Pressure relief mattresses are the first step in preventing and treating pressure ulcers. These pressure relief foam mattresses are designed to replace the traditional hospital innerspring mattresses that are often very uncomfortable. A zoned or multi-zoned mattress is important because human bodies are heavy in some places and lighter in others. Pressure zoned mattresses take this into account and redistribute pressure accordingly. Zones with special patterned die cuts into the foam help reduce shear and friction. The added heel zones with slopes and/or special materials or designs help assure the heels are being well perfused (supplied with adequate blood flow). Included in this section are a wide range of pressure relief mattresses for various patient weights, levels of prevention, and budget. Free fast shipping.
