Office Chair Diagram Assembly: Tools & Common Problems

The primary tool required for assembling an office chair is an Allen wrench (M), with common issues involving assembly precautions, maintenance, and stability and safety concerns in the market.

Tools Required for Assembly

Assembling an office chair primarily relies on an Allen wrench (M), which plays a role in multiple assembly steps. For example, use Allen bolts (I) and (H) to secure the seat plate (D) to the seat (B); use Allen bolt (J) to attach the backrest (A) to the seat (B); use Allen bolt (K) to fix the armrests (C) to the backrest and seat, etc.
