A direction-lockable seat assembly for a motor vehicle includes an upright seat post that defines a pivot axis, a seat member mounted on top of the seat post such that the seat member is rotatable about the pivot axis, and a direction-locking device that includes a locking plate, a slide guide unit, and a locking pin. The locking plate has a plate body mounted on top of the seat post and formed with a plurality of angularly spaced apart locking grooves. The slide guide unit is mounted on the seat member, and is formed with a slide channel to be aligned with a selected locking groove. The locking pin is movably disposed in the slide channel, and is operable to extend into the selected locking groove so as to arrest rotation of the seat member.
