Office Chair Handle Illustration

The adjustment functions and operation methods of office chair handles vary depending on the type of chair, mainly divided into three categories: ordinary pneumatic swivel chairs, multifunctional office chairs, and mechanical lifting chairs. The specific operations are as follows:

Ordinary Pneumatic Swivel Chairs If the chair is equipped with a single handle, its function is height adjustment: to raise the seat, simply lift the handle upwards; to lower the seat, sit on the chair, maintain your body weight, and then lift the handle upwards, utilizing the compression characteristics of the pneumatic rod to achieve descent. If the chair has two handles, they control different functions separately: one handle is for height adjustment (operation as above), and the other is for backrest angle adjustment—after pulling the handle, rotate it to adjust the recoil force or flattening angle of the backrest, and the backrest will be fixed in the current position when the handle is released.

Multifunctional Office Chairs (e.g., Sihoo M18) The handles of such chairs have more diverse functions, typically including the following adjustment methods:

1. Height Adjustment: Pull the handle below the seat to adjust the seat height up or down using the pneumatic rod. It is recommended to slightly lift your hips during operation to avoid uneven force on the pneumatic rod.
2. Reclining Function: Pull out the handle to activate the reclining mode, allowing the backrest to recline with your body; push in the handle to lock the current angle and prevent accidental rebound. Some models are also equipped with a reclining tension adjustment knob, which can be rotated to adjust the resistance of the backrest to accommodate different body weights or usage habits.
3. Armrest Adjustment: Press the button on the side of the armrest to move the armrest height up or down, meeting the needs of different desk heights or arm support.
4. Backrest Angle: Some models require pulling up the lever below the backrest to adjust the inclination of the backrest by moving it up or down, and the angle is fixed when the lever is released.

Mechanical Lifting Chairs Such chairs use a lead screw structure to adjust the height by rotating the handle: when rotating the handle counterclockwise, the lead screw rotates to push the seat upwards; when rotating clockwise, the seat descends. Each full rotation typically adjusts the height by one pitch, providing high adjustment precision but requiring continuous manual rotation, which can be time-consuming.

Precautions:

• When adjusting the height, it is recommended to sit on the chair and slightly lift your hips to reduce local stress on the pneumatic rod or lead screw and extend the service life.
• After completing the adjustment, ensure that all components (such as the backrest and armrests) are firmly fixed to avoid safety hazards caused by looseness during use.
• The operation logic of some models (such as the Sihoo M18) may vary slightly due to design differences. It is recommended to refer to the specific product manual or consult after-sales personnel.
