1. Synchronous seat/backrest inclination adjustment
2. Locking in many positions
3. Number of levers – 2
4. Tension adjustment by bottom handwheel
5. Seat inclination +13°, backrest 19°
6. Antishock – protection from uncontrolled backrest movement

To raise the seat, get up from the chair, raise the right lever upwards and the seat will begin to raise, then release the lever to lock the seat at the desired height.

To lower the seat, the right lever should be raised in the sitting position, the seat will begain the lower, than release the lewer to lock the seat at the desired height.

Activate the mechanism by lifting the left lever upwards. With the mechanism released, the back pressure should be applied to the backrest to achieve the desired angle of backrest and seat.

Then turn the lever down to lock the mechanism and set the chair in a certain position. If the mechanism is not blocked on the chair, you can rock freely.

Turning the handwheel to the left, the resistance of the backrest and the seat decrease, adapting the chair to people with lower body weight.

Turning the handwheel to the right increase the resistance of the backrest and seat, adapting the chair to people with higher body weight.
