Office Chair Squeaking

Office chair squeaking may be caused by installation issues, product quality problems, loose components, or specific structural failures, and can be resolved by tightening, lubricating, or replacing components.

1. Installation Issues
   If the chair's screws are not installed securely, such as those at the five-star base or backrest connections, the resulting wobbling during use can cause component friction, leading to a continuous "squeaking" sound. This is the most common cause, especially with new chairs or after frequent relocation. Solution: Check that all screws are tightened, focusing on the five-star base and the connections between the backrest and seat cushion, and use tools to secure them.

2. Product Quality Problems
   Some low-cost office chairs, due to substandard materials, may experience increased wear at the connections between the five-star base and nylon casters, or between the stem and caster joints, over time, resulting in friction sounds. A slight squeaking sound is normal, but if the sound is loud or frequent, it may indicate insufficient material strength or design flaws. Solution: Replace with silent PU casters (to reduce friction with the floor) or place adhesive tape between the chair legs and hole walls (to cushion the friction); if the problem persists, consider replacing the chair with a higher-quality one.

3. Loose or Worn Components
   If the plastic or metal components at the backrest connections are loose (such as those on poorly made chairs that have worn over time), or if the seat screws have become loose due to frequent movement, misalignment and friction at the connections can produce a "squeaking" sound. Solution: Regularly check and tighten all screws, especially those at the connections between the backrest, armrests, and seat cushion; if components are severely worn (such as cracked plastic parts), replace the corresponding parts.

4. Specific Structural Failures (e.g., Bearing Issues)
   Taking the Sihoo M18 chair as an example, if the bearing connections lack lubrication or have design flaws, a "clunking" sound may occur when leaning back, moving, or rotating. Solution: Use WD-40 Blue Can Regular (equipped with a small straw) to spray the bearing connections to eliminate friction and lubricate; if the problem is not resolved, contact after-sales service to check if the bearings are damaged.

Summary: Chair squeaking is often related to installation, materials, or component aging. Prioritize checking the tightness of screws, then determine whether lubrication, component replacement, or product upgrading is needed based on the source of the sound. If self-repair is ineffective, seek professional repair or brand after-sales service.
