    Patent number: 7445686
    Abstract: A process for producing an upholstered article in a bladder mold. A cover sheet with adhesive is positioned over the opened bladder mold. A foam core is inserted into the bladder mold, carrying the cover sheet into engagement with the bladder. The bladder mold is then closed so that the bladder wraps the marginal portion of the cover sheet around the foam core. After the adhesive cures to bond the cover sheet to the foam core, the mold is opened; and the article is removed.
