Our T&N Adaptive® foam was created based on customer feedback to provide pressure relief where you need it most. The open-cell structure offers a flexible sleep surface that responds to you. The Mint Hybrid is designed to sleep cool thanks to ceramic and cooling gel, heat-wicking graphite, and the breathable construction of our Adaptive foam—plus diamond-infused memory foam that moves heat away from your body. Individually-wrapped springs provide our best motion control, while nanocoils offer personalized support and pressure relief for consistent comfort all night long. Firmer springs along the outside to create a stable edge-to-edge sleeping area ideal for all sleep positions and those who share a bed. The Mint Hybrid has a plush, ultra-soft top cover that's breathable and removable—it zips off, so it's easy to throw in the wash to keep your bed fresh and clean.
