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.
