McKesson Mattress Overlay Pad is made of convoluted foam to help reduce pressure and promote air circulation. The Decubitus Care Pads are designed to help decrease the risk of pressure sores and tissue breakdowns. The foam pad maximizes comfort using strategic cushioning on pressure points. These mattress pads are great for before or after surgery, for nursing homes or long-term care facilities, and for elderly people who might be subjected to bedsores.
