Abstract:
A flexible polyurethane foam molded article includes a plurality of layer parts (L1 to L10) that are layered in a vertical direction (Y) perpendicular to a stage surface (1A). When the entire flexible polyurethane foam molded article is compressed by 15% in the vertical direction (Y), the front surface layer (L1) positioned closest to the stage surface (1A) in the vertical direction (Y) among the plurality of layer parts (L1 to L10) has the lowest residual thickness ratio in the vertical direction (Y) among the plurality of layer parts (L1 to L10). When the entire flexible polyurethane foam molded article is compressed by 50% in the vertical direction (Y), the back surface layer (L10) positioned closest to a non-stage surface (1B) of the flexible polyurethane foam molded article in the vertical direction (Y) among the plurality of layer parts (L1 to L10) has the highest residual thickness ratio in the vertical direction (Y) among the plurality of layer parts (L1 to L10).
