The mounting frame is made of aluminum alloy. Each of the air cushions is made of rubber material. The controller regulates the air pressure in each of the air cushions so as to adjust hardness and tension of each of the air cushions. Thus, the air cushions have different curvatures and profiles so that when the air cushions can be used to support a user's head, neck, back, hands, waist, hip and legs so as to provide a comfortable sensation to the user.
