The ATHENA mattress features phase change technology that provides cool-to-the-touch fabrics to adjust to your body's temperature for a refreshing surface. Talalay latex adds a natural and durable layer of pressure relief and breathability. High-density comfort foams provide strength and durability, with a quantum-encased coil unit that provides dynamically responsive support. Advanced Comfort Edge expands the sleep surface and supports the seating edge. Finally, the mattress is hand-tufted for 20 times for superior comfort.
