Then, align the backrest with the upper holes of the armrests and the back of the seat. Secure the backrest to the armrests and seat.

5. Gebruiksaanwijzing
Your tectake office chair offers several adjustment features to customize your seating experience for optimal comfort and ergonomic support.
5.1 Hoogteverstelling
Om de zithoogte aan te passen:
- Om te verhogen: While standing, pull the lever located on the right side of the seat upwards. The seat will rise automatically. Release the lever when the desired height is reached.
- Om te verlagen: While seated, pull the lever located on the right side of the seat upwards. The seat will lower. Release the lever when the desired height is reached.
5.2 Tilt Mechanism and Tension Adjustment
The chair features a continuous tilt mechanism that allows the backrest and seat to recline together. The tension of this tilt can be adjusted to suit your weight and preference.
- To activate/deactivate tilt: Pull the same lever used for height adjustment outwards to enable the tilt function. Push it inwards to lock the chair in an upright position.
- Om de kantelspanning aan te passen: Rotate the round knob located underneath the front of the seat. Turn clockwise to increase tension (making it harder to recline) and counter-clockwise to decrease tension (making it easier to recline).
5.3 Ergonomische ondersteuning
The chair's design, including the padded backrest and headrest, provides ergonomic support to promote a healthy posture and reduce fatigue during extended use.
