How Alternating Pressure Mattresses Work
Alternating pressure mattresses use rows of air-filled cells that inflate and deflate in a gentle cycle. This creates shifting support across the body, helping reduce prolonged pressure in one position and providing a more comfortable surface for long-term bed rest.
