ABSTRACT:
A chair armrest bar is horizontally slidably received in a channel of a base attached to a chair seat. The base defines longitudinally arranged interconnected slots in its bottom wall. A locking lever is pivotably mounted to the armrest bar. The lever has a locking pin which is biased into one of the slots to lock the armrest in position; the lever may be tilted to an unlocking position to allow the bar to slide. The lever is releasably attached to the bar by a mount so that the lever may be removed to allow replacement of the bar.
