1. A seat cushion comprising:
a second air cell section that is located on a rear side of a seat surface;
a third air cell section that is located rearward of the second air cell section; and
a control unit configured to cause the second air cell section and the third air cell section to be alternately decompressed,
wherein the second air cell section and the third air cell section are adjacent to each other and have a common boundary extending diagonally in a front-rear direction of the seat surface such that an ischial region of a user fits in the boundary
wherein the control unit is further configured to perform decompression to cause ventilation to occur through a groove formed in a base material of the seat cushion and a slit between the second air cell section and the third air cell section located inside a position corresponding to the boundary.
