Cushioning devices
First Claim
1. A cushioning device made of a resilient foamed plastic material, the cushioning device having a lower thickness and an upper thickness, the upper thickness being covered by a continuous, soft, thin, flexible layer, and there being parallel slots in the upper thickness, whereby the upper thickness is divided into ribs, and in which said layer is made of a material that is different from that of said ribs, is cemented to said ribs;
- and is resilient in its own plane.

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.

14. A cushioning device made of a resilient foamed plastic material, the cushioning device having a lower thickness and an upper thickness, the upper thickness being covered by a continuous, soft, thin, flexible layer that is made of the same material as the upper thickness and is integral therewith, and there being parallel slots in the upper thickness, whereby the upper thickness is divided into ribs.
