Cushioning pads made of convoluted synthetic foam that are designed to reduce pressure on specific areas or the whole body. These pads consist of synthetic foam (e.g., polyethylene) that is manufactured using a process that usually involves the saturation of the plastic material with a thermosetting resin. This creates a convoluted surface with waves and boxes (e.g., egg-crate-shaped) providing good cushioning and air circulation. Dedicated convoluted foam pressure relief pads are available in a variety of shapes and sizes. They are mainly used to distribute localized pressure to larger body areas, especially to prevent or alleviate pressure sores. The pads are frequently used on top of chairs, wheelchairs, tables, and beds.
