In the mattress (10), a plurality of cells (16) are provided on the body-pressure-acting surface of a substrate (20) that supports a human body, and a pressure adjustment means (54) is provided that variably sets the height of the cells (16) by adjusting the pressure of fluid chambers (40) formed within the cells (16). A cushion layer (22) having elasticity is provided on the body-pressure-acting surface of the cells (16), a constricted section (44) is formed at the intermediate section in the height direction of the cells (16), and by means of the cells (16) undergoing oscillating deformation at the constricted section (44), the body-pressure-acting surfaces of the cells (16) are permitted to incline to track the deformation of the cushion layer (22).
