Noise When Reclining Office Chair

When an office chair reclines, it may produce noise, which can be caused by various factors such as loose connecting screws, lack of lubrication in the base axle, or worn-out components. Specific solutions are required based on the cause. Here is a detailed analysis and solutions:

1. Loose Connecting Screws
The connecting screws at the backrest, armrests, base, and chair legs may become loose due to long-term stress or frequent shaking, creating gaps between components. When reclining, the metal or plastic parts rub against each other, producing abnormal noise. Solution: Use a screwdriver to check and tighten all loose screws one by one, focusing on the connections between the base and chair legs, and the backrest and base.

2. Lack of Lubrication in the Base Axle
For chairs with a rocking and reclining function, if the lubricating oil in the internal metal springs and axles dries up, direct friction between metal parts will produce a harsh sound. Solution: Apply specialized lubricating oil (such as WD-40 or white lithium grease) to the axle and spring connections. After application, recline the chair several times to allow the lubricating oil to fully penetrate.

3. Wear at the Connection Between the Gas Cylinder and the Five-Star Base
The contact areas between the top of the gas cylinder and the base, and the bottom of the gas cylinder and the five-star base may develop gaps due to wear after long-term weight-bearing. When reclining, friction between the gas cylinder and metal parts produces a creaking sound. Solution: If the wear is minor, apply lubricating oil to the contact areas; if the wear is severe, replace the gas cylinder or five-star base.

4. Aging and Deformation of Plastic Frame Components
Low-priced chairs often use thin plastic frames, which may deform under long-term pressure, causing structural compression and friction between components. Such abnormal noise is usually difficult to completely repair. Solution: If the deformation is minor, try applying lubricating oil or petroleum jelly to the contact areas; if the deformation is severe, it is recommended to replace the chair.

5. Internal Structure Issues
For chairs that have been used for a long time, the internal springs may lose elasticity, deform, or rust, or the supporting metal rods and plastic parts may wear out or become damaged. Solution: If the issue is with the springs, adjust their position or replace them with new ones; if the supporting structure is damaged, repair or replace the specific components as needed.

6. Fabric Friction
If the seat cushion and backrest use different fabric materials, friction between the fabrics may produce noise when reclining. Solution: Apply a small amount of petroleum jelly or specialized lubricant to the fabric contact areas to reduce friction noise.

7. Friction Between Chair Legs and the Floor
If the material of the chair legs does not match the floor (such as metal chair legs sliding on a tiled floor), or if the floor is uneven, friction between the chair legs and the floor will produce noise when reclining. Solution: Put rubber anti-slip pads on the chair legs; if the floor is uneven, adjust the height of the chair legs or place thin shims under the lower chair legs to level them.
