Each of these sturdy 19-3/8" wide x 18-1/4" deep x 29-58" high (when unfolded) folding chairs feature a curved metal backrest, solid tubular steel frame with riveted U-braces between front and back legs, smooth hinge folding operation, and protective end caps on legs to help protect floor surfaces. Their lightweight folding design allows easy setup and compact stacking and storage. All-weather, stain-resistant, powder coated finish makes them easy to clean. Chairs are packaged and sold in cartons of four, but with their economical pricing, you'll want to order all you could need and then some to provide extra seating for office events such as conferences, meetings, presentations, parties and primary seating for lunch areas. Chairs come ready to use with no assembly required.
