表皮が形成されている。Conventionally, urethane foam cushioning materials with excellent handling and durability have been widely used as cushioning materials for seat cushions and backrests in place of natural fibers or metal springs. A so-called molded cushion is used that is molded to match the shape of the seat cushion or backrest.This molded cushion is made by foaming urethane resin or the like in a predetermined mold to create a large number of open cells. It is formed into a sponge-like shape, and a non-breathable epidermis called a skin layer is formed on the entire outer surface.

うような欠点があった。(Problems to be Solved by the Invention) However, in this molded cushion, an epidermis called a skin layer is formed on the entire outer surface during molding, and this epidermis has no air permeability, so the air permeability inside the cushion is limited. Not only is this extremely inhibited, making it uncomfortable to sit on, but when a user sits on the cushion, the inside of the cushion becomes stuffy due to the user's body temperature, and the urethane foam itself is susceptible to high temperatures and humidity, reducing the lifespan of the cushion material. The disadvantage was that it shortened the .
