4. Operating Instructions
The amseatec Ergonomic Mesh Office Chair offers several adjustable features to customize your seating experience:
- Height Adjustment: Use the lever located under the seat on the right side to adjust the chair's height. Pull the lever up while seated to lower, or pull up while standing to raise. Release the lever to lock the height.
- Rocking Tilt & Tension Control: The chair features a 90–110° rocking tilt. To enable rocking, pull the lever out. Push it in to lock the backrest in an upright position. The tension of the rocking mechanism can be adjusted by turning the round knob located under the seat. Turn clockwise for more resistance, counter-clockwise for less.
- Flip-Up Armrests: The armrests can be flipped up by rotating them upwards, allowing the chair to be pushed further under a desk or to provide more space when not needed. Flip them down for arm support.
- 360° Swivel: The chair base allows for smooth 360° rotation, providing easy access to different areas of your workspace without needing to move the entire chair.
