Abstract
On an article of furniture, a bearing assembly is disposed between an elongate central structure and a seat, which permits rotation between the seat and the base. A tablet is provided, which is connected to a tablet arm with a first cylindrical member, and the tablet arm is connected to the elongate central structure of the base with a second cylindrical member. The second cylindrical member is disposed around the elongate central structure with a flange at the upper end thereof. The bottom of the seat has a lobed friction bushing disposed such that the flange of the second cylindrical member contacts the lobed friction bushing and frictionally resists rotation of the tablet arm as the seat rotates 360 degrees relative to the base, leading the tablet to follow the seat as it rotates. A lobed friction bushing is also provided.
