To stably hold a user's body and effectively disperse body pressure, and to correspond to a plurality of purposes of use.

A pad body 12 is composed of a first pad portion 20 and a second pad portion 30 which are formed of different elastic materials and have different hardnesses, and outside surfaces 22 and 32 of the respective pads 20 and 30 form a body holding surface 14. When body weight of the user is applied on the pad body 12, different deformation degrees of the first pad 20 and the second pad 30 make the body holding surface 14 deform along the body shape of the user to hold the body and disperse his/her body pressure. The second pad 30 allows its positional displacement to the first pad 20 with connection members 40 as the center of hinge, and is used as a seat cushion or the like besides as a body posture holding pad.
