Abstract: A drive device for a movable furniture part including a support to be fastened to a furniture carcass, an actuation arm device mounted movably on the support and to be connected to the movable furniture part, an energy store for applying force to the actuation arm device, a damping device for damping a closing and opening movement of the actuation arm device, and an adjusting device for adjusting a force of the damping device, a damping start position in relation to an angle position of the actuation arm device, and/or in terms of a damping travel. The adjusting device includes an adjusting element coupled to the damping device such that an adjustment of the damping force, damping start position, and/or damping travel takes effect when the actuation arm device is damped during the closing movement, and when the actuation arm device is damped during the opening movement.
