Rejuvenate your mattress with the enhanced support and refreshing comfort found in the reversible memory foam mattress topper. The dual-layer construction allows you to choose between two sides of support. One side consists of plush AeroFusion memory foam to offer supportive spinal alignment and relieve pressure points, and the other is infused with gel to promote heat dissipation. The opposite side features five zones of convoluted foam to evenly distribute body weight and provide the correct amount of support for each section of the body while allowing for maximum airflow. The odor-free memory foam meets Certifier-US standards for content, emissions, and durability for long-lasting comfort. Each mattress topper is backed by a 5-year limited warranty.
