The present invention provides a soft polyurethane foam molded article (1) that has a mounting surface (1A) and is obtained by foam-molding a foaming stock solution. The soft polyurethane foam molded article (1) includes a plurality of layered parts (11 and 12) that form layers in a vertical direction (Y) perpendicular to the mounting surface. A plurality of foaming cells included in each of the layered parts have a ratio of a size in a lateral direction (X) along the mounting surface with respect to a size in the vertical direction that becomes larger as the foaming cells become positioned closer to the side of the mounting surface (1A) in the vertical direction. At boundaries (C1 and A2) between the layered parts adjacent to each other in the vertical direction, the ratio of a foaming cell included in the layered part (11) on the side of the mounting surface is lower than the ratio of a foaming cell included in the layered part (12) on the side of a back surface (1B) opposite to the side of the mounting surface.
