The aim of this study was to develop a new kitchen stool that doesn't move away during one's sitting. At first, we analyzed the mechanism of the sitting motion, and found that the moving away of the chair was caused by the horizontal load given by the thigh which appears maximum in the early phase of sitting. On this fact, we designed a new structured caster, which has a special break system inside. In this caster, the break is effective under low or no load condition, and ineffective under the load larger than a particular value. To design this switching load value, we analyzed the horizontal and vertical element of the load which changes depending on the sitting stage, and differs for five casters. As a result of those studies, we designed a new caster breaking system, which achieves both stability for sitting and mobility for kitchen work.
