How do you repair a recliner chair arm that is loose?

To repair a loose recliner chair arm, first identify the source of the looseness by checking the screws and bolts that attach the arm to the chair frame. Tighten any loose screws or bolts with the appropriate tools. If the arm is still wobbly, inspect the joints and consider applying wood glue or replacing damaged hardware. Finally, reassemble the arm and test its stability before use.
