Office Chair Makes Noise
An office chair making noise can be caused by various reasons, and troubleshooting and solutions can be implemented based on different situations:
Loose screws The screws at the connection points of the chair's backrest, seat cushion, armrests, and base are prone to loosening due to long-term stress, resulting in friction or collision sounds like 'creaking/squeaking'. Such noises are noticeable when leaning back and forth or swaying side to side, but not when stationary. The locations are mostly concentrated under the seat cushion, the connecting steel plate of the backrest, or the base of the armrests. Solution: Turn the chair over and use a cross or hexagonal wrench to tighten all visible screws one by one, focusing on the connection points of the backrest, seat cushion, armrests, and base.
Worn or rusty gas lift/height adjustment rod Long-term weight bearing or dust accumulation on the gas lift can cause dry friction, resulting in 'clicking/squeaking' sounds during height adjustment. Slight shaking when sitting can also trigger the noise, which comes from the middle of the chair. If the noise is severe, it may be accompanied by vibrations throughout the chair. Solution: Replace the gas lift directly to avoid safety hazards from continued use.
Cracked or loose five-star base (five-claw base) Five-star bases made of plastic or nylon are prone to aging and cracking, while metal bases may suffer from fatigued welds. Deformation under weight can cause cracking sounds, especially noticeable when sitting down or getting up. If the cracking is severe, the base may deform or even collapse. Solution: Replace the five-star base immediately to prevent accidents.
Lack of lubrication in the rocking base/reclining pivot Dry friction in the reclining pivot or springs due to lack of lubrication can cause a piercing, continuous creaking sound, located at the metal plate directly under the seat cushion. Solution: Spray WD-40, sewing machine oil, or grease onto the gas lift, reclining pivot, and connection points of the five-star base. After spraying, move the parts back and forth a few times, and the noise should mostly disappear. Note: Avoid using cooking oil, as it will attract dust and become smelly.
Foreign objects stuck in the casters or damaged bearings When hair, thread, or other debris gets stuck in the wheels, or the bearings are worn, pushing the chair can produce 'rustling/creaking' sounds, and turning it in place can also make noise. Solution: Remove the wheels to clean out any debris. If the bearings are dry, lubricate them with oil. If the wheels are damaged, replace them directly.
Broken frame of the seat cushion/backrest The internal frames of mesh or fabric chairs can age and crack, producing cracking sounds under stress, which poses a safety hazard. Solution: Once the frame is broken, it cannot be repaired and the entire chair must be replaced.
Uneven floor An uneven floor can cause the chair legs to bear uneven weight, resulting in shaking or creaking sounds. Solution: Use pads to adjust the height of the chair legs to ensure stable contact with the ground.
Prolonged use Long-term use can lead to aging of components or deformation of the seat, causing noise. Solution: Replace aged components. If the seat or backrest has cracks or deformation, use high-quality materials for replacement to extend the lifespan.
