NPS 200 Series Premium All-Steel institutional-grade folding chair features a heavy-duty powder-coated 18-gauge tubular frame with a 2.25-inch frame strengthener on each side of the seat. Two double-riveted U-braces - one in front and one in back - securely support the double-hinged legs. The seat is designed with a waterfall-style front for added comfort. A supportive full-sized double-contoured backrest features curled safety edges and is electromagnetically tack-welded to the frame. Color-coordinated V-tip stability plugs provide added reinforcement at the frame's junction and matching replaceable glides prevent floor damage.
