This “Za-isu” legless chair for the home was created by leveraging the skills and experiences the craftsman accumulated when building furniture for traditional Japanese restaurants and inns. Compared to the furniture for the restaurants and inns, which are used for about two hours at a time, this Za-isu can be sat on for a longer period of time. Much attention has been paid, such as to the resilience of the back support and seat surface, and the inclination and height of the seat surface, so the Za-isu can be sat on for hours on end without fatigue. The extra height to the seat surface gives users the freedom to stand up smoother especially after sitting with their legs crossed. It also reduces burden on the waist even when sitting with the legs stretched out. As rattan has inherently been a highly air permeable material, roughening the mesh helps to eliminate sweatiness, so it can be sat on comfortably for a long time. And naturally, it has been carefully created so it will not damage the straw tatami floor, even when it is placed on directly.
