Office Chair Makes Noise

You can try the following methods to resolve unusual noises from your office chair:

1. Check for Installation Issues
The most common cause of unusual noises in office chairs is unstable screw installation. After prolonged use, screws may loosen due to vibrations or uneven stress, leading to friction between components and resulting in noise. Check all screws (such as those at the chair legs, backrest, and armrest connections), especially the connection between the five-star base and the chair body, to ensure they are tightened. If any are loose, use a tool to retighten them.

2. Address Product Quality Issues

• Friction between the Five-Star Base and Casters: If the noise comes from the connection between the five-star base and the nylon casters (such as ground friction sounds or squeaking at the connection points between the insert rod and the casters), it may be due to wear or insufficient lubrication from long-term use. Replace them with silent PU casters to reduce friction with the ground; or apply a small amount of lubricant (such as WD-40) to the connection points to lower the friction coefficient.
• Gap between the Chair Body and Hole Wall: If there is a gap between the chair body (the connection between the chair body and the base) and the hole wall, it may cause friction sounds due to shaking. Place a layer of adhesive paper or thin rubber sheet in the gap to fill it and cushion the vibrations, thereby eliminating the noise.

3. Resolve Issues with the Lifting Column
The lifting column is a core component of the office chair. If it lacks internal lubrication or has dust inside, it may produce a "squeaking" sound during lifting or operate roughly. Apply lubricant (such as white lithium grease) evenly to the surface of the metal rod of the lifting column and around the sealing ring. Slide it up and down several times to allow the lubricant to fully penetrate, restoring smooth operation and eliminating the noise.

4. Distinguish Normal Loosening
Office chairs often have a single-point support structure (such as a pneumatic rod connecting the chair body to the five-star base). After prolonged use, slight loosening may occur, which is normal. When the recline angle reaches its maximum, the chair back may touch the base, causing a brief noise due to component collision. Such situations do not require special treatment, but it is necessary to regularly check if the screws on the base are loose to prevent structural damage from worsening due to loosening.

Precautions: Before operating, ensure the office chair is in a stable state (such as leveling the chair legs) to avoid tipping due to loose components; choose specialized lubricants to avoid corroding plastic or metal components; if the noise persists or is accompanied by structural shaking, it is recommended to contact after-sales service for inspection to rule out safety hazards such as component breakage.
