If you encounter any issues, refer to the following common solutions:

• Chair Wobbles: Check and tighten all screws, especially those connecting the armrests and the base. Ensure the gas lift is properly seated in the base.
• Difficulty Adjusting Height: Ensure the gas lift lever is fully engaged. If the issue persists, the gas lift cylinder may need replacement.
