Operating Instructions and Adjustments
Your tectake Arges office chair offers several adjustment options to customize your seating experience for optimal comfort and ergonomic support.
Chair Height Adjustment
To adjust the seat height (approx. 45-55 cm):
- To raise: Lift the lever located under the seat on the right side while taking your weight off the seat. The seat will rise automatically.
- To lower: Lift the lever while seated. The seat will lower under your weight. Release the lever at the desired height.
Backrest Tilt Function
The chair features a tilt function with adjustable resistance.
- To activate/deactivate tilt: Pull out or push in the lever located under the seat (often the same lever as height adjustment, or a separate one).
- To adjust tilt resistance: Turn the round knob located under the front of the seat. Turn clockwise to increase resistance (making it harder to tilt) and counter-clockwise to decrease resistance (making it easier to tilt).
Adjustable Lumbar Support
The lumbar support is height-adjustable to provide targeted support for your lower back.
- Grasp the lumbar support pad on the backrest and slide it up or down to your preferred position.

The headrest can be adjusted in both height and angle.
- Height Adjustment: Gently pull the headrest up or push it down to adjust its height.
- Angle Adjustment: Tilt the headrest forward or backward to find the most comfortable angle for your neck and head.

Reclinable Armrests
The armrests can be tilted backward to allow the chair to be pushed closer to a desk or for easier movement.
- Simply lift the armrests upwards to recline them. Push them back down to their original position.
Maintenance and Care
Proper maintenance will extend the life of your tectake office chair.
- Cleaning: Clean the chair using a damp cloth. For stubborn stains, a mild soap solution can be used. Avoid harsh chemicals or abrasive cleaners.
- Fabric Care: The breathable mesh fabric and padded seat can be gently wiped. Do not saturate with water.
- Frame Care: Wipe metal and plastic parts with a damp cloth.
- Caster Maintenance: Periodically check casters for hair or debris and clean them to ensure smooth movement.
- Fastener Check: Regularly inspect all screws and bolts to ensure they are tight. Retighten as needed to maintain stability and safety.
- Storage: If storing the chair for an extended period, keep it in a cool, dry place away from direct sunlight.
