The PinCare Gel Mattress Overlay for Hospital Beds is a gel flotation mattress surface designed for individuals with back pain and those who are at risk for pressure ulcers. This overlay combines the softness of foam with the effectiveness of gel in distributing weight and pressure over a larger area. The mattress consists of the PinCare Pad, a soft foam overlay of small finger-like projections; a gel-foam core; and a layer of polyurethane foam. This overlay is covered in a Staph-Chek Fusion Fabric Cover. DIMENSIONS (WxDxL): 35 x 3 x 80 inches. The foam base is 3 inches thick.
