5. Operating Instructions
Your YIQIEDEY office chair offers several adjustable features to customize your seating experience:
- Height Adjustment: To raise the seat, lift the lever located under the right side of the seat while taking your weight off the chair. To lower the seat, lift the lever while remaining seated. Release the lever at the desired height.
- Tilt Function: Pull out the lever (often the same lever used for height adjustment) to enable the rocking mode. Push the lever in to lock the backrest in an upright position.
- Tilt Tension Control: The round knob located under the front-center of the seat allows you to adjust the tension of the tilt mechanism. Turn clockwise to increase tension (making it harder to recline) or counter-clockwise to decrease tension (making it easier to recline).
- Swivel: The chair features a 360-degree swivel function, allowing for easy rotation without moving the base.

- Wipe plastic and metal parts with a damp cloth.
- Inspection: Periodically check all screws and bolts to ensure they are tight. Re-tighten if necessary.
