This all-steel chair features rugged, durable construction. If you are looking for a basic chair that will last for years, this is the chair for you. Saddle caps on top of the rear legs are cupped to receive the front legs, ensuring lateral rigidity and downward support. The exclusive Y -frame design with patented hinge places the legs at a wide, stable angle and makes the chair practically indestructable with normal use. A unique spacer keeps the folding seat from rubbing and wearing through the leg finish. Triple welded brace strengthens and stabilizes the rear legs. Exclusive DuraFuse, environmentally safe, polymer finish resists scratches, nicks, and abrasions. Heavy-duty 7/8 In. tubular steel is extremely strong but light in weight. Polyethylene foot caps slide easily but will not mar the floor. Extra-wide 16 In. x 16 In. seats and oversize backrests make this chair more comfortable for all users.
