Office Chair Repair

You can refer to the following methods for repairing office chairs and choose the corresponding repair strategy based on different problem types:

I. Self-Repair of a Tilted Office Chair

1. Check the contact between the wheels and the ground Place the chair upright and upside down to observe whether each wheel foot makes even contact with the ground. If the tilt is caused by an uneven floor, adjust the position of the chair. If there are signs of damage to the wheel feet (such as breakage or deformation), replace them with new ones.
2. Replace damaged wheels

• Match the wheel model: Contact the manufacturer and provide the chair model to order original wheels, or take the old wheels to an office supplies store to match a replacement set. Ensure that the shape (such as round or square) and size of the wheel axles are consistent.
• Remove the old wheels: If the wheels are directly inserted into the base, pull them out by hand. If they are difficult to pull out, use a flat-head screwdriver inserted into the gap between the wheel foot and the chair as a lever. If the wheels are fixed with screws, loosen the screws with a screwdriver and remove them.
• Install the new wheels: Apply a small amount of spray lubricant (such as WD-40) to each base socket, or apply a pea-sized amount of petroleum jelly to the wheel axles to reduce friction. Tap the casters into the sockets with a rubber mallet, ensuring that the rods are aligned with the base. First push gently by hand, and if they do not fit properly, tap lightly with a rubber mallet.
• Test the effect: Turn the chair upside down and check if the new wheels are stable. If it is still tilted, further check whether the seat plate is damaged.

II. Repair of Specific Issues with the Sihoo C500 Office Chair For the issue of loose and insecure bone blocks in the C500 second-generation premium model, the back cover needs to be removed for repair:

1. Use a tool to pry open the bottom of the chair's back cover and remove the 5 screws that secure it.
2. Remove the aluminum alloy cup holder and check whether the connection part of the bone blocks is worn or deformed.
3. Adjust or replace the bone block components according to the damage situation, and then reassemble and test the clamping effect.

III. Seek On-Site Repair Services If self-repair is difficult or the chair has complex problems (such as a damaged pneumatic rod or a broken chair back), you can contact professional on-site repair services. For example, in Yangquan, Yijia Housekeeping, Master Zhang (Yongli Furniture Repair), Master Cao, etc. provide office chair repair services. You can make an appointment by phone or through an online platform and explain the chair model and fault phenomenon so that the technician can bring the corresponding tools and parts.

Precautions: Cut off the power supply before repair (such as for electric office chairs) and wear gloves to prevent scratches. Use a rubber mallet instead of a metal hammer to avoid damaging the components. If the repair involves the pneumatic rod, it is recommended to have it handled by a professional to prevent the risk of explosion.
