In order to now 

automatically adopt the active sitting position, 

the following steps should be 

taken: 
 

 

       

► 

  

 

 

passive position 

 

 

active position 

 
To set the chair in the active position 

(see diagram) 

 
5.

 

Loosen knob 1, move it to a lower position on the dial (ie. 3), then tighten knob again to 
secure that position. 

6.

 

Now raise your chest and bring it forward, thereby bringing the trunk forward slightly and 
gently hollowing the back. Now tilt your pelvis forward. 

Tip: lean on the knees with elbows stretched 

and bring the chest bone slightly 

forward/upward; see diagram. The saddle should now come up easily. 

 
NB: 

When returning to the passive sitting position the saddle should easily go back to its 

starting position (in the passive setting). If this is not the case, or if the saddle does not 
easily return to its starting position, then readjust knob 4 to a slightly higher setting. 

 
Important: 

When re-adopting the passive position, 

first sit 

(with slightly hollowed back), 

then lean 

(do not slouch or sprawl, in other words, for this would lock the scissor 

movement of the chair). This also works as 

a reminder of the correct deportment that 

one should aim for.

  

 

Accessories: foot ring, arm rests, foot control (on request). 

 

The ErgoDynamic is a chair which encourages and promotes a more active sitting 

position, whereby back complaints can be prevented and dealt with. This altered sitting 

behaviour may possibly result in slightly aching muscles in the beginning; a period of 

adjustment is normal (physiological muscle ache).
