Abstract
A rocking chair has an aluminum frame chair portion that is mounted to a base by a pair of coil springs that provide rocking action to the chair. The springs are fixedly attached to the base and each spring has an outwardly extending portion that is attached to the seat portion by extending into a passage of the chair portion. The outwardly extending portion has a notch, and a set screw extends into the passage engaging the notch to retain the portion within the passage, preventing the possibility of the chair portion becoming separated from the base.
