Foamed seat cushions are manufactured in a female mould (10) by using vacuum applied through a series of holes (20) in the mould wall to draw a fabric seat covering layer (22) into contact with the mould inner wall and then introducing a foam (26) which fills the internal space in the mould. Subsequent to the curing of the foam in the mould, a positive pressure is applied through the same holes in the mould wall, before the mould is opened, to crush the foam resulting in the resilience of the foam being adjusted to the desired level. |
