ABSTRACT:
The invention comprises a therapeutic pillow (10) for supporting the head and neck of a person lying in a supine position. The pillow (10) comprises a pair of pillow members (11) and (12) combined to form a single pillow. Pillow member (11) has upper opposite sides (16) and (21) joined to the upper portions of opposed edges (17) and (19), one of which is higher or thicker than the other, a planar surface (18) joining the lower portions of the edges (17) and (19), and a normally non-exposed irregular surface (23-28) extended between the sides (16) and (21). The second pillow (12) has one side (32-37) that mates with the irregular surface of the first pillow member (11) and an opposite side (31) which is relatively smooth. The density of the two pillow members varies, member (11) being more dense than member (12).
