• Flip-up Armrests: The armrests can be flipped up 90° to allow the chair to be stored under a desk, saving space. Simply lift or lower them as needed.

• Casters: Periodically check casters for hair or debris that may hinder smooth rolling. Clean as needed.
• Hardware: Occasionally check all screws and bolts to ensure they remain tight. Retighten if necessary.
