5. Operating Instructions (Adjustments)
The Ergolux Executive Office Chair offers multiple adjustment features to customize your seating experience for optimal comfort and ergonomic support.
5.1. 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 and pull the lever up. Release the lever at the desired height to lock it in place.
5.2. Backrest Recline and Lock
The backrest can recline from 90° to 160°. Pull the adjustment lever (typically on the left side) outwards to allow the backrest to recline. Lean back to the desired angle and push the lever inwards to lock the recline position. The chair also features three set locking positions and a free-swinging mode with tension adjustment.
5.3. Armrest Adjustment
The armrests are 3D adjustable. This means they can be adjusted for height, pivot (inward/outward), and depth (forward/backward). Locate the buttons or levers on the armrests to make these adjustments. Press the button or lift the lever, move the armrest to the desired position, and release to lock.

5.5. Lumbar Support Adjustment
The chair features flexible lumbar support designed to conform to your back. While specific manual adjustment mechanisms are not detailed, the design provides adaptive support. Some models may include a knob or lever for fine-tuning lumbar depth; consult your specific chair's physical controls.

6. Maintenance
Proper care and maintenance will extend the life and appearance of your Ergolux Executive Office Chair.
- Cleaning: For the genuine leather surfaces, wipe with a soft, damp cloth. Avoid harsh chemicals or abrasive cleaners. For deeper cleaning, use a specialized leather cleaner or conditioner.
- Leather Care: Apply a leather conditioner periodically to keep the leather supple and prevent cracking.
- Sunlight Exposure: Avoid prolonged direct sunlight exposure, as this can cause the leather to fade or dry out.
- Hardware Check: Periodically check all screws and bolts for tightness. Retighten as needed to maintain stability and safety.
- Caster Cleaning: Remove any hair or debris that may accumulate around the casters to ensure smooth movement.
