Abstract
[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. This allows reducing the increase in reactive force by the bottom surface layer while supporting the load of the seated person by the bottom surface layer. This allows reducing the bottom-hitting feeling.
