Abstract: A vertical tubular frame rigidly but detachably secured to the front wall of a bar at a right angle with said bar and extending out from under said bar at a suitable level to provide an arm rest for the occupant of a castersupported bar stool pivotally connected to the front vertical element of said frame on the axis of said element, with the back of said stool, when the latter is facing said bar, approximately parallel with and equidistant from the bar with said axis.The stool is swingable solely about said axis between an inner position, where it thus faces said bar and an outer position where it faces at approximately a right angle to the bar, thereby facilitating a person entering or leaving the space between the bar and said stool. The radii on which the casters turn intersect said vertical axis of said front frame element so as to track with said stool when the latter is swung about said element. Said casters are also adjustable vertically to assure smooth operation of the stool.
