The material and technique used for construction are exactly the same as those used for the Stackable Chair. The steel tubes of the square part are also welded together, and the corners are also left visible. The back is made extra noticeable by the use of a subtle decorative element: a big screw with a round, flat head which connects the seat to the frame. The Office Chair is available in a wooden or upholstered version. It has a mechanism to adjust the height beneath the seat. Seat and backrest: wood covered with Kvadrat Polo (RAL colors 7035 / 9010 / 5024) and fitted with a large, decorative screw. Frame: epoxied steel. Dimensions: 52 x 44 x 82.
