Office Chair Breakage Repair

The repair of a broken office chair requires selecting targeted methods based on the broken part and type to ensure the restoration of safety and functionality.

If it is a wooden structure breakage (such as armrests or chair legs), the repair process should follow these steps:

1. Bond the broken part: Apply a strong woodworking adhesive (such as white glue or epoxy resin glue) evenly to the broken edges, align them, and secure them with clamps for at least 24 hours to ensure the adhesive fully cures.
2. Fill the break: Mix wood powder with a similar color to the wood with adhesive to form a paste and fill the gaps, or directly use wood putty to level the surface. After drying, sand it from coarse to fine grit until the surface is smooth.
3. Restore the appearance: If the original chair has a painted surface, sand the repaired area with fine sandpaper and then spray on paint of the same color, or cover the marks by drawing wood grain patterns. If it is treated with clear varnish, sand the local area and reapply clear varnish.

If it is a metal structure breakage (such as chair legs or brackets), it is necessary to evaluate the degree of breakage first:

1. Repairable by welding: If the break is in a steel pipe or metal connector and the broken surface is flat, contact a professional welder to repair it using argon arc welding or electric welding. After welding, sand the weld points and spray on anti-rust paint.
2. Severe breakage or load-bearing parts: If the break involves key load-bearing structures such as the connection between the chair legs and the seat plate, or the broken surface is irregular and cannot be welded, it is recommended to directly contact the manufacturer to replace the original parts or entrust a professional furniture repairer to handle it to avoid safety hazards caused by self-repair.

If it is a tilting problem (not a breakage but structural imbalance), follow these steps to troubleshoot:

1. Check the wheels and the ground: Confirm whether the wheels are damaged or stuck, and replace the damaged wheel feet. If the ground is uneven, use adjustable foot pads or level the ground.
2. Check the deformation of the seat plate: If it is a metal seat plate, check whether the connection between it and the chair legs is loose, and tighten the screws with a wrench. If the seat plate is severely deformed, replace it with a new one.

Special reminder: Breakage of load-bearing structures (such as the connection between the chair legs and the seat plate) may affect usage safety. Non-professionals should not attempt self-repair. It is recommended to contact the manufacturer or a professional repairer first.
