Cushion body

Abstract

A cushion body includes a main body made of elastic foam and having at opposite sides thereof first and second surfaces between which a thickness is defined, the main body being formed with a plurality of holes in a direction of the thickness, a plurality of columnar elastic members positioned in the plural holes, respectively, the plural columnar elastic members being different from the main body in elasticity, a first surface member made of elastic foam similar to the elastic foam of the main body, the first surface member being connected to the first surface of the main body, and a second surface member made of elastic foam similar to the elastic foam of the main body, the second surface member being connected to the second surface of the main body.
