Office Chair Makes Noise When Sitting

An office chair making noise when sitting can be caused by various reasons, which can be resolved through targeted solutions. The specific causes and solutions are as follows:

Loose connecting screws are one of the common causes. The screws at the connection points of the backrest, armrests, base, and chair legs may gradually loosen due to long-term sitting pressure and frequent reclining movements, creating gaps between components. When the body presses down, these components rub against each other, producing abnormal noises. Additionally, loose connections at the plastic or metal parts of the backrest, as well as long-term wear at the connection points of low-quality chairs, can also cause noise. The solution is to tighten all loose screws, which can effectively eliminate such noises.

Lack of lubrication in the base swivel can also trigger abnormal noises. For chairs with a rocking and reclining function, the internal metal springs and swivel positions may dry out over time, causing metal-to-metal friction and pressure. Any movement can then produce sounds, which is a normal form of wear and tear. Applying a bit of lubricant to the metal swivels and connection gaps can reduce friction and eliminate the noise.

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, as well as the bottom and the five-star base, can develop gaps due to long-term weight-bearing wear. When the body moves, friction and abnormal noises occur. The treatment method is similar to that for the base swivel; apply lubricant to the connection gaps to alleviate the noise caused by wear.

Aging and deformation of the frame's plastic parts are more common in low-priced chairs. These chairs often use thin plastic frames that can slightly deform and experience structural compression under long-term sitting pressure. The resulting gaps and friction can continuously produce abnormal noises, and it is generally difficult to completely repair them. If the chair is not of high value, consider replacing it with a new one.

Dry and stuck wheel bearings can easily be mistaken for noise coming from the main body of the chair. When the chair moves, the lack of oil in the wheel bearings causes dry rolling friction, producing noise. You can replace all the casters with silent PU casters or place a layer of adhesive tape between the wheels and the hole walls to fill the gaps and reduce friction, thereby eliminating the noise.

In addition, installation issues and poor product quality can also cause abnormal noises in office chairs. If the screws are not installed stably after purchasing the product, or if you buy products from obscure brands to save money, resulting in unqualified product components, abnormal noises may occur. For installation issues, reinstall the screws; for product quality issues, it is recommended to replace the chair with a reliable one.
