Office Chair Replacement

Office chair replacement should be carried out based on specific component issues or overall replacement needs. Common replacement components include tray springs, wheels, bases, etc. Companies may also conduct centralized replacements due to upgrade requirements.

1. Tray Spring Replacement
If the reclining adjustment function of the office chair fails, it may be due to a damaged tray spring. To replace it, first flip the chair over, locate the spring assembly at the connection between the tray and the backrest, use a screwdriver or wrench to remove the fixing screws, take off the old spring, and install the new one. Ensure that the spring direction is consistent with the original position to avoid incorrect installation leading to abnormal adjustment functions. This operation can restore the chair's reclining elasticity and enhance comfort.

2. Wheel Replacement
Damaged wheels can make it difficult to move the chair or scratch the floor. To replace them, use pliers to grip the connection between the wheel and the chair leg and pull upwards forcefully; if the wheel is stuck, lightly tap the top of the wheel with a hammer to assist in removal. When installing new wheels, align the wheel axle with the hole on the chair leg and press vertically until fully embedded. If unsuccessful on the first attempt, try multiple times to ensure the wheels are securely installed. After replacement, check that the wheels rotate smoothly to avoid jamming.

3. Base Disassembly and Replacement
The base of an adjustable-height or swivel chair (such as a damaged pneumatic rod or broken chassis) requires overall replacement. To disassemble, first lay the chair down, use a wrench to remove the screws connecting the base to the chair body, separate the base, and then install the new base. Ensure that the screw holes are aligned and tightened securely. If replacing the pneumatic rod, choose one that matches the original model to avoid abnormal height adjustment functions or safety hazards due to incompatible specifications.

4. Centralized Replacement Plan for Companies
Some companies may conduct centralized replacements due to office environment upgrades or brand unification requirements. For example, ByteDance once initiated a centralized replacement plan for office chairs in China, replacing Humanscale brand office chairs with 'Qingxian s1'. The plan was scheduled to run from August 2026 to the second quarter of 2027, covering domestic work areas. Such replacements are usually uniformly purchased and installed by the company, requiring no self-operation by employees, but necessitating cooperation with relocation or temporary workstation adjustments.

Precautions: When replacing components yourself, turn off the chair's height adjustment function (if applicable) to avoid accidental chair movement during operation; for high-pressure components such as pneumatic rods, it is recommended to contact professionals for replacement to prevent explosion risks. Before centralized replacement by companies, assess the workstation layout to ensure that the size of the new chairs matches the available space.
