2. Operating Your Chair
The Newtral Ergonomic Office Chair offers a range of adjustments to customize your seating experience for optimal comfort and ergonomic support.
2.1. Auto-Following Lumbar Support
The unique auto-following backrest mechanism provides continuous support to your spine, adapting to your posture whether you are leaning forward or backward. This feature is designed to reduce back pain and promote a neutral spinal alignment.

2.2. Headrest Adjustment
The headrest can be adjusted in 2 dimensions (2D) to provide optimal neck and head support. Adjust its height and angle to suit your preference and maintain proper cervical spine alignment.
2.3. 3D Armrest Adjustment
The armrests offer 3-dimensional adjustments for personalized comfort and support. You can adjust them:
- Up and Down: Adjust the height to align with your desk and support your elbows.
- Forward and Backward: Slide the armrest pads to find the ideal position for typing or relaxing.
- Left and Right (Pivot): Rotate the armrest pads for ergonomic support during various tasks.

2.4. Seat Depth & Height Adjustment
Adjust the seat height to ensure your feet are flat on the floor and your knees are at a 90-degree angle. The seat depth can also be adjusted to provide proper thigh support, leaving a small gap between the edge of the seat and the back of your knees.
2.5. Backrest Tilt and Recline Tension
The backrest offers multiple tilt angles (96°, 116°, 126°) to support various activities from formal work to relaxed reclining. The recline tension can be adjusted to match your body weight and preference, allowing for smooth and controlled tilting.

3. Maintenance
Regular maintenance will help prolong the life and performance of your Newtral Ergonomic Office Chair.
- Cleaning: Wipe down plastic and metal parts with a soft, damp cloth. For the mesh backrest and fabric seat, use a mild soap solution and a soft brush, then wipe dry. Avoid harsh chemicals or abrasive cleaners. The seat cushion is designed with water-resistant properties for easier cleaning.
- Inspections: Periodically check all screws and bolts to ensure they are tight. Re-tighten any loose fasteners to maintain stability and safety.
- Casters: Clean casters regularly to remove dust, hair, and debris that can impede smooth movement.

4. Troubleshooting
If you encounter any issues with your Newtral Ergonomic Office Chair, please refer to the following common solutions:
- Chair Squeaks: Check all bolted connections and tighten them. A small amount of silicone spray on moving metal parts (avoiding the gas lift cylinder) can also help.
- Difficulty Adjusting Height: Ensure no weight is on the chair when attempting to raise it. If lowering, apply slight pressure while operating the lever. Check if the gas lift is fully inserted into the base.
- Wobbly Chair: Verify that all screws are securely tightened, especially those connecting the seat to the mechanism and the backrest. Ensure the casters are fully inserted into the base.
- Laptop Table Tray Not Stable: Ensure the tray is correctly attached to the armrest and all locking mechanisms are engaged.
If problems persist after attempting these solutions, please contact customer support.
