4. Operating Instructions
4.1. Adjustable Armrests
The armrests can be adjusted for height and can be flipped up 90 degrees for space-saving storage.
- Height Adjustment: Locate the button or lever on the side of the armrest. Press it and slide the armrest up or down to your desired height. Release the button/lever to lock.
- Flip-Up Function: To fold the armrests up, lift them upwards until they lock into a vertical position. To return them to the down position, gently pull them down. This allows the chair to be stored under most desks, maximizing room space.

4.2. Seat Height Adjustment
To adjust the seat height, locate the lever on the right side beneath the seat.
- To Raise: While seated, lift the lever and slightly lift your weight off the seat. The seat will rise. Release the lever at the desired height.
- To Lower: While seated, lift the lever and apply your weight to the seat. The seat will lower. Release the lever at the desired height.
4.3. Tilt Function and Tension Control
The chair features a tilt mechanism allowing the backrest to recline, and a tension knob to control the resistance.
- To Recline: Pull the lever on the left side beneath the seat outwards. Lean back to recline. Push the lever inwards to lock the chair in an upright position.
- Tilt Tension Adjustment: Rotate the round knob located under the front of the seat. Turn clockwise to increase tilt tension (more resistance) or counter-clockwise to decrease tension (less resistance).
4.4. Swivel and Mobility
The chair is designed for smooth 360-degree swivel and effortless movement.
- Swivel: The chair seat can rotate 360 degrees freely.
- Mobility: The high-quality, silent-rolling casters allow for easy movement across various floor surfaces, including carpet and hard-wood floors.
