Abstract
Abstract A pillow unit for the head of a person in a chair or in a vehicle seat is attached to the back of the seat and supports the head when the person is in a relaxed, sitting position. The pillow unit includes a pillow extending outwardly from the seat back a sufficient distance and at a proper angle to adequately support the head, and means for affixing the pillow to the seat at the level of the head and to one side of the center of the seat back. In a preferred form, the pillow is affixed to a base sheet which, in turn, is attached to the seat back by elastic straps or by means of Velcro, by way of example. Also in a preferred form, the pillow includes a cover and a removable pillow insert which can be removed for the purpose of cleaning the cover and the base sheet. If desired, two of the pillows can be employed with the base sheet spaced apart a distance sufficient to receive the person''s head to support either or both sides thereof.
