A polyrotaxane is blended into a polyol composition, which can reduce the tensile stress of a flexible polyurethane foam. A vertical compressive stress due to the weight of a sitting user and a tensile stress due to the input of lateral vibrations act on a urethane pad. However, by reducing the tensile stress of the flexible polyurethane foam, the direction (inclination) of a resultant force obtained by combining the compressive stress and the tensile stress can be brought close to the vertical direction. Thus, the angle of inclination of the user's hip (ischium) on the urethane pad to the vertical direction due to the input of lateral vibrations can be reduced, so that the sense of wobble of the urethane pad can be reduced.
