PURPOSE: To provide a user with a desirable comfort level by letting the user to automatically re-form the shape of a load receiving face corresponding to actual pressure distribution applied on the load receiving face such as a sheet, a bed, etc. CONSTITUTION: Plural pressure sensors 14 are arranged in a load receiving face. The pressure sensor 14 produces data expressing actual pressure distribution effected on the load receiving face by a user. A processor 40 compares partial load of total load applied on each of plural ranges of the load receiving face and a range desirable for each section. When the partial load is not within the desirable range, a servo mechanism 28 is actuated to adjust the quantity of air in an air bag 20 equipped inside a load receiving face 12 to change the shape of the load receiving face 12 so that the partial load on each section is within a desirable range. |
