Abstract: [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.

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.
