Operating Instructions
Your DEVAISE ABGY013 chair offers multiple adjustment features for personalized comfort.
1. Seat Height Adjustment
To adjust the seat height, locate the lever on the right side beneath the seat. While seated, pull the lever up to lower the seat. To raise the seat, stand up slightly and pull the lever up. Release the lever at the desired height.
2. Backrest Recline and Lock
The backrest can recline from 90° to 135°. To recline, pull the lever on the left side beneath the seat. Lean back to your desired angle and release the lever to lock it in place. To return to an upright position, pull the lever again and lean forward slightly.

3. Tilt Tension Adjustment
The tilt tension knob is located underneath the front of the seat. Turn the knob clockwise to increase the tension, making it harder to recline. Turn it counter-clockwise to decrease tension, allowing for easier recline.
4. 3D Adjustable Armrests
The armrests offer three-dimensional adjustments:
- Height Adjustment: Press the button on the side of each armrest and move it up or down to your preferred height. Release the button to lock.
- Forward/Backward Adjustment: Slide the armrest pad forward or backward.
- Rotation: Rotate the armrest pad left or right.

- Height Adjustment: Pull the headrest up or push it down to adjust its vertical position.
- Angle Adjustment: Tilt the headrest forward or backward to find the most comfortable angle.
