Seat pad and seat pad manufacturing method

Abstract

A seat pad with improved thermal comfort and improved vibration absorptivity and a seat pad manufacturing method for easily obtaining the seat pad are provided. In the seat pad (1), when a surface portion (2) up to 10 mm from a surface (1f) is cut out and the air permeability AR1 of the surface portion (2) is measured in compliance with JIS K 6400, the air permeability AR1 is more than 5 cc/cm2/sec and 25 cc/cm2/sec or less. The seat pad manufacturing method is a seat pad manufacturing method for obtaining the seat pad (1) by supplying a molding material into a molding die and performing foam molding. As the molding die, a molding die an inner surface of which is covered with polystyrene or polyethylene is used.
