[Problem] To provide a cushion pad that reduces the wobbling feeling. [Solution] Regarding the test piece sampled from a core portion, the measured deflection under a load of 100 N during compression is equal to or less than 30 mm. The measured static spring constant under a load of 300 N at a pulling rate of 20 mm/minute is equal to or less than 25 N/mm. In the case of a vibration input in a low frequency band in the lateral direction, the compressive stress in the vertical direction due to the weight of a seated person and the tensile stress due to the vibration input in the lateral direction act on the support portion. The direction (gradient) of the resultant force as a combination of the compressive stress and the tensile stress can be closer to the vertical direction. This allows reducing the wobbling feeling.

[Problem] To provide a cushion pad that improves the holding property and reduces the wobbling feeling. [Solution] A force Sduring compression to 25% in a first portion and a first side portion, which are positioned on a seating surface side, is set to a value smaller than the value of Sin a second portion and a second side portion, which are positioned on a bottom surface side. The first portion and the first side portion are positioned on the seating surface side of a thickness center. This allows ensuring a close contact property with the buttocks. The second portion and the second side portion are positioned on the bottom surface side of the thickness center. This allows improving the holding property of the buttocks and reducing the wobbling feeling.

[Problem] To provide a cushion pad that allows reducing the oppressive feeling in a thigh and the sinking of buttocks and improving the texture and the fit feeling. [Solution] In a portion positioned underneath a hip point of a seated person, an under-buttock portion is set to have a smaller force Sduring compression to 25% in a second portion including a seating surface than Sof the first portion positioned on a bottom surface side. The thigh supporting portion is set to have smaller Sof a portion including the seating surface than Sof the first portion.

[Problem] To provide a cushion pad that reduces the bottom-hitting feeling. [Solution] In a support portion, the ratio of the hardness of a bottom surface layer including the bottom surface to the hardness of a seating layer including the seating surface is set to 1.0 to 1.1. The hardness of the seating layer is set to be identical to the hardness of the bottom surface layer or slightly smaller than the hardness of the bottom surface layer.
