US 5,490,717 A · Lotus seat

Abstract

A seating device is disclosed that offers comfort in use over extended periods of time and certain therapeutic effects as well as being readily portable and storable when not in use. The device is embodied in an inflatable seat that may be molded from thin, clear polyethylene/vinyl plastic material and formed with a flat thicker bottom surface, a concave seat area, a rising rear support, and a smaller frontal post section. The concave seat area is formed with an inherent forward tilt design which automatically aligns the spine of a user while the rear support provides additional comfort. The smaller frontal post section prevents forward sliding on and ride up of the rear of the seat. A valve is located in the bottom surface for inflating and deflating the seat and a snap strap may be provided for permanent closure after deflation and folding of the seat into itself.
