Alternating Pressure Overlays
Alternating pressure overlays are a more cost effective alternative to alternating pressure or low air loss mattresses, ideal for short term care. Overlays (as the name suggests) fit over your existing mattress. They are lightweight, portable, and cost significantly less than entire new mattresses.
Like alternating pressure mattresses, alternating pressure overlays utilize air cells or bladders that inflate and deflate to relieve pressure on the body. Some models also offer low air loss technology, which uses steady airflow to reduce heat, moisture and friction on the skin.
