A seat adjustment first lever is adapted to be mounted to a first lateral end of a recline mechanism of a seatback. Rotation of the first lever about a pivot axis disengages the recline mechanism. The first lever includes a first lever input portion extending from the pivot axis for manual rotation of the first lever. A second lever input portion extends from the pivot axis and is sized to receive an input cable for actuation of the first lever from a remote location. A lever output portion extends from the pivot axis and is sized to receive an output cable to connect the first lever to a second lever on a second lateral end of the recline mechanism.
