Odyssey® Elite Mattress: Medline’s Odyssey® Elite Mattress uses five zones to increase comfort and maximize function. Visco-Elastic conforming top layer helps reduce pressure and prevent friction. Flame retardant, antimicrobial, fluid-proof top cover minimizes friction to help prevent skin shear. Full seven-year warranty. Each of the Odyssey® mattresses is designed with an advanced center layer. Five different zones of anatomically designed dye cuts help minimize pressure and skin shear from head to foot. On the Elite model, a super-conforming layer of Visco-Elastic foam cradles the fragile bony prominences of heels and ankles. With Elite, Zero-G, High-Res, and Extended Care Mattresses, smaller cuts in the trunk help lower shearing forces while providing skeletal support. The advanced design helps the Odyssey® line promote good posture while relieving pressure and providing comfort. The entire Odyssey® line features inverted side seam seals top and bottom to provide superior protection against fluid penetration. Brass vents allow the mattress to breathe. Slip-resistant vinyl bottom material withstands day-in, day-out institutional use. 36″ x 84″ x 6 ½” with Fire Barrier.
