Full rubber wood construction and a 440 pound load rating give this set of four unusual margin for a chair without upholstery, and the hollowed backrest keeps the shoulders cool during a long meal. The ergonomic back shape supports posture, additional crossbars firm up the seating experience, and protective corners take the edge off sharp lines. A splinter-free surface makes maintenance effortless, needing nothing more than a damp cloth. Each chair measures 21 by 16.5 by 35.5 inches with a 17.5 inch seat height and weighs about 12.5 pounds. Assembly is required.
