ABSTRACT:
This invention relates to a contoured neck pillow. The invention consists of a central pad of polyurethane foam having a compression of about seven pounds, which is relatively softer and more elastic than a surrounding ring of polyurethane foam having a compression of about fifteen to twenty pounds. Two convoluted foam sections enclose the ring and pad, and are in turn encased within a protective cover.
