Gel Mattress Overlay for hospital beds, 76 x 34 x 3.5 inches, with a 300 lb weight capacity and Medicare code E0185 designation. This overlay sits atop an existing mattress and maintains alignment through four elastic corner straps that secure it in place during patient transfers. Key construction features include full-length head-to-toe gel bladders that reduce bottoming out and pitting on the underlying surface, and a convoluted egg-crate top layer designed to distribute pressure along the entire length of the body. The outer cover is a urethane-coated nylon that is water resistant yet vapor permeable, while the vinyl base offers waterproofing and stain resistance. Designated head and foot sections provide orientation guidance for installation and use. Compatibility and use: designed to fit standard hospital bed mattresses with secure attachment via corner straps. Care and warranty: the product includes a 1-year limited warranty on both the cover and the mattress component. This overlay is suited for extended care settings and patients requiring a gel-support surface over their existing mattress.
