circular-knit fabric cover adds a layer of smooth, breathable softness, while the stretch-to-fit bed skirt fits deep pocket mattresses up to 18-inches deep to ensure this topper stays securely in place night after night.
