Office Chair Backrest Broken - Repair Methods

If the backrest of your office chair is broken, you can refer to the following repair methods:

First, assess the damage: Carefully inspect the backrest to determine the type of damage. Check whether the connection is loose or if the material is completely broken. Identify whether the issue lies with wooden, plastic, or metal components, and also check if the internal padding has collapsed. Different types of damage require different repair approaches.

Repair methods for different situations:

• Loose connections: Prepare appropriate tools such as a screwdriver. Locate the screws and nuts, identify the loose parts, and tighten the screws with moderate force to avoid stripping. If the nuts are worn, replace them with new ones.
• Broken backrest components:
  • Glue adhesion: Choose suitable glue, such as superglue, AB glue (in a 50:50 ratio), or metal-filling glue. Clean the broken surfaces, apply the glue, align and stick them together, and let them dry thoroughly in a dry and well-ventilated area. After sticking, you can apply moderate pressure with a heavy object. If using AB glue or metal-filling glue, wait 10 minutes for the glue to dry completely.
  • Reinforcement with wooden or plastic plates: Select appropriate materials based on the shape and size of the backrest. Measure the dimensions and fix them to the outside of the broken part of the backrest using screws or nails.
  • Cracks or breaks in the metal frame: If conditions permit, welding can be used for repair. Clean and sand the broken area before welding, then sand the weld points and apply anti-rust treatment after welding. This method requires professional tools and skills and is relatively difficult to perform.
• Collapsed padding: If the backrest has lost support due to collapsed internal foam, carefully open the outer cover, cut and replace the new padding according to the original shape.

Reinforcement with connecting plates (suitable for broken metal frames): After the glue has dried, position the connecting plate and mark the hole locations with a marker pen. Two holes are needed on each side of the break to distribute the pressure. Use a cordless drill or soldering iron to make the holes. Tighten the screws on the connecting plate. If the other side is not measured correctly, secure it with stainless steel straps and tighten them with pliers. Also, tighten the stainless steel straps on the side of the break, and finally, reinstall the accessories. For aesthetics, you can cover the repaired area with carbon fiber stickers.

Other methods: Buy a 'fabric chair cover' to put on, but be careful not to lean too hard against it; weave a net with ropes on it; if there is a place that makes 'wicker chairs', you can take it there for weaving.
