The comfortable 1300 Series Premium Upholstered Folding Chair is made with a combination of durable vinyl wrapped over 1.25" of soft foam on a sturdy metal frame. This institutional-grade chair features a unique full-size, double-contoured backrest, upholstered and firmly secured to the frame with six rivets. The powder-coated steel frame is made from heavy-duty 18-gauge round tubing and features three U-shaped double-riveted cross-braces, one in front and two in the back, to securely support the double-hinged legs. Color-coordinated V-tip stability plugs provide added reinforcement at the frame's junction and matching replaceable glides prevent floor damage. The 1300 Series meets MAS Certified Green and ANSI/BIFMA standards.
