The tilt mechanism of the seat;
The height adjustment;
The durability of the frame;
The control buttons;
The locking systems;
The forward and sideways movements;
The resistance to tipping and falling over tested.
Thanks to these extensive tests, the chairs are certified for intensive 24/7 use by persons weighing up to 150 kg, for example in control rooms of emergency services, security centres, air traffic control posts and railway control rooms.
