Low Air Loss MattressA Low Air Loss (LAL) mattress is a specialized medical grade air mattress system designed to prevent and treat pressure ulcers (bedsores) in individuals who are bedridden or have limited mobility. It works by continuously circulating a small, constant flow of air through tiny laser made holes in the top surface of the mattress, which helps to manage the microclimate of the skin.
