" Description Provide proper pressure redistribution and comfort using The Drive Medical Gravity 7 Pressure Redistribution Mattress. It is a cost-effective option for your long term care needs. It has three full layers of foam to maximize comfort and pressure redistribution. The top layer features a die-cut section and memory foam heel section to target pressure redistribution zones, while the bottom layer has full-length, horizontally-scored articulation cuts, which helps keep the mattress durable for longer. The high-density foam perimeter ensures that transferring out of this mattress is simple and safe. The Gravity 7's stretch cover features a low shear design which is fire retardant, fluid proof, tear resistant and a breeze to clean. The optional elevated perimeter and cut-outs have two benefits: The elevated perimeters help to keep the user from falling out of the bed, while the cut-outs assist the user in getting off the bed when transferring.
