Abstract
Abstract A composite pillow of the type including one or more elements for receiving the neck or cervical region of a person lying on the pillow and another, adjacent element for receiving the person's head or occipital region, the purpose being to support the neck and head in the position occupied when the person is errect. The neck-receiving is of greater firmness than the adjoining element. In this invention, the neck-receiving element is made up of at least two end-to-end sections, one of firmness as aforesaid and the other containing a compartment enclosing an air bag which is selectively inflatable to vary the firmness of that section relative to the remainder of the pillow, thus enabling the pillow to contribute, for example, to the solution or at least alleviation of several temporary posture abnormalities suffered by the using person. In a modified form, the adjacent element of the pillow also has an air bladder therewithin which may be selectively inflated to further contribute to the ultimate comfort and/or cure of the user.
