The middle leg tube includes at least one hole. The lower leg tube includes at least one opening. The rotary member is assembled with the seat base and affixed to the upper leg tube. The first latch is disposed on a bottom of the upper leg tube and adapted to detachably engage with the at least one hole for constraining a movement between the upper leg tube and the middle leg tube. The second latch is disposed on a bottom of the middle leg tube, and adapted to detachably engage with the at least one opening for constraining a movement between the middle leg tube and the lower leg tube.
