The DynaRest Premium Visco-Gel Infused Foam Mattress is a multi-layer mattress featuring variable density foam providing optimized pressure redistribution and rapid heat dissipation. This pressure redistribution mattress uses visco-gel infused memory foam to offer superior protection and prevention of bed sores and pressure ulcers. The middle layer features air channels allowing air to pass through open cells in the foam, while channeling heat away from the body, eliminating perspiration and heat buildup. An optional raised foam safety perimeter decreases the risk of falls and increase overall patient safety by providing a firm foundation for entry and exit. 1/BX
