Curious about how this performs in practice? Join us for a hands-on look at the Chair Seat and Back Durability Tester in action. In this video, we demonstrate BIFMA-standard fatigue testing on office chairs, showing how the machine applies precise force and displacement to seat and backrest. You'll see the pneumatic closed-loop control system at work, real-time force-time curves on the touchscreen, and how the tester ensures repeatable durability results. A clear, practical walkthrough for B2B buyers and QA teams evaluating chair testing equipment.
