An office chair base is the bottom part of every office chair securing its vertical stability and providing free movement in a horizontal plane perpendicular to the axis of the vertical support column. The movement in all existing office chair bases is effectuated by means of using casters. In this invention the casters are eliminated and replaced by new movement mechanisms consisting of radial ball bearing in a horizontal plane and injection molded plastic ball, eccentrically mounted to it. The mechanisms will not be visible to the user and will be located in sockets on the side facing the floor.
