This chair is uniquely designed to be stronger than traditional single-piece chairs without the disadvantages of most two-piece chairs. The large ergonomically designed seat has a waterfall front making it comfortable for children and adults alike. The chair can be stacked or turned over on desks and tables. The specially designed matching 1½" polypropylene ball glides will not wear out, mar floors, or rust. The durable powder-coat color finish on the frames will stay looking bright and new. With the heavy duty legs and twin tube back supports having been mig welded, this chair is the finest in the industry. It is available in your choice of 12 mix-and-match seat, back, and frame colors that coordinate with all Mahar storage units and tables. All chairs are shipped fully assembled and are proudly made 100% in the U.S.A.
