Only High quality swivel chair can withstand three test
QB/T2280-2016 Abrasion and Fatigue Test—Standard QB/T2280-2016
Under the load of 113kg, record a reciprocating cycle as one time and do reciprocating motion of the stroke.at least 762mm. whole course of one reciprocating cycle motion for 762mm stroke is more than 1.5m. The test of crossed obstacles for two thousand times and doing reciprocating cycles 98,000 times under obstacle-free conditions, totally 100,000 times for reciprocating motion of 762mm stroke, are equivalent to carrying 113kg of heavy objects and trudged more than 150 kilometers, but five casters of chair without any damage!
Impact Test-Standard QB/T2280-2016
Adjust the caster to the most vulnerable state and throwing 120kg sandbag to seat surface from the height of 152mm for 2 times. Then reduce the impact weight to 57kg, impact height to 30mm,repeated impact for 100,000 times. The casters are still very strong under 100,000 times impact test!

Drop Test-Standard QB/T2280-2016
Lift the chair to a height of 200mm, the angle between the chair legs and the ground is 10±2°, then doing free fall for 10 times but the leg of the chair must not have any damage or defects for using.
