In this paper, we consider a new type ofa mat to prevent bed sores for disadvantaged people. This mat is made of 16 actuators. Each actuator has a sponge that is coated with a cloth and an airtight bonding sheet. Further, when air is charged into the actuator, the stiffness of the actuator can be controlled. At this time, the shape of the actuator is hardly changed by the inner pressure. Therefore we divide these actuators into 2 groups. That is to say, one is a compressed group and the other is decompressed group. Thus, the mat can change the contact pressure distribution that acts to the body by using these groups. Since it is reported that blood flow is prevented under the condition that the contact pressure of seating face is over about 32[mmHg], we measure contact pressure at moving of the mat. From some experimental results, it is cleared the contact area of over 32[mmHg] can decrease from 23.2[%] to 2.9[%] for moving.
