The amazingly comfortable 1100 Series Polyfold Fan-Back Folding Chair offers the perfect solution for both indoor and outdoor seating events, such as meetings, graduations and receptions. This light-weight, institutional-grade chair was made to provide you with the strengths of metal and all the benefits of plastic. The powder-coated, 18-gauge tubular steel frame features three double-riveted U-braces, one in front and two in back, to securely support the double-hinged legs. The large seat and backrest are made of comfortable contoured, color-impregnated plastic to prevent fading and rusting. The attractive radius fan-back provides ergonomic comfort and breathability to provide relief during long presentations. Color-coordinated V-tip stability plugs provide added reinforcement at the frame's junction and matching replaceable glides prevent floor damage. These stack horizontally up to 26 chairs high. The 1100 Series meets MAS Certified Green and ANSI/BIFMA standards.
