The cushion is one of the various factors that is related to inconvenience in using of the chair. This study measured the Body Pressure Distribution(BPD) to compare convenience between new and old air cushion chair and a response for the test. The body pressures of 21 male subjects were measured under the same posture to minimize the influence of variables. The Flexible Body Pressure Mat System was used to measure body pressure of subjects. The result showed that the distribution pattern of body pressure for new product is symmetrically centering around the ischial tuberosities and the highest body pressure was less than old product.
