Abstract: A portable traveller headrest is provided. The portable traller headrest includes a bar that may be articulated so that it can be folded onto itself, the ends of said bar having transversal holes to fix the bar to a seat with a fixing mechanism that adapts to different thickness of a top edge of various seats and fixes the bar to a backrest of the seats by pressure and at a desired height chosen by the user. Headrest elements, which comprise thin plates made of a rigid material and have a cushioned cover, can be connected, disconnected and rotated in discrete positions relative to the bar . The fixing mechanism is hingedly mounted in holes located on the bar, thereby requiring little space for storing the assembly.
