5. Operating Instructions
5.1 Height Adjustment
To adjust the seat height, locate the lever on the right side beneath the seat. Pull the lever upwards while seated to lower the chair, or pull the lever upwards while standing to raise the chair. Release the lever at your desired height. The seat height is adjustable by 10 cm, typically ranging from 47 cm to 57 cm.
5.2 Rocking Function
The chair features a rocking function with an adjustable tilt tension. To activate the rocking motion, pull out the lever on the right side. To lock the chair in an upright position, push the lever inwards. The rocking range is approximately 95° to 120°. Adjust the tension of the rocking motion by turning the round knob located beneath the seat. Turn clockwise to tighten (less rocking) and counter-clockwise to loosen (more rocking).
5.3 Flip-up Armrests
The armrests can be flipped up by 90 degrees. This feature allows the chair to be pushed further under a desk, saving space when not in use. Simply lift the armrests upwards until they lock into the vertical position. To return them to the horizontal position, pull them down.
5.4 Lumbar Support and Backrest Storage
The chair's backrest is ergonomically designed to provide 3D lumbar support, conforming to the natural curve of the human spine. Additionally, the backrest features a storage basket design, allowing you to conveniently store documents, books, or pens, keeping your workspace tidy.
