The Protekt 500 with (VGPT) Visco Gel Polymer Technology is a revolutionary support surface that provides unprecedented pressure redistribution, rapid heat dissipation, and vast increases in breathability compared to traditional foam. Visco Gel Polymer Technology works by allowing air to pass through open cells, channeling it away from the body instead of trapping it within the closed cells of standard memory foam. The infusion of gel polymers throughout the foam contributes both cooling properties and the virtual elimination of static fatigue. The heel section of the Protekt 500 provides unparalleled pressure mapping results. Designed to guard the vulnerable heel area from incapacitating reoccurring pressure ulcers. Optional Raised side rails reduce risk of falls and increase patient safety by providing a firm perimeter for egress and ingress.
