Office Chair Noise

Office chair noise is usually caused by loose connecting screws, lack of oil in the chassis pivot, wear and tear at the connection between the gas rod and the five-star base, aging and deformation of the plastic frame components, and dry and stuck wheel bearings. It can be resolved by tightening screws, lubricating components, adjusting the structure, or replacing the chair.

1. Loose Connecting Screws
   Screws at the connection points of the backrest, armrests, chassis, and chair legs may loosen due to long-term stress or frequent shaking, creating gaps between components. When pressure is applied, friction generates a creaking sound. Solution: Use tools to tighten all loose screws, focusing on the connection points between the chassis and chair legs, and the backrest and seat cushion.

2. Lack of Oil in the Chassis Pivot
   In chairs with a rocking and reclining function, when the lubricating oil on the internal metal springs and pivots dries up, the metal components rub directly against each other, producing noise when moved. Solution: Apply lubricating oil (such as professional lubricating oil or a small amount of cooking oil) evenly to the metal contact points of the pivots and springs, avoiding excessive application.

3. Wear and Tear at the Connection Between the Gas Rod and the Five-Star Base
   The contact points between the top of the gas rod and the chassis, and the bottom of the gas rod and the five-star base, may develop gaps due to long-term weight-bearing wear, causing friction and noise when the body moves. Solution: Check the connection points between the gas rod and the five-star base. If the wear is severe, replace the gas rod or the five-star base; for minor wear, apply lubricating oil to reduce friction.

4. Aging and Deformation of the Plastic Frame Components
   Low-priced chairs often use thin plastic frames, which may slightly deform under long-term sitting pressure, causing structural compression and friction-generated noise that is difficult to completely repair. Solution: If the chair has been in use for a long time or the deformation is severe, it is recommended to replace it with a new one; for temporary relief, try adjusting the angle between the backrest and the seat cushion to reduce local stress.

5. Dry and Stuck Wheel Bearings
   When the chair moves, the lack of oil in the wheel bearings causes dry rolling friction, which can easily be mistaken for noise from the main body of the chair. Solution: Apply lubricating oil to the wheel bearings or replace them with new ones; avoid frequently moving the chair on rough surfaces during daily use to reduce bearing wear.

Daily Maintenance Suggestions: Regularly clean the chair to prevent dust and debris from entering the interior; check the tightness of the screws and apply lubricating oil every 3-6 months; if the chair has been in use for more than 5 years or shows significant wear, replacing it with a new one is the most direct and effective solution.
