• arranging a pressure receiving member between the plurality of side frames in the seat width direction and attaching the pressure receiving member to the seat frame, wherein the pressure receiving member includes a wide portion having a first width in the seat width direction, a narrow portion having a second width in the seat width direction that is smaller than the first width, and an upper support portion, wherein the narrow portion extends to a lower end of the pressure receiving member with the second width;
• arranging a side air cell at a position that aligns with the wide portion of the pressure receiving member in a longitudinal direction in which the plurality of side frames extend, and attaching the side air cell to at least one of the plurality of side frames;
• disposing the upper support portion of the pressure receiving member above the side air cell and in an inner side of the side air cell in the seat width direction;
• and
• arranging a bag at a position that overlaps with the upper support portion of the pressure receiving member as viewed from a front, wherein the bag forms a shoulder support portion that is configured to support a shoulder of a seated passenger of the vehicle seat.
