A cushion pad adapted to be used in a vehicle seat, the cushion pad being made of urethane foam and integrally molded, has an upper surface layer 2 having viscoelastic property (tan δ) of 0.065 to 0.144 at 36°C and at a frequency of 1 Hz, and a core layer having viscoelastic property (tan δ) of 0.052 to 0.102 at 36°C and at the frequency of 1 Hz. A ratio of the viscoelastic property (tan δ) of the core layer 3 at 36°C and at the frequency of 1 Hz to the viscoelastic property (tan δ) of the upper surface layer 2 at 36°C and at the frequency of 1 Hz is in a range of 0.7 to 0.8.",
