Abstract
A pillow core (1) is made from a foamed plastics material which is softly resilient, and has its upper thickness formed with upright parallel ribs (5) spaced from one another by slots of elongated cross-section. The ribs have their upper surfaces attached to the underside of a porous web (3) which is soft and flexible but relatively inextensible in its own plane. The lower thickness of the core (1) is formed with cylindrical sockets (11) containing removable plugs (14) of foamed plastics material removable from their sockets through respective slits (12) formed in the underside of the core. The upper thickness of the core gives the pillow surface a soft plush feel, and the plugs are selectively removable to alter the resistance to compression of the pillow.
