Abstract
A one piece air mattress suitable for use in health care settings to aid in prevention of bed sores has air cells permanently attached to a common base sheet along a base perimeter of each cell. The air cells and base sheet are of flexible radio frequency weldable plastic material, and all the air cells can be simultaneously welded to the base sheet in a single welding step using a special welding jig. Air supply conduits are defined by strips bonded to the base sheet in overlying relationship to orifices opening the supply conduits to the air cells, thereby eliminating the need for external air hoses and connections. An alternating pressure air mattress can be made by opening different air supply conduits to alternating sets of the air cells.
