Contoured backrests shaped to follow the body make this set of four comfortable through the long meals it is built for, and the gray polyester upholstery over high-density sponge stays breathable and tear resistant. Solid rubber wood delivers strength, and widened support legs measuring 2.2 inches add stability under a load rating of 375 pounds per chair. Each chair measures 20 by 19.5 by 31.5 inches with a 19.5 inch seat height and a 19.5 by 18 inch seat, and weighs about 16.5 pounds. The set requires assembly.
