Check by keeping 150 kg objet on chair whether it is capable or not

For Stress Testing
Check by keeping the objets weighing from 150 kg to peak weight till the chair is capable

Load Test:  Testing upper limit for normal use.  Place weight on the chair that is distributed to mimic a human sitting on it.  The average pressure on the chair throughout the entire weight distribution should begin at 50 kg (110 lbs).  In one minute intervals, increase the weight by 5kg until you reach 150 kg (330 lbs).

Stress Test:  Testing upper limit beyond normal use.  Place weight on the chair that is distributed to mimic a human sitting on it.  The average pressure on the chair throughout the entire weight distribution should begin at 125 kg (275 lbs).  In one minute intervals, increase the weight by 5kg until you reach 200 kg (440 lbs).
