Office Chair Parts Replacement

Replacing parts of an office chair can be done through self-repair or by seeking help from a professional team. Here are the specific operations and part information:

I. Self-Repair and Replacement Methods

If an office lift chair or gaming chair has issues such as tilting to one side or being unable to lift, you can replace parts like the chassis tray and gas lift rod by yourself. Preparation tools: A hammer (a rubber hammer is best). Operation steps:

1. Disassemble the seat: Turn the chair upside down and place it on the ground. Remove the screws that fix the bottom tray to separate it from the seat cushion.
2. Separate the chassis: Hold the seat upside down with one hand and strike a specific position on the chassis with a rubber hammer. If you don't have a rubber hammer, you can use an iron hammer with a towel underneath and strike it several times to separate the chassis from the gas lift rod.
3. Handle the gas lift rod: If the fault lies with the gas lift rod, turn the chair upside down and strike the bottom of the gas lift rod flatly with the side of the hammer. Be careful to avoid the middle button to prevent damage.
4. Replace parts: According to the location of the fault, replace the corresponding parts (such as the chassis, gas lift rod, chair legs, etc.).

II. Part Price References

The prices of different parts vary greatly, and you need to choose according to your needs:

• Chassis parts: Square turntable chassis costs 28.0 yuan, thickened electroplated five-star footrest ranges from 13.16 to 23.75 yuan, and steel thickened five-star foot costs 15.96 yuan.
• Gas lift rod parts: Hengkang explosion-proof four-stage gas lift rod costs 34.0 yuan, bar chair lift gas lift rod costs 14.4 yuan, and the price of the three-stage explosion-proof certified gas lift rod (suitable for high-end repairs) is unknown but usually higher.
• Caster parts: Alloy universal casters cost 3.36 yuan each, and the price of the silent and wear-resistant nylon type (suitable for high-end repairs) is unknown but usually higher.

III. Professional Repair and Modification Cases

• Professional repair: For example, the Guangzhou Jianhe professional team once replaced the gas lift rod, casters, and armrest screws for a high-end genuine leather boss chair. They selected suitable high-quality parts (such as explosion-proof gas lift rods and silent casters) and provided one-stop services.
• Creative modification: You can transform the报废 (scrap) middle-row seats of GL8 and other MPVs into office chairs by adding universal casters. The cost is about 300-500 yuan (depending on the seat material). These modified chairs support multi-angle adjustment and even lying flat, suitable for personalized needs.

IV. Precautions

• Safety first: Avoid violent striking during self-repair to prevent deformation or damage to the parts.
• Compatibility: The replaced parts need to match the model of the original chair, especially the gas lift rod, which needs to meet explosion-proof standards.
• Professional assistance: If the fault is complex or involves high-end chairs, it is recommended to contact a professional team to avoid secondary damage caused by improper operation.
