Abstract
A method of making an upholstered element wherein a cover is introduced into a mold to which it tightly adheres. The mold is closed by means of a first lid, following which a soft-foam reaction mixture is introduced into a first hollow chamber of the mold closed off by the first lid. At the end of the reaction, the soft-foam reaction mixture fills the first hollow chamber and forms a soft-foam body. Subsequently, the first lid is removed from the mold and replaced by a second lid, the soft-foam body remaining in the mold. Between the soft-foam body in the mold and the second lid, a second hollow space is formed. Subsequently, a rigid-foam reaction mixture is introduced into the second hollow chamber, which at the end of the reaction fills the second hollow chamber and forms a rigid-foam body.
