A method and an apparatus for the moulding of an inhomogeneous product, such as an ergonomically shaped car seat pad, from a raw material mass in a gas-pervious mould (10). The mould includes two main parts moving towards each other (12, 14) and is fitted in a gas flow in such a way that the hot gasflow (30) flows through the mould (10) and through the raw material mass (28). In the mould it is composed before the cooling of the product at least two different zones (24, 26, 44, 46, 48, 50). In the first zone (26, 44, 48) it is composed a raw material mixture of greater density than in the second zone (24, 46, 50), either by pressing the opposite parts of the mould (12, 14, 16, 18, 20, 38) towards each other at a longer distance at the point of the first zone than at the point of the second zone; or so that the first zone (48) of the mould is filled with a more dense raw material mixture than the second zone (50), by arranging a bigger flow-through of the gas-flow carrying the raw material mass through the openings (52) in the mould parts (54) confining the first zone than through the openings in mould parts confining the second zone.
