To lower the seat, while sitting, lift the right lever upward, and the seat will begin to lower. Then release the lever to lock the seat at the desired height.
Synchronized adjustment of the backrest and seat tilt angle
Activate the mechanism by turning the left knob forward. With the mechanism released, lean your back against the backrest to achieve the desired tilt angle of both the backrest and the seat. Then turn the knob backward to lock the mechanism and set the chair in the chosen position. If the mechanism is not locked, the chair can be freely rocked.
The additional Antishock system prevents the backrest from striking the user's back. To unlock the Antishock system, press your back against the backrest and then bend forward.
Adjustment of backrest and seat recline resistance
Turning the knob backward decreases the resistance of the backrest and seat, making the chair suitable for users with lower body weight.
Turning the knob forward increases the resistance of the backrest and seat, adjusting the chair for users with higher body weight.
Seat depth adjustment
Pull the left lever under the seat upward while the backrest movement mechanism is locked. While holding the lever, set the seat in the desired position. Then release the lever. The seat will lock in the current position.
Seat angle adjustment
Forward tilting of the seat is achieved using the additional left rear lever.
