The invention relates to an upholstered part of a vehicle seat (100), at least including a foam part (12-2) which, in a foaming process, forms a permanent connection to a prefabricated shaped nonwoven (12-1), wherein the prefabricated shaped nonwoven (12-1) forms a supporting structure for the foam part (12-2). It is provided that the prefabricated shaped nonwoven (12-1′) has at least one locally situated open cavity (12-11′) which at least in sections is filled with foam, so that the foam part (12-2′) has a foam-embedded supporting and reinforcing structure at least in one section (11B′) of the cavity (12-11′).
