This machine is suitable for the comprehensive test of office chair armrest and backrest, for the test of the strength of office chair armrest and backrest. The armrest of arm strength test is mainly used for testing all kinds of seats being in good condition after the pressure, to simulate the during normal use and habitual misuse, a single or repetitive loading conditions of strength or ability test, is used to test the product in May encounter heavy load conditions the intensity with which assess the armrest of office chairs along the horizontal direction and vertical direction under compressive capacity; The backrest strength test is used to assess the chair's resistance to pressure, simulating the pressure applied to the back of the chair when the user presses back.
