The Constant Movement of Office Chairs

The constant movement of office chairs may be caused by various factors such as design structure, loose screws, and worn-out components, and can be resolved through targeted inspections and repairs.

Normal Shaking Caused by Design Structure

Office chairs are assembled from multiple components. To ensure the flexibility of functions such as height adjustment, reclining, and rocking, a certain gap is reserved at the screw connections of the components, which cannot be completely sealed. This design inherently causes some shaking. Additionally, chairs with a rocking function can sway slightly, facilitating rest after prolonged sitting. Coupled with the rotation of the universal wheels, there will be a slight shake when sitting on the chair, which is a normal phenomenon and generally does not affect normal use.

Loose Connection Screws

This is a common cause of office chair shaking. Screws at various connection points such as the backrest, armrests, base, and chair legs may gradually loosen over time due to prolonged sitting pressure and frequent reclining and rocking, resulting in gaps between components. When pressure is applied to the body, friction between the components causes shaking. If the shaking is noticeable, re-inspect the fixing screws of the backrest and base to check for any loose screws. If any are found to be loose, tighten them with the appropriate tool.

Worn-out Components

• Lack of Lubrication in the Base Shaft: For chairs with a rocking and reclining function, the lubricating oil at the internal metal spring and shaft positions may dry out after prolonged use. At this point, friction and compression between the metals not only produce noise with every movement but also cause shaking. In this case, add an appropriate amount of lubricating oil to the base shaft to reduce friction and restore the chair's stability.
• Wear at the Connection between the Gas Cylinder and the Five-Star Base: The contact positions between the top of the gas cylinder and the base, and the bottom of the gas cylinder and the five-star base, may wear out due to prolonged weight-bearing, resulting in gaps. When the body shakes, friction noise and shaking may occur. If the wear is severe, it may be necessary to replace components such as the gas cylinder or five-star base to resolve the issue.

Incorrect Base Installation

If the seat leans forward, it may be due to incorrect installation of the base. The correct installation method is that the lever for adjusting the height while sitting on the chair should be on the right side. If it is on the left side, it indicates that the base is installed backward, and in this case, simply reinstall the base correctly.
