A seat cushion pad for a vehicle and a seat back pad for a vehicle, which produce no discomfort between seat comfort of an under-buttock section and a backrest section and that of the other sections, are provided. A part of or entire seating surface except the under-buttock section of the seat cushion pad is composed of a material Q having a density lower than the density of a material P constituting the under-buttock section. The 25% hardness based on a hardness testing method specified in JASO-B408 of the material Q is smaller than the 25% hardness of the material P. A part of or entire sections except the backrest section of the seat back pad are composed of a material S having a density lower than the density of a material R. The 25% hardness based on a hardness testing method specified in JASO-B408 of the material S is softer than the 25% hardness of the material R.
