1. Koltuk Yükseklik Ayarı:
   Locate the adjustment lever under the right side of the seat. To raise the seat, lift the lever while taking your weight off the seat. To lower the seat, lift the lever while seated. Release the lever to lock the height. The seat height can be adjusted between 47.5 cm and 56.5 cm.
2. Sallanma Fonksiyonu ve Eğim Gerginliği:
   The chair features a rocking function for relaxation. To activate the rocking function, pull the adjustment lever outwards. To lock the chair in an upright position, push the lever inwards. The tilt tension can be adjusted by rotating the control knob located under the seat. Turn clockwise to increase tension (making it harder to recline) and counter-clockwise to decrease tension (making it easier to recline).
3. Ayarlanabilir Baş Desteği:
   The headrest can be adjusted vertically to provide optimal neck and head support. Gently push or pull the headrest up or down to your desired height.
4. Esnek Bel Desteği:

5. Açılır Kolçaklar:
   The armrests can be flipped up by 90 degrees, allowing you to push the chair closer to your desk or save space when not in use. Simply lift the armrests upwards until they lock into the vertical position.
