Abstract
Abstract A composite pillow made up of a sheet of foamed material shaped into sleeve-like form with limited-area portions contacting and adhered to each other to give the pillow a shape somewhat of a pear lying on its side; i.e., with the lengthwise axis of the pear being horizontal. The sleeve-like sheet provides a peripheral wall within which a fairly large cavity exists to one side of the junction between the joined areas, and this cavity contains an air bag or the like which may be selectively inflated to provide support for the user's neck while the user's head rests on the small part of the "pear".
