Here is a detailed explanation:

1. Model Matching Issues

The '4009' queried by users differs numerically from the publicly disclosed Deli office chair models (such as the 4900 series). This discrepancy may be due to different model naming conventions or product iterations and updates. It is recommended to prioritize checking the complete model number on the product packaging, instruction manual, or purchase receipt to avoid affecting search results due to numerical input errors (such as '4009' versus '4900').

2. Function Reference for the 4900 Series
