Troubleshooting

If you encounter any issues with your FelixKing Office Chair FK918-H, refer to the following common troubleshooting tips:

• Backrest Recline Issues: Check the tension device under the seat. Adjust it to increase or decrease recline resistance. Ensure no obstructions are preventing the backrest from moving freely.
