Office Chair Repair

The repair methods for office chairs vary depending on the component issues. Here are the repair steps for common problems:

Repair of the Backrest Gliding Mechanism of the Sihoo C500 Second-Generation Deluxe

If the backrest bone block is loose and fails to stay in place, the back cover needs to be removed for repair. Operation Steps:

1. Gently pry open the lower edge of the backrest cover with your fingers or a tool, and remove the cover.
2. Remove the five screws securing the internal components and disassemble the rear aluminum alloy cup holder.
3. Check the connection point of the bone block for wear or deformation. Replace the parts if necessary and reassemble.

Repair of the Wheels on an Office Swivel Chair

When the wheels are loose or fall off, they can be reset by prying. Operation Steps:

1. Insert needle-nose pliers into the gap between the wheel and the footrest, and gently pry to separate the wheel from the axle.
2. Align the wheel with the hole on the footrest, press firmly, or tap lightly with a rubber mallet until it is fully seated.

Repair of Wear on the Back of a Leather Executive Chair

Minor wear can be treated by cleaning and color restoration. Operation Steps:

1. Spray a multi-purpose cleaner on the worn area and wipe it clean with a soft cloth to remove dirt and old coatings.
2. Select a dedicated color restoration paste according to the leather color, apply it evenly with a sponge or brush, and polish with a leather conditioner after drying.

Repair of an Office Chair Tilted to One Side

Chair tilting is often caused by damaged or improperly installed wheels and requires systematic troubleshooting. Operation Steps:

1. Check the Wheel Status: Invert the chair and observe whether each wheel foot is in contact with the ground, ensuring there are no breaks or deformations. If the wheels are damaged, purchase replacement parts of the same model (you can obtain the model number from the manufacturer or take the old wheels to an office supplies store for matching).
2. Remove the Old Casters:
   • Try by hand: Hold the wheel with one hand and the bottom of the chair with the other, and pull firmly.
   • Use a tool: If it cannot be pulled out, insert a flat-head screwdriver into the gap between the wheel foot and the chair, and slowly pry until the wheel is loose by about 1 centimeter, then pull it out again.
   • Screw-fixed type: Directly loosen the fixing screws with a screwdriver and remove.
3. Lubricate and Install:
   • Spray a small amount of WD-40 lubricant (or apply a pea-sized amount of petroleum jelly) into the socket on the chair base.
   • Align the wheel rod with the hole on the base, push gently by hand first, and if it is not seated, tap lightly on the top of the wheel rod with a rubber mallet (avoid hitting the edge of the wheel) until it is fully inserted.
4. Test and Adjust: Place the chair upright and sit on it to test stability. If it is still tilted, check whether the seat plate is deformed or damaged, and replace it if necessary.

Precautions: Wear gloves during operation to prevent scratches, and control the force when using tools to avoid damaging components. If the problem is complex or involves core components such as the gas cylinder, it is recommended to contact a professional repair technician.
