A headrest for a seat may have a headrest body, a support element having a rod end, and a base support element. The base support element is connected to the headrest body and the height can be adjusted relative to the support element using same. The headrest may also have a locking element for locking the base support element in an adjusted height position on the support element. The locking element may have a locking region and an actuation region. The locking region extends perpendicular to a transverse extension direction of the base support element and may be detachably blocked in a locked position. The actuation region extends from the base support element in a vertical direction. By actuating the actuation region, the locking region can be moved away from the bearing opening. A seat having a headrest of this type is also provided.
