Abstract
The objective of the present invention is to provide: a cushion cell with a new structure which is designed to disperse stresses when the cushion cell is in an inflated state such that excellent durability is achieved and in which a large support area for the human body can be obtained with excellent space efficiency relative to a square shaped space for disposal in an inflated state; and a cushion body with a new structure using the same. The cushion cell is formed with a fluid chamber inside and the height of the cushion cell can be changed by adjusting the pressure in the fluid chamber. The planar shape of the cushion cell in a deflated state is a square shape, and each side part has a curved shape protruding outwards.
