National Public Seating Premium triple brace folding chair in black color holds up to 480 lbs of moving weight and has color coordinated polypropylene glides for protection of floor surface from scratches.
The strongest in its class, our 300 Series premium all-steel institutional-grade folding chair features a heavy-duty powder-coated 18-gauge tubular frame with a 2 1/4″ frame strengthener on each side of the seat. Three double-riveted U-braces – one in front and two in the 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. The 300 Series meets MAS Certified Green and ANSI/BIFMA standards.
