The characteristic zig-zag line from the stile to the rear leg brought a new design in creating innovative chairs. To reduce the amount of material and cost, a chair is designed to have a shape that uses a primary board (solid wood board to cut out legs) that is as small as possible since the stile and rear leg are made out of one solid wood material. At first glance, the shape of this chair may seem to require a large wood piece. However, we found an effective method in producing this chair that cannot be identified by its appearance.
