Abstract: A portable headrest which includes two padded tubular segments connected by a flexible web is described. Each tubular segment has a free end portion that includes fasteners to permit the user to connect these free end portions adjustably and detachably to each other. The headrest may be made from one piece of fabric sewn to create a tubular structure having five compartments. The innermost compartment is the web. The two compartments immediately adjacent the web are the padded tubular segments. The two outermost compartments are the free end portions. Once the free end portions are connected, the user places the headrest such that the tubular segments are positioned adjacent opposing lateral sides of the back of his head. The headrest thus supports the user's head against uncomfortable rotation and tilting so that the user can sit and/or sleep while sitting more comfortably without straining his neck.
