Abstract
A cushion for supporting the head of a user reposing in a sitting or semi-reclining position comprises a relatively stiff body constituting a segment of a torus. The length and curvature of the body are such that when the body is positioned on the user's shoulder at one side of the midsagittal plane, the body extends from a location adjacent to the mastoid process behind the user's ear forwardly to a point beyond the midsagittal plane to the mental terminus of the user's mandible so that said body provides positive anatomically correct support for the user's head no matter which direction the head nods or tilts to said one side of the midsagittal plane. A novel method of making the cushion is also disclosed.
