A pneumatic control device for a vehicle seat includes a forcible-delivery control unit, an opening-closing control unit, and a residual pressure release control unit. The forcible-delivery control unit drives an air pump to forcibly deliver air to an airbag, which is provided in a seat. The opening-closing control unit opens and closes an inlet valve, which is provided in a passage of the air. The passage is in communication with the airbag. The residual pressure release control unit opens an outlet valve provided in the passage on an upstream side of the inlet valve after driving of the air pump is stopped, thereby releasing the air sealed on the upstream side of the inlet valve in a closed state from the passage.
