A method for forming seat cushions reduces the mold release time. A structure (2) is formed when three or four surfaces of four surfaces, excluding the two end surfaces in the extrusion direction thereof, cure. Normally, the density of the structure (2) is higher than other regions, and the structure (2) is provided with a total of six surfaces: a top surface, a bottom surface, a left surface and a right surface (see fig. 9 and 10), and two end surfaces that have been cut (see fig. 11). The structure (2) is formed according to a formation method comprising the following steps. (1) A compression step in which the structure (2) is compressed in a mold (3). (2) A thermal softening step in which the structure (2) is thermally softened by means of a heating medium. (3) A curing step in which the structure (2) directly undergoes forced cooling in a cooling medium, and is then cured. (4) A mold release step in which the structure (2) is released from the mold (3). |
