The chair offers several adjustment options to enhance your comfort:
- Axuste de altura do asento: Locate the lever under the right side of the seat. Pull the lever up to raise the seat. While seated, pull the lever up to lower the seat. Release the lever to lock the height.
- Función de balanceo: The same lever used for seat height also controls the rocking function. Push the lever inwards to lock the backrest in an upright position. Pull the lever outwards to enable the rocking motion.
- Axuste da tensión de inclinación: A round knob is located under the center of the seat. Rotate this knob clockwise to increase the tilt tension (making it harder to recline) or counter-clockwise to decrease it (making it easier to recline).
- Axuste do soporte lumbar: The lumbar support can be moved vertically. Adjust it to align with the natural curve of your lower back for optimal support.
- Axuste do repousacabezas: The headrest can be adjusted vertically to support your neck and head comfortably.
