Abstract
Abstract The present invention is directed to a chair construction and a method for fabricating such a chair. At least a portion of the chair frame is adapted to be upholstered with a removable decorative cover, and that portion -- or a component thereof may, comprise a shell having a mounting flange and a groove extending around the perimeter of the shell in substantially parallel relation with respect to the mounting flange. A bumper embraces the mounting flange and presents an anchor rib that is received within the groove. The configuration of the exterior of the bumper as well as the anchor rib cooperates with the shell to prevent inadvertent removal. A cover overlies the shell and is secured to the bumper by hidden stitching. The cover may be infolded within the resilient cushion material interposed between the cover and the shell to present one or more decorative grooves and to preclude stressing the stitching by which the cover is secured to the bumper.
