Office Chair Under-Handle

The main functions of the handle under the office chair include adjusting the backrest rebound force, adjusting the chair height, and some also have the function of adjusting the tightness of the lumbar support or the position of the backrest.

Adjusting the backrest rebound force: The rebound force of the office chair's backrest is crucial for the user's comfort and lumbar support. By rotating the handle under the office chair, the support strength of the backrest can be changed. Generally, rotating the handle clockwise will increase the rebound force of the backrest, making it harder and providing stronger support; while rotating it counterclockwise will decrease the rebound force, making the backrest softer and suitable for scenarios requiring a more relaxed sitting posture. This adjustment function enables the office chair to adapt to the weight and sitting habits of different users, providing a personalized support experience.

Adjusting the chair height: Adjusting the height of the office chair is another common function. By rotating the handle under the office chair up and down (usually a rotating rod), the chair can be raised or lowered. This design allows users to easily adjust the chair height according to their own height and desk height, ensuring that their feet are flat on the ground and their knees and hips are kept level, thereby maintaining a correct sitting posture and reducing fatigue and discomfort caused by prolonged sitting.

Adjusting the tightness of the lumbar support or the position of the backrest: Some ergonomic chairs have more complex designs, and their handles also have the function of adjusting the tightness of the lumbar support or the position of the backrest. By rotating or pushing the handle, the tightness of the lumbar support can be adjusted to make it more in line with the user's lumbar curve, providing more precise lumbar support. At the same time, some chairs also allow the front-back position of the backrest to be adjusted through the handle to adapt to the body proportions and sitting needs of different users, further enhancing the comfort and healthiness of use.
