A swivel arm structure suitable for supporting a video display apparatus or the like and for positioning such apparatus with substantial discretion and ease. A first, horizontally movable arm is pivotally attached to a fixedly mounted base, which movable arm can be articulated at multiple movement interrelated joints within the horizontal plane. A vertically translating parallelogram type linkage is attached at one end to the horizontally articulatable arm and at the other end supports the apparatus. In one form one linkage member is situated within the tubelike structure of the other linkage member. The swivel arm can be freely moved, without angle induced binding of hinges, to position the apparatus.
