Maintenance
Proper care will extend the life and appearance of your gaming chair.
- Cleaning: Wipe clean with a damp cloth. For tougher stains on the fabric, use a mild fabric cleaner and test on an inconspicuous area first. Avoid harsh chemicals or abrasive cleaners.

- Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause fabric fading.
- Weight Limit: Adhere to the maximum weight recommendation of 220 lbs to prevent structural damage.
