Chair product defect investigation


Manufacturing Defect: Plaintiff Side


Multi-Disciplinary Investigation of a Chair Failure


A plaintiff was leaning back on his office chair when he heard a loud snapping noise and fell backwards off the chair.  Through x-rays we were able to determine a that a torsion rod intended to provide stability to the chair back had broken.


With the opposing side’s cooperation, we performed a destructive inspection together with a metallurgical examination that revealed a manufacturing defect in the torsion rod that caused it to fail.


The plaintiff, who was a fireman, was unable to work due to his injuries.  Plaintiff received a seven figure settlement.
