Office Chair Repair

Office chair repair requires targeted measures based on specific issues. Here are the solutions to common problems:

Loose Backrest Bones of Sihoo C500 Second Generation Deluxe That Do Not Lock Tightly

If the backrest bones are loose and do not lock tightly, the back cover needs to be removed for repair. The specific steps are: Pry off the back cover from the lower edge, remove the 5 screws securing the back cover, and take off the aluminum alloy cup holder. During this process, pay attention to the specifications and positions of the screws to avoid losing or misplacing them. After repair, check the locking effect of the backrest to ensure its stability.

Office Chair Leaning to One Side

1. Check the Contact Between the Wheels and the Ground:

   • Place the chair upright and upside down to observe whether all the wheel feet are in contact with the ground. If the ground is uneven, the wheels may not all be in contact with the ground when not seated, and the chair will lean to the lower side when seated.
   • Invert the chair and check each wheel foot for signs of damage (such as bending or deformation). If a wheel foot is damaged, the chair will lean in the direction of the damage.

2. Replace Damaged Wheels:

   • If damaged wheels are found, new matching wheels need to be purchased. You can contact the manufacturer with the chair model for an order, or take an old wheel to an office supplies store to find a matching replacement set after removing it. Pay attention to matching the shape and size of the wheel axles to avoid installing incompatible wheels.

3. Remove Old Casters:

   • Hold the caster wheel with one hand and the bottom of the chair with the other hand and pull firmly. If it does not come out, insert the blade of a flat-head screwdriver into the small gap between the wheel foot and the chair contact point and use it as a lever to operate slowly back and forth, pulling out about 1 centimeter and then pulling the wheel foot again.
   • In a very small number of cases, the casters are fixed with screws. If a screw head is visible, use a screwdriver to loosen the screw and then remove the caster.

4. Lubricate and Install New Casters:

   • Apply a small amount of spray lubricant (such as WD-40) to each socket on the chair base. Insert the straw into the spray nozzle and insert it into each socket for a quick half-second spray. If there is no lubricant spray, apply a pea-sized amount of petroleum jelly to each wheel axle.
   • Tap the new casters into the chair sockets with a rubber mallet, ensuring that the caster rods are aligned with the base. First, push gently with your hand. If it is not in place, tap gently with a rubber mallet until the rod is fully inserted into the base. If the caster design allows, tap near the base of the stem to reduce the risk of deformation or breakage.

5. Test and Further Inspection:

   • Invert the chair and sit on it to test the new wheels. If they roll smoothly and evenly and no longer lean, the repair is complete; if it still leans, check whether the seat plate is damaged. Lay the chair on its side, find the metal seat plate (usually a square black painted steel plate located at the bottom of the seat), and check whether its connection is secure.

Slight Wear on the Back of a Leather Executive Chair

If there is slight wear on the back of a leather executive chair, it needs to be cleaned first and then repaired. Clean the damaged area with a multi-purpose cleaner to remove stains and impurities, and then proceed with the repair after it is dry. For repair, you can choose a leather repair paste or special touch-up paint and match it according to the color and texture of the leather to ensure a natural repair effect.
