Drive Medical's Gravity 7 Long-Term Care Pressure Redistribution Mattress uses multi-layered high-density foam to provide optimal pressure redistribution for individuals in long-term care facilities. The top layer of foam is highly resilient and die cut, providing comfort and proper pressure redistribution. The ultra-soft heel section is uniquely designed to provide extremely low skin interface pressure, preventing pressure ulcers. The stretch mattress cover features 2-way, water-resistant, vapor-permeable nylon for improved comfort and hygiene. The cover provides a low moisture transmission rate (MVT), keeping the patient cool, dry, and comfortable. Backed by a 7-year limited warranty foam and 3-year limited warranty on cover from Drive Medical, a leading brand of mattresses and other medical goods for more than 20 years.
