Chair Backward Durability Tester is to evaluate the ability of the chair back to withstand the fatigue stress and wear that occur as the result of user exerting backward pressure on the chair.

Testing methods:fix chair and impose a poise of 225pounds on the seat surface and keep the tilt mechanism reciprocating movement within its front and back limits for 300000 times at a speed of 10-30cpm.

Standard : ANSI/BIFMA X5.1-2017 , BS EN 1335-1-2020
