<human>:  How do I fix a wobbly chair leg?
<bot>: First, you will need to identify the source of the wobble. If the leg is loose from the frame, use a screwdriver to tighten the connection at the joint. If the frame is the problem, you may need to insert shims to support the leg and make it secure. Use furniture glue and a clamp to hold the shims in place until the glue is dry. Finally, if the chair leg has been damaged structurally, replacing it may be necessary.
