5. Operating Instructions

Your Newtral Ergonomic Office Chair offers multiple adjustment features to customize your seating experience.

5.1. Lumbar Support Adjustment

The chair features revolutionary auto-following lumbar tracking technology. This system dynamically adjusts to your spine's movement, providing continuous and personalized support. No manual adjustment is typically needed for the auto-following function, but you can adjust the intensity of the lumbar support using the knob on the side of the backrest.

5.2. 4D Armrest Adjustment

The armrests are 4-dimensional, allowing for precise positioning to support your arms and shoulders. Adjustments include:

• Height: Move armrests up or down.
• Depth: Slide armrests forward or backward.
• Width: Move armrests inward or outward.
• Pivot: Rotate armrest pads left or right.

5.3. Seat Height and Depth Adjustment

Use the levers located under the seat to adjust the seat height and depth. This allows you to find the optimal position for your legs and thighs, promoting better circulation and reducing fatigue.

5.4. Reclining Function

The chair offers multiple reclining positions (96°, 120°, 136°) and adjustable tilt strength. Use the recline lever and tension knob under the seat to find your preferred angle and resistance for relaxation or focused work.

5.5. Headrest Adjustment

The headrest is adjustable to provide multi-angle support for your neck. Move it up or down and tilt it to achieve optimal neck and head alignment.

6. Maintenance

To ensure the longevity and performance of your Newtral Ergonomic Office Chair, follow these care instructions:

• Cleaning: The manufacturer recommends dry cleaning for the fabric components. For mesh and plastic parts, wipe with a damp cloth and mild soap, then dry thoroughly. Avoid harsh chemicals or abrasive cleaners.
• Inspection: Periodically check all screws and connections to ensure they remain tight. Re-tighten if necessary.
• Moving the Chair: When moving the chair, lift it rather than dragging it to prevent damage to the base and floor.
