Office Chair Swivel Base

Common issues and solutions for office chair swivel bases are as follows:

1. Analysis of Base Shaking Causes
Base shaking is a common problem with office chairs and can be caused by the following factors:

• Component Connection Issues: Gaps or loose screws at connection points can lead to instability between the base and the seat, gas lift, or other components. For example, some cases of shaking reported by AutoFull gaming chair users were related to incomplete tightening of screws.
• Functional Design Factors: Some chairs are equipped with a 'rocking function' (reclining and swaying), which inherently allows a certain degree of movement. This is normal design, but if the shaking is excessive or accompanied by unusual noises, the function may be damaged.
• Component Wear or Aging: Over time, mechanical connection components such as nylon slides and plastic clips may wear out, or gaps may widen due to frequent friction at joints. For instance, in cases of tray shaking, replacing worn parts can effectively resolve the issue.
• Installation Errors: Incorrect installation, such as reversing the base direction (e.g., front to back) or failing to properly insert the gas lift into the base interface, can lead to structural instability.

2. Repair and Adjustment Methods
Depending on the cause, the following measures can be taken:

• Tighten Screws: Use tools to check all screws on the base (including those connecting to the seat and gas lift) to ensure they are secure. If screws are stripped, replace them with new ones or reinforce the connections.
• Replace Worn Components: If nylon slides, plastic clips, or other components are severely worn, contact the manufacturer to purchase genuine replacement parts. For example, in tray repairs, replacing slides or clips can restore stability.
• Check Functional Design: If the chair has a built-in rocking function, confirm whether the shaking is within a reasonable range. If the function fails, check if the springs or elastic elements are damaged (e.g., the carbon-glass composite spring in the Sihoo C500二代 requires professional inspection).
• Reinstall the Base: If installation errors are suspected, refer to the instruction manual or video tutorials to ensure the base is correctly oriented and the gas lift is fully inserted into the interface.

3. Base Types and Price References
Base accessories on the market vary in price due to differences in material and function:

• Basic Models: Such as thickened swivel chair components (approximately 13.16 yuan), suitable for simple height adjustment functions.
• Rotating and Height-Adjustable Models: Priced around 18 yuan, supporting multi-angle adjustment.
• High-End Models: Such as aluminum alloy trays (approximately 47 yuan), or flagship bases using carbon-glass composite spring technology (e.g., the Sihoo C500二代), which offer a superior reclining experience but at a higher price.

4. Prevention and Daily Maintenance

• Avoid rough use (e.g., violent reclining or spinning) to reduce mechanical wear.
• Regularly check screw tightness, especially after 1-2 years of use.
• Avoid using corrosive liquids during cleaning to prevent aging of plastic or metal components.
