Office Chair Rotation Fixation

The rotation function of office chairs can be fixed or locked using the following methods, and the specific operation should be selected according to the chair's design:

1. Locking and Unlocking Function (Rotary Rod Type) Some office chairs are equipped with a push-pull rotary rod at the gas lift or the bottom of the seat, enabling rotation locking through inward or outward pulling. Pushing the rotary rod inward fixes the chair in its current state (including the rotation angle and the backrest angle), while pulling the rotary rod outward releases the lock and restores free rotation. When operating, pay attention to the position of the rotary rod, which is usually located beneath the seat or on the side, requiring squatting or bending over to observe.

2. Rotary Knob Locking If the chair has a circular rotary knob at the bottom (mostly made of metal), the resistance can be adjusted by rotating it. Rotating the knob clockwise gradually increases the resistance of the backrest or the rotating structure. When the resistance reaches its maximum, the backrest and rotation functions are locked; rotating it counterclockwise restores mobility. Some designs integrate the backrest locking and rotation locking functions, and the specific operation logic should be confirmed through the instruction manual.

3. Toggle Switch Locking Some office chairs are equipped with toggle switches on the side or at the bottom, usually marked with "Lock" and "Unlock" labels. After moving the toggle switch to the "Lock" position, the backrest tilt and rotation functions are simultaneously fixed; moving it back to the "Unlock" position restores free adjustment. When operating, ensure that the toggle switch is fully in place to avoid lock failure due to poor contact.

4. Dedicated Fixer (Physical Fixation) If complete rotation prohibition is required (such as in medical or laboratory settings), a seat rotation fixer can be selected. This type of accessory achieves physical fixation by fitting the diameter of the gas lift (approximately 95% of the common thick tube specifications are compatible). After installation, the chair will not be able to rotate. For example, the SoChair Ergonomic Home Adaptation Fixer is fastened with buckles or screws and is suitable for long-term fixation needs. Before installation, measure the diameter of the gas lift to ensure compatibility of the accessory.

Precautions:

• Before operating, confirm the design type of the chair to avoid accidentally touching other function keys (such as height adjustment).
• If the locking function fails, it may be due to wear of the internal mechanical structure or air leakage in the gas lift, and the manufacturer should be contacted for repair.
• When children or individuals with mobility impairments use a fixed chair, ensure that the structure is stable to avoid the risk of tipping over.

It is recommended to refer to the chair's instruction manual or contact the manufacturer for precise operation guidance first, as designs may vary among different brands (such as Herman Miller and Steelcase).
