Seat height adjustment with the right lever
To raise the seat, get up from the chair, lift the right lever up, the seat will start to rise, then release the lever to lock the seat at the desired height.
To lower the seat, in a sitting position, lift the right lever up, the seat will begin to lower, then release the lever to lock the seat at the desired height.
Synchronized angle adjustment of the backrest and seat with the left knob
The mechanism is activated by moving the left knob backwards. With the mechanism unscrewed, press your back against the backrest to obtain the desired angle of inclination. Then, turn the knob forward to lock the mechanism and set the chair in the desired position. If the mechanism is not locked, you will be able to rock freely in the chair.
An additional Anti-Shock system prevents the backrest from hitting the seated person's back. To unlock the Anti-Shock system, press your back against the backrest and then lean forward.
The intensity is regulated by a knob
By turning the right knob forward, the resistance force of the backrest and seat is reduced, thus adjusting the chair to people with a lower body weight.
Tightening the knob backwards increases the resistance of the backrest and seat, adjusting the chair to people with greater body weight.
Seat angle adjustment with the right lever
Raising the right lever forward allows the seat to tilt an additional 5º forwards.
Unlocking the seat is possible after lowering the lever (free swimming).
Backrest height adjustment (depending on the chair model)
Up & Down system – the backrest high is adjusted by pulling the backrest up to the required height. The backrest should stop at the appropriate latch, to lower if the backrest should be pulled all the way up and the lowered down.
Adjustment by means of a button.
