Receive optimal targeted body support when resting on 3 zones of comfort found in the 3-inch Zoned Memory Foam Mattress Topper. Pressure-relieving AeroFusion memory foam found in the head and foot zones provides plush support while containing micro-channels that allow added air flow and temperature regulation to help you sleep more comfortably throughout the night. The middle torso zone consists of firmer gel-infused AeroFusion memory foam that combines the pressure-relieving and breathable properties of AeroFusion memory foam with a cooling gel infusion. The three zones work together to offer support while gently cradling the body to relieve pressure points and enhance spinal alignment. Also included is a luxury circular-knit cover that adds a layer of smooth softness and features a thin layer of memory foam quilted directly into the top to offer seamless, soft comfort. The non-skid bottom fabric ensures the topper will stay in place atop your mattress night after night. The odor-free memory foam meets CertiPUR-US standards for content, emissions, and durability for long-lasting comfort.
