Apparatus is disclosed for manufacturing a resilient cushion of foamed plastics material with an integrated cover cloth. The apparatus includes means for accepting a piece of cover cloth between frames to dispose the cloth across the mouth of a vacuum mould and control the peripheral contraction of the cloth as it is drawn into the mould by vacuum, prior to casting the foamable plastics mix into the mould. The apparatus limits the amount of peripheral contraction permitted in the cloth to avoid wrinkles or plaits in the surface of the finished cushion.
