Abstract A one-piece bed pillow consisting of a pillow shaped molded body of open cell urethane foam material having its outer surface formed with a regular pattern of interconnected grooves. The pillow is formed in a mold which is placed in an upright position during foaming of the pillow body so that in use the pillow has a plurality of internal cells which are generally perpendicular to the direction in which load is applied to the pillow to thereby impart desirable load-deflection characteristics to the pillow so that it has low resistance to initial load and has increased resistance to higher loads. The user of the pillow thus finds that it has a desirable initial softness with a subsequent firmness that gives the user confidence in the ability of the pillow to hold the user's head.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
125 words
A one-piece bed pillow comprising a pillow shaped molded body of open cell urethane foam material having a continuous outer surface, said body being adapted to be placed in a generally horizontal load supporting position in which it has a top load supporting surface, ends and sides, said outer surface being formed with a regular pattern of shallow surface depressions, substantially all of said depressions being interconnected to thereby impart surface softness to said body member, said body member having a plurality of internal interconnected elongated open cells extending in generally the same direction as said load supporting surface to thereby provide said body with desirable load-deflection characteristics wherein said pillow has a soft resistance to initial load and has increased resistance to larger loads.
Claim 2
Dependent Claim
125 words
A one-piece bed pillow comprising a pillow shaped molded body of open cell urethane foam material having a continuous outer surface, said body being adapted to be placed in a generally horizontal load supporting position in which it has a top load supporting surface, ends and sides, said outer surface being formed with a regular pattern of shallow surface depressions, substantially all of said depressions being interconnected to thereby impart surface softness to said body member, said body member having a plurality of internal interconnected elongated open cells extending in generally the same direction as said load supporting surface to thereby provide said body with desirable load-deflection characteristics wherein said pillow has a soft resistance to initial load and has increased resistance to larger loads.
Claim 3
Dependent Claim
46 words
A foam pillow according to claim 1 wherein said cells in said body are elongated in a direction extending from side to side thereof so that said cells extend in directions generally transversely of the direction of downwardly directed loads applied to said load supporting surface.
