Abstract
A method of manufacturing a cushion material including steps of: a mixed fiber manufacturing process in which main fibers and a plurality of types of heat-fusible fibers, which are formed of main fibers and sheath portions and whose sheath portions have different melting points, are mixed so as to make mixed fibers; a supplying process in which the mixed fibers are spread at a substantially uniform density at an entire one forming mold of a plurality of forming molds; and a heating process in which the mixed fibers spread at the entire one forming mold are heated such that a heating temperature of portions of a cushion material which are to be formed hard differs from a heating temperature of portions of the cushion material which are to be formed soft so that a number of types of the heat-fusible fibers which melt at the portions of the cushion material which are to be formed hard is greater than a number of types of the heat-fusible fibers which melt at the portions of the cushion material which are to be formed soft.
