Old Office Chair Broken

After an old office chair is damaged, you can choose to repair or replace it based on the extent of the damage. Here are the specific solutions:

1. Minor Damage: Self-Repair

If the chair has minor issues such as loose screws, detached casters, or broken buckles, you can try to fix them yourself first:

• Loose Screws: Use the appropriate tools (such as a screwdriver or wrench) to tighten all loose screws, paying special attention to the connections between the backrest, armrests, and seat plate.
• Detached Casters: Purchase universal casters of the same size, align them with the original slots for installation, and ensure that the axles match the caster feet. If the axles are rusty, sand them down and apply lubricant.
• Broken Buckles: Buy buckles of the matching model online for replacement. If you need a temporary solution, apply high-temperature structural adhesive (such as AB glue) to the broken area, press it firmly, and let it sit for several hours until fully cured.

2. Moderate Damage: Partial Replacement

If the damage involves core components, targeted replacement is required:

• Deformed Frame/Cracked Seat Plate: Measure the dimensions of the original parts (such as the length of the frame and the width of the seat plate), and purchase corresponding models online for replacement. When installing, ensure that the screw holes are aligned to avoid secondary damage.
• Failed Gas Lift: If the backrest cannot stay upright or the height adjustment function fails, the gas lift needs to be replaced. Turn the chair upside down and use a pipe wrench to remove the old gas lift. When installing the new one, choose appropriate screws (for example, a non-standard 10*1 screw can be replaced with a standard No. 10 screw, with a recommended length of 30 mm) and ensure they are firmly fixed.
• Damaged Wheels: Check if the caster feet are bent or deformed. If damaged, purchase a complete set of matching wheels (pay attention to the shape and size of the axles). When removing, use a screwdriver to pry open the gap between the caster foot and the chair's contact point, or pull it out directly. Before installation, apply lubricant (such as WD-40) to the axle socket and gently tap it in with a rubber mallet until fully seated.

3. Severe Damage: Recommended Replacement

If the backrest frame is broken, the chair legs have large-area cracks, or the height adjustment and load-bearing functions are completely lost, the repair cost may be close to the price of a new chair, and the safety after repair is difficult to guarantee. In this case, it is recommended to replace the chair directly.

4. Handling of Other Common Issues

• Chair Tilt: Check if all the wheels are in contact with the ground. If the caster feet are damaged, replace them. If the wheels are normal, check if the seat plate (square metal plate) is deformed or broken.
• Chair Sinking: You can use a hose clamp or PVC pipe to fix the gas cylinder. After adjusting the chair to the appropriate height, wrap the hose clamp around the gas cylinder and tighten it. Or purchase a PVC pipe that matches the diameter of the gas cylinder, saw it open lengthwise, and slip it over the gas cylinder to prevent sliding.
