A headrest for seats with a back has a top supporting body (1) arranged in the extension of the seat back (3) above the top edge (2) of the seat back (3) at the height of the head with a longitudinal axis (6) that extends in the horizontal direction parallel to the longitudinal axis (7) of the seat back (3). The lower side of the top supporting body (1) is in contact with or spaced from the top edge (2) of the seat back (3). At least two members (5) for laterally supporting the head are mutually spaced in the horizontal direction on the front side (9) of the top supporting body (1) and/or are integrated therein. At the level of the cervical lordosis of a seated person, a lower, substantially cylindrical supporting body (4) is arranged for supporting the cervical vertebral column. Seen from the side, the lower supporting body (4) has a substantially round, oval, elongated or semicircular cross-section, and its longitudinal axis (13) extends in the horizontal direction parallel to the longitudinal axis (6) of the top supporting body (1).
