Abstract

A chair including a backrest and a chair seat is disclosed. The back rest and the chair seat are preferably constructed from blow-molded plastic and an opening or hole may be disposed through a portion of the chair. The opening is preferably formed in the backrest and the opening may extend completely through the backrest. Advantageously, the opening may form at least a portion of a handle and the opening may be formed during the blow-molding process. The chair may also include a frame and one or more legs that support the chair seat and backrest above a surface such as the floor or ground. In addition, the chair may include a first groove formed in the lower portion of the chair seat and a second groove formed in the lower portion of the chair seat, and a first crossbar may be at least partially disposed within the first groove and a second crossbar may be at least partially disposed within the second groove. The crossbars and/or grooves may be sized and configured to increase the strength and/or rigidity of the chair seat.
