An air pressure control device of a vehicle seat includes: a bulging shape forming unit configured to form a bulging shape on a seat surface by expanding air bags configured to be provided inside a seat; a bulging shape moving unit configured to move a position of the bulging shape formed on the seat surface by each corresponding air bag by sequentially expanding and contracting a plurality of air bags aligned in a direction along the seat surface in an arrangement direction of the air bags; and a pumping capacity adjusting unit configured to increase a pumping capacity of an air pump that pumps air into each air bag as a protrusion amount of the corresponding bulging shape increases when a formation position of the bulging shape is moved.
