A seat assembly includes a seat and armrests that are movable relative to the seat. An armrest lock supports each armrest for movement relative to the seat between a raised storage position and a lowered armrest position. Each armrest lock is movable relative to the seat between an armrest-locking position and an armrest-releasing position. Each armrest lock is able to move to its armrest-locking position once its companion armrest has been moved to assume either the raised storage position or the lowered armrest position.
