A method of manufacturing a seat pad having a cover of two, or more, materials. The method comprises the steps of cutting blanks (26, 28) of the different materials and securing the blanks to one another by welding each pair of blanks to a joining strip (20) formed with one or more locating formations (25, 27). The joining strips (20) are positively located in a mould cavity or a preformer by mating engagement between the mould cavity or preformer and the locating formations (25, 27) of the joining strip(s) (20). The material is then stretched to conform to the shape of the mould cavity and a plastics foam is cast into the stretched material. |
