Office Chair Backrest Repeated Pull Fatigue Testing Machine

Short Description:

This Office Chair Backrest Repetition Testing Machine (Rear-pull Type) is designed to evaluate the durability and structural integrity of office chair backrests. It simulates repeated rearward pulling forces—mimicking real-life leaning pressure—through a controlled rear-pull mechanism to test the backrest frame, adjustment mechanisms, and mounting points for fatigue resistance, compliance with BIFMA standards, and long-term safety performance.
