Made for true efficiency and stability, these 600 Series Folding Chairs are blow-molded, resin-plastic folding chairs that feature a heavy-duty, powder-coated 19-gauge tubular frame and a large contoured seat. They also have a backrest for added comfort. Two cross braces, both in front and in back, provide extra support. V-tip stability plugs provide added reinforcement at the frame's junction and replaceable glides prevent floor damage. Lightweight for easy transport, they are stain-resistant and perfect for easy set-up and take-down, indoors or outdoors. The 600 Series meets MAS Certified Green and ANSI/BIFMA standards.
