Abstract
A seat (1), in particular for vehicles, with foamed plastic padding (4, 5), has a supporting body (7) made of an open-cell elastic foamed plastic having a first specific gravity. A flame-retardant layer (12) made of an open-cell elastic foamed plastic having a second specific gravity different from the first and/or an upholstery material (14) is provided. An intermediate layer (9) is arranged between the supporting body (7) and the flame-retardant layer (12) and/or the upholstery material (14). The intermediate layer is non-flamable, and composed of a lattice or mesh of high temperature resistant fiber or threads, and/or liquid repellent. The supporting body (7) can be foamed on to the intermediate layer (9). A process for manufacturing the seat (1) is also described.
