A method for making a support pad of synthetic foam having a three-dimensionally shaped support surface characterized by raised portions separated by depressions. The method comprises the steps of providing a slab of synthetic foam having a planar surface and providing a die having raised portions separated by depressions. The planar surface is pressed against the die surface with sufficient force to extrude portions of the slab into the depressions of the die. The extruded portions are cut away from the slab. Apparatus for carrying out the method is also provided.
