A leg assembly includes at least three upright support members and at least three horizontal link members. Each of the support members includes an adjacent pair of planar first and second leg frames that are connected pivotally to each other, and at least one connecting plate disposed between the first and second leg frames so as to form an angle between the first and second leg frames such that the first and second leg frames can stand stably on a ground surface. Each of the link members is connected detachably to an adjacent pair of the support members so as to interconnect and position the support members relative to one another.
