A Graphene-Infused Breathable Circular Knit cover has been designed to encapsulate this powerful sleep system. Graphene fibers can help reflect emitted far Infrared rays from the body at night, sending them back to the body for greater recovery during sleep. Inside the cover, layers of Ventilated, Gel-infused REM-Air memory foam and GelCare® Memory Foam team up with Individually-wrapped tempered Coils to deliver the ultimate support technology. Finally, the Hi-Response poly Base Support foam layers above, below, and surrounding the Coil section supports the body at its deepest points, helping support deeper REM sleep.
