As described above, the present invention rotatably connects the elbow rest to the rotating member, and also rotatably connects the rotating member to the support, so that the elbow rest is in a horizontal state when engaged with the support, and When it is disengaged from the support and rotated upward, it locks in the vertical position, and when it rotates further downward, it locks in that position, so the elbow rest can be attached depending on whether or not an elbow rest is required. It is extremely easy to create a state without arm rests, and when there are no arm rests, the arm rests hang down below the sides of the chair, so their presence does not get in the way at all, while with arm rests Since the distance between the left and right elbow pads can be adjusted steplessly, it can be used in the best condition that suits the user's physique, and can be used with or without elbow pads. It is easy to use and can not only reduce fatigue caused by VDT work, but also achieve the same effect when used as a general office chair.
