Squeaking Office Chair

Squeaking in an office chair may be caused by loose connecting screws, lack of lubrication in the base axle, wear and tear at the connection between the gas lift and the five-star base, aging and deformation of plastic frame components, dry or loosely installed wheel bearings, etc. Solutions include tightening screws, applying lubricant, and replacing parts.

Loose connecting screws are a common cause. Screws at connection points such as the backrest, armrests, base, and chair legs may gradually loosen due to prolonged sitting pressure or frequent reclining movements, creating gaps between components that produce squeaking sounds when pressure is applied. In this case, simply tighten all loose screws with a tool to eliminate most of the noise.

Lack of lubrication in the base axle can also lead to squeaking. In chairs with a rocking and reclining function, the internal metal springs and axle positions may dry out over time, causing metal-to-metal friction and noise. Apply an appropriate amount of lubricant to the metal axles and connection gaps to reduce friction and resolve the squeaking issue.

Wear and tear at the connection between the gas lift and the five-star base should not be overlooked. The contact points between the top of the gas lift and the base, and the bottom of the gas lift and the five-star base, may develop gaps due to prolonged weight-bearing, resulting in friction and noise when the body moves. If the wear is severe, replace the gas lift or the five-star base; if the wear is minor, try applying lubricant to the contact points to reduce friction.

Aging and deformation of plastic frame components are more common in low-priced chairs. Thin plastic frames may slightly deform under prolonged sitting pressure, creating structural gaps that produce friction and noise, which are difficult to completely repair. In this case, consider replacing the chair or try adding adhesive paper shims at the connection points to reduce friction and gaps.

Dry or stuck wheel bearings are also easily overlooked. When the chair moves, the internal bearings of the wheels may lack oil, causing dry rolling friction and noise. Replace the casters with silent PU casters or apply lubricant to the bearings to resolve the noise issue.

Additionally, loosely installed screws or loose connections of plastic or metal components on the chair back may also cause squeaking. Carefully inspect and secure all screws to ensure stable connection points.
