Office Chair Base Noise

The noise from an office chair base may be caused by loose screws, cracks or looseness in the five-star base, foreign objects stuck in the casters or damaged bearings, structural looseness, or poor lubrication, and can be resolved through targeted solutions.

1. Loose Screws
   The screws at the connection points of the office chair's backrest, seat cushion, armrests, and base are prone to loosening under long-term stress, resulting in friction or collision sounds like "creaking/squeaking" during movement, especially noticeable when leaning back and forth or swaying side to side, with no noise when stationary. Common loose positions include beneath the seat cushion, the backrest connecting steel plate, and the armrest base. Solution: Turn the chair upside down and use a Phillips or hex key to tighten all visible screws one by one to ensure a secure connection.

2. Cracks or Looseness in the Five-Star Base (Five-Claw Base)
   Plastic or nylon five-star bases are prone to micro-cracks due to aging, while metal bases may experience slight deformation under load due to fatigue at the welds, producing a "clunking" sound, especially noticeable when sitting down or getting up. Severe cracking can lead to deformation of the base, posing a risk of collapse. Solution: If the five-star base is cracked, replace it immediately with a new one; if it is only loose, check and tighten the connecting screws, but regularly observe for further damage.

3. Foreign Objects Stuck in Casters or Damaged Bearings
   When the casters are entangled with hair, threads, or the internal bearings are worn, pushing the chair will produce a "rustling/creaking" sound, and rotating the chair in place may also produce noise. Solution: Remove the casters and clean out any entangled objects; if the bearings are dry, apply a small amount of lubricating oil; if the casters are damaged, replace them directly (a pair costs only a few yuan).

4. Structural Looseness or Poor Lubrication
   If the screws are not fully tightened during installation or lubrication is insufficient, it can lead to increased friction between components, resulting in continuous noise. Solution: Re-check all screws to ensure they are tightened, paying special attention to the connection between the casters and the base; use a professional lubricant (such as silicone-based lubricating oil) to evenly apply to the wheel axles, pneumatic lift mechanisms, and connecting joints to reduce friction.

Daily Maintenance Suggestions: Regularly check the tightness of the screws, avoid overloading the chair, and keep the casters clean to extend the lifespan of the office chair and reduce noise. If the problem persists, it is recommended to contact a professional repair technician to inspect for structural damage.
