Maintenance

To maintain the condition and functionality of your Marsail office chair, follow these simple maintenance tips:

• Cleaning: Wipe clean with a damp cloth. Avoid harsh chemicals or abrasive cleaners.
• Regular Checks: Periodically check all bolts and screws to ensure they are tight. Retighten if necessary.
• Caster Care: Keep the caster wheels free of hair and debris to ensure smooth movement.
• Fabric Care: For mesh and fabric areas, use a soft brush or vacuum cleaner to remove dust and dirt.
