Office Chair Locking Mechanism

The unlocking method for an office chair's locking mechanism depends on its adjustment type. Common types and operations are as follows:

1. Cable-Controlled Office Chairs
   These chairs typically use buttons to control locking and unlocking. To unlock, locate the button beneath the seat or on the side, press it gently, and lean back slightly until you hear a 'click' indicating successful unlocking. To relock, adjust the backrest to the desired angle and repeat the operation.

2. Knob-Adjusted Office Chairs

   • Knob at the Seat-Leg Connection: This knob, usually round and located beneath the chair, controls the recline function. To unlock, turn the knob counterclockwise to reduce resistance; to lock, turn it clockwise until resistance increases and the recline function is locked.
   • Knob at the Back of the Seat: Some chairs have the recline lock designed at the back of the seat. Turn the knob counterclockwise to unlock and clockwise to lock.

3. Lever-Adjusted Office Chairs

   • Side or Bottom Lever: These chairs are equipped with a lever that moves up and down or forward and backward. If the backrest is locked, locate the lever and lift it up or push it forward (direction varies by design) to restore the recline function; to relock, press the lever back into place.
   • Up-Down Toggle Lever beneath the Seat: Some chairs have a recline lock designed as an up-down toggle lever beneath the seat. Pulling it down locks the recline, and pushing it up unlocks it.

4. High-End or Special Design Office Chairs

   • Buttons/Knobs on the Armrest Side: Some high-end chairs integrate the recline lock on the side of the armrest, controlling the locking state by pressing buttons or turning knobs. When operating, observe if there are any markings on the armrest area and follow the indicated directions.

Precautions:

• Confirm the chair type before operating to avoid accidental damage.
• If the knob or lever has excessive resistance, gently shake the backrest to assist adjustment; do not force it.
• Some chairs require both 'adjusting the angle' and 'operating the control' to lock, such as cable-controlled chairs that need to be leaned back to the target angle before pressing the button.

If the chair still cannot be unlocked using the above methods, it is recommended to consult the product manual or contact after-sales service for repair to avoid damaging the chair structure due to improper operation.
