Operating Instructions
Your YFO ZBWY002 office chair offers several adjustable features to enhance your comfort and support:
- Height Adjustment: Use the lever located under the seat on the right side to raise or lower the chair to your desired height.
- Lumbar Support Adjustment: The lumbar support can be adjusted vertically to align with the natural curve of your spine. Gently push or pull the lumbar pad to reposition it.
- Armrest Adjustment: The 4D armrests can be adjusted for height, forward/backward position, and rotation. Use the buttons or levers on the armrests to make these adjustments.
- Tilt and Rocking Function: The tilt tension knob underneath the seat controls the resistance of the backrest when reclining.
