Office Chair Not Reclining

The inability of an office chair to recline may be due to incorrect operation or improper settings of the adjustment mechanism. This can be resolved by checking the adjustment components, adjusting the tension, or unlocking the locking function. Below are the specific causes and corresponding solutions:

1. Adjustment Lever/Knob Not Activated
   Most office chairs require activation of the side handle, knob, or bottom lever to enable the recline function. If the adjustment components are not operated, the backrest will remain locked.

   • Lever-Type: Locate the lever beneath the seat (some chairs may require stepping on or pulling up). While seated, gently lean back and adjust to the desired angle, then release the lever to lock.
   • Knob-Type: Find the knob on the side or beneath the seat (usually on the right). Rotate the knob (clockwise typically increases resistance, counterclockwise decreases it) to adjust the recline angle.

2. Tilt Lock Function Enabled
   Some chairs are equipped with a 'Lock Tilt Angle' button (usually near the adjustment lever). If enabled, the backrest will not recline.

   • Look for a button or toggle labeled 'Lock' near the adjustment lever and switch it to the 'Unlock' position.

3. Excessive Tension Setting
   Chairs with tension adjustment (controlled by a knob or dial) may have too much resistance, making it difficult for lighter individuals to recline.

   • Locate the tension adjustment knob beneath the seat (usually near the center close to the支柱/support column). Rotate counterclockwise to reduce resistance, lowering the force needed to recline the backrest; rotate clockwise to increase resistance, suitable for heavier individuals or those needing a fixed angle.

4. Component Sticking
   Accumulated dust or insufficient lubrication in the adjustment lever spring or pivot points may cause mechanical sticking, affecting the recline function.

   • Regularly clean the adjustment components (e.g., use a soft brush to remove dust) and apply a small amount of lubricant (such as WD-40) to the pivot points. After application, rock the chair back and forth multiple times to distribute the lubricant.

If none of the above methods work, there may be damage to the internal mechanical structure (such as a broken spring or faulty gas lift). It is recommended to contact a professional repair technician for inspection or replacement of parts. Avoid forceful operation of the adjustment components during daily use to extend the chair's lifespan.
