This chair seat and back combined test machine is designed for evaluating the durability, structural strength, and mechanical performance of office chairs. The machine is capable of performing seat durability testing, backrest durability testing, tilt mechanism testing, and static load strength testing, providing comprehensive quality evaluation for office chairs.
By fixing the chair casters, the test machine applies controlled force, speed, and repeated movement to the chair seat and backrest. The system simulates real-life usage conditions, allowing manufacturers and testing laboratories to assess chair durability, fatigue resistance, and static load strength under specified test conditions.
