ABSTRACT:
A seat cushion employing the benefit of a foam cushion and alternating pressure air cushion. An air bladder reservoir with vertically extending fingers is located beneath a foam core with vertical holes. The vertically extending fingers are aligned with the vertical holes of the foam core. The air bladder reservoir and vertically extending fingers are inflated and deflated by a compressor system which provides alternating timed pressure. When inflated, the fingers protrude through the holes in the foam core beyond the top surface of the foam core. A method for fabricating the vertically extending fingers includes a cloth material coated in silicon.
