Knob-Operated Office Chair

The adjustment functions of a knob-operated office chair mainly include adjusting the backrest hardness, chair height, and locking or unlocking certain features. The specific operation methods are as follows:

Adjusting Backrest Hardness: The hardness of the office chair's backrest is adjusted using a knob located beneath the chair. To increase the backrest's support and make it harder, rotate the knob clockwise. This adjustment method is suitable for work scenarios that require maintaining an upright sitting posture for extended periods or needing strong back support, such as long hours of typing or drawing. Conversely, if you want the backrest to be softer and provide more flexible support to accommodate different sitting postures and relaxation needs, rotate the knob counterclockwise to soften the backrest.

Adjusting Chair Height: The height adjustment of an office chair is usually accomplished through a lever that can be rotated up and down. To raise the chair, rotate the lever upward, and the chair will rise accordingly until it reaches the desired height. This adjustment method is suitable for users of different heights or work scenarios that require adjusting the chair height to match the desk height. Conversely, if you need to lower the chair height, rotate the lever downward, and the chair will descend smoothly until it reaches the appropriate position.

Locking and Unlocking Functions: Some office chairs are also equipped with locking and unlocking functions to fix the chair's current state or allow for free adjustment. To fix the chair's height, backrest angle, and other settings, push the lever inward to lock it. At this point, the chair will remain in its current state unchanged, even if external force is applied. When you need to readjust the chair, pull the lever outward to render it ineffective and unlock the chair. At this time, you can freely adjust various settings of the chair.
