Abstract
In an orthopedic pillow in accordance with the present invention comprises a unitary body of foam or other resilient material with a deep generally hemispherical depression or aperture. The aperture receives the back of a user's head in such a manner that a portion of the weight of the head is supported directly by a mattress or the like beneath the pillow while the rest of the weight of the user's head is supported by the surrounding portion of the pillow. This design allows the user's head to rest generally on the same horizontal surface on which the remainder of the user's body rests. As a result, the head can shift backwardly into an ideal postural position in relation to the long axis of the user's body. In addition to holding the head, the pillow cushions the head by distributing its weight over a wide area. Also, the aperture is eccentrically positioned in the body to provide different distances between the edge of the body and the aperture. By orienting the pillow appropriately, it can be positioned to fit users with different neck lengths. Also, in one form of the invention, the size of the aperture is adjustable to fit various sized heads.
