Foam-filled bed mattress overlay

Foam-filled bed mattress overlays are reusable pads designed to sit atop existing mattresses, spreading body weight evenly across a larger surface. Clinically, they help reduce pressure on vulnerable areas—such as hips, shoulders, and heels—to prevent or alleviate pressure ulcers (bedsores), particularly for immobile patients, elderly individuals, or those with limited mobility or low body mass.

These devices are typically regulated as medical devices based on their intended use for pressure relief, though classification varies by jurisdiction. They are generally supplied as standalone overlays, compatible with standard mattresses, and may require periodic cleaning or maintenance to ensure hygiene and effectiveness.
