An alternating-pressure bed mattress overlay is a reusable pad designed to sit atop a standard mattress, featuring interconnected chambers that inflate and deflate in sequence. Clinically, it redistributes body weight by shifting pressure points, helping prevent pressure ulcers (bedsores) in immobilized patients, such as those with disabilities, low mobility, or severe medical conditions like decubitus ulcers.
These devices are typically regulated as medical products under general safety and performance standards, with classification varying by jurisdiction. They are commonly supplied as reusable hospital or home-use items, often requiring maintenance or cleaning protocols to ensure hygiene and longevity.
