Abstract
Spring means integrated as a unit for ready association with the rocker and base elements of a chair by the attachment of the unit in situ for operational use, securement to the base and/or rocker elements being obtained without the use of screws or bolts by stops on the spring retainers comprising axially-aligned horizontally-disposed extensions which extend outwardly beyond the walls of an opening in the rocker base or rocking component through which the rocker spring unit passes thereby precluding unwanted displacement of the unit away from the rocker and base elements as the chair is rocked.
