Product test:
In accordance with the real usage scenario, the chair is securely fastened to formwork plywood using screws, with a 1.5-meter-long LVL beam positioned on top. Regardless of its height adjustment, the chair maintains a consistent height. Under full-open conditions, applying pressure of up to 94kg results in a deformation of 5mm, while under full-close conditions, the same pressure causes a 5mm deformation. Remarkably, even when subjected to a pressure of 230kg, the structure did not collapse but underwent significant deformation. Upon pressure removal, approximately 95% of its original shape was restored.
