Office Chair Repair

Office chair repair requires different methods depending on the specific issue. Here are the repair steps for common problems:

1. Repair of the backrest gliding mechanism of the Sihoo C500 Second Generation Deluxe If the backrest bone blocks are loose and do not stay in place, the aluminum alloy cup holder needs to be disassembled and tightened. First, pry open the back cover from the bottom, remove the 5 screws securing the back cover, and then remove the aluminum alloy cup holder. Check if the connection points of the bone blocks are worn or deformed. If necessary, replace the parts and reassemble them, ensuring that the screws are tightened to a fixed state.

2. Repair of minor abrasions on the back of a leather executive chair For minor abrasions on the leather surface, first clean the damaged area. Spray a multi-purpose cleaner (such as a neutral leather cleaner) onto the abrasion and gently wipe away dirt and dust with a soft cloth. After drying, apply leather repair paste or a specialized color-restoring paste to fill in the abrasion, spreading it evenly with a sponge and allowing it to dry naturally. If the abrasion is deep, it is recommended to contact a professional leather repair service.

3. Repairing an office chair that leans to one side

• Check wheel contact with the ground: Place the chair upright and upside down to confirm that each wheel foot is in contact with the ground. If the ground is uneven, the chair will lean towards the lower side; if the wheel feet are bent or deformed, the wheels need to be replaced.
• Replace damaged wheels:
  • Remove old wheels: Grasp the wheel and the bottom of the chair with your hands and pull it out forcefully; if it is stuck, insert a flat-head screwdriver into the gap between the wheel foot and the chair as a lever to slowly pry it open, pulling it out about 1 cm before pulling again; a very small number of wheels are fixed with screws and need to be removed by loosening the screws with a screwdriver.
  • Install new wheels: Spray a small amount of lubricant (such as WD-40) on the chair base socket or apply a pea-sized amount of petroleum jelly; align the new wheel rod with the socket, first push it gently with your hand, and if it is not stuck, tap the base of the wheel rod lightly with a rubber mallet to ensure it is fully inserted.
• Test and adjust: Place the chair upside down and sit on it to test if the wheels roll smoothly. If it still leans, check if the seat plate is damaged. Lay the chair on its side to find the metal seat plate (usually a square black steel plate connecting the single-leg column to the bottom of the seat) and check for deformation or breakage, replacing the seat plate if necessary.

Precautions: Wear gloves during repair to avoid scratches; be careful with the force when using tools to prevent damage to the chair structure; if the problem is complex or involves internal mechanical structures, it is recommended to contact a professional repair technician.
