Rotary chair front stability testing machine is designed to test chair’s stability when forward movement is carried out.
Placing the testing chair in front of a working table, block its front legs with baffles, and enforce some load on chair’s seat surface. After that, give a 20N’s forward force on its load point, and see whether the sample will lean forward or not. In this way, the front stability of our chairs could be evaluated.
