The Protekt 600 is constructed to provide optimal pressure redistribution and support for the high risk bariatric patient. The mattress was designed utilizing a combination of the highest density foams to create the quintessential sleeping surface for the heavier patient. Top-layer of high resilient high density die cut foam provides optimal support and comfort. Heel section is made of Lura-Quiltfoam, an aerated foam, which allows air to continuously pass thru keeping the patient cool and dry. Bottom layer of foam is constructed of ultra high density high resilient foam which provides unprecedented patient support and stability. The top of the cover is a four way stretch nylon material with a low moisture-vapor transmission rate. Water resistant anti-microbial/bacterial cover is perfect for infection control. Anti-Contamination Flap covers the zipper reducing the possibility of fluids contaminating the foam core.
