Seat height adjustment
To raise the seat, stand up, lift the right lever upwards, and the seat will begin to rise. Then release the lever to lock the seat at the desired height.
To lower the seat, remain seated, lift the right lever upwards, and the seat will begin to lower. Then release the lever to lock the seat at the desired height.
Synchronized backrest and seat tilt adjustment
The mechanism is activated by lifting the left lever upwards. Then press your back against the backrest to achieve the desired tilt angle. Next, push the lever down to lock the mechanism and set the chair in the selected position. If the mechanism is not locked, the chair will allow free rocking.
The additional Antishock system prevents the backrest from striking the user’s back. To release the Antishock system, press your back against the backrest and then lean forward.
Tension adjustment
Turning the crank backwards decreases the resistance of the backrest and seat, making the chair suitable for users with lower body weight.
Turning the crank forwards increases the resistance of the backrest and seat, adjusting the chair for users with higher body weight.
Seat depth adjustment
To set the seat position, pull the left lever under the seat upwards (with the backrest tilt mechanism locked). While holding the lever, move the seat to the desired position. Then release the lever. The seat will lock in its current position.
Seat tilt adjustment
Lifting the rear right lever allows an additional forward seat tilt of 5°. Lowering the lever returns the seat to its neutral position.
The seat can be unlocked by pushing the lever downward, allowing free-floating movement.
Backrest height adjustment
Up&down system* – The backrest height is adjusted by pulling the backrest upward to the desired position. The backrest should lock into the appropriate notch. To lower the backrest, pull it all the way up to release the mechanism, then move it down.
Button-controlled adjustment* – The backrest height is adjusted by pressing the right button on the backrest while simultaneously lifting or lowering the backrest to the desired position, then releasing the button.
*Available depending on the chair model (or may not be available at all).
