PROBLEM TO BE SOLVED: To provide a cushion pad capable of suppressing wobble feeling.SOLUTION: A test piece collected from a core part has flexure equal to or less than 30 mm to a load 100 N during compression which is measured in compliance to an E method regulated by JISK 6400-2 (Fiscal 2012), and a static spring constant equal to or less than 25 N/mm during 300 N compression measured by tension speed of 20 mm/minute. When there is vibration input of a low frequency band in a lateral direction, compression stress in a vertical direction by weight of a seating person, and tension stress by vibration input in a lateral direction act on a support part 2. Since a direction (inclination) of resultant of the compression stress and tension stress can be approached to the vertical direction, so that an angle of inclination of a hip of the seating person by the vibration input can be reduced, and thereby wobble feeling can be suppressed.SELECTED DRAWING: Figure 2 |
