ABSTRACT:
An integral inflatable cushion comprises a flexible bottom wall and a plurality of upstanding air cells having flexible generally vertical side walls, said air cells being substantially pyramidal in shape and having a substantially rectangular flexible lower section defined by the vertical side walls and sealed to the bottom wall, and a flexible domed tapered top area connected to the vertical side walls, the side walls of adjacent cells being separated and spaced apart to define lateral and longitudinal paths and being independently upstanding when inflated, and tubing connected to the air cells through the bottom wall to adjust and monitor the air pressure in the cells from beneath the cushion.
