Abstract:
The specification discloses a contoured, molded plastic shell chair whose exterior shell is segmented into arm, back and seat shell segments so that, while each segment is contoured somewhat, each segment is free of any sharp contours. Each segment is separately upholstered by an unseamed upholstery segment. The chair body is supported on a base secured in a recess in the bottom of the seat segment of the chair shell. The upper portions of the base are hidden by a plastic cover secured to the bottom of the chair. The cover includes an aperture through which the supporting post of the base passes and preferably a slot from the aperture to the cover periphery so that the slightly flexible cover can be opened and slipped around the supporting post of the base.
