  • Publication number: 20190223633
    Abstract: The present invention relates to a composite travel pillow that fits about the neck of a wearer for support in a seated or semi-reclined position. Notably, the present pillow includes a resiliently deformable, relatively stiff cap portion fitted to a shoulder portion of the pillow, with the cap portion defining a pair of spaced apart reactive surfaces that can engage an associated seating area. During use, the reactive surfaces provide dynamic interaction with the seating area, with the cap portion mechanically flexing and shaping the pillow on the user. Greatly enhanced support of the head and neck of the user is achieved, considerably enhancing the comfort provided by the pillow when in used in a seated or semi-reclined position.
