Abstract
A composite plastic foam pillow has a convoluted upper surface, a flat lower surface and a core disposed between those surfaces which is provided with a central void for imparting decreased firmness to the pillow adjacent the void. It is fabricated by coring a block of plastic foam, cutting out a central portion of the core, and then replacing the core and sealing it in its original position.
