SEAT HEIGHT ADJUSTMENT 

Adjust the seat height with your upper 
and lower leg angled at 90°  
to 100°. This position will result in  
the least possible pressure on the 
upper legs which allows for a better 
blood circulation.

 

SEAT DEPTH ADJUSTMENT

Adjust the seat depth to a space 
approximately the size of a fist 
between the seat and the backs of the 
knees. This position will result in the 
least possible pressure on the upper 
legs which allows for a better blood 
circulation.

Push the button to move the 

seat forward or backward 

for a longer or shorter seat 

surface.

LUMBAR SUPPORT 
ADJUSTMENT

Adjust in height to where the lumbar 
support is on the same level as your 
belt (just slightly below the hollow of 
your back and just above your pelvis). 
This ensures the right support of the 
lower back.

Move the lumbar support on 

the rear of the backrest up 

or down for the right lumbar 

support.

AUTOFIT SYNCHRONOUS MECHANISM 

The use of the autifit synchronous mechanism stimulates sitting in a dynamic way. It 
prevents static strain and helps to prevent complaints which are caused by sitting for long 
periods of time. Therefore we recommend always setting the chair in active mode. 
The autofit synchronous mechanism can be set in three dynamic modes.

S: small rearward movement 
M: medium rearward movement 
L: large rearward movement

Starting point: Back is fi xed in upright position (lever fully pull out)

• 

 Activating dynamic mode S:  
Push the lever one position inside

• 

Activating dynamic mode M:  
Push the lever two positions inside

• 

Activating dynamic mode L:  
Push the lever three positions inside
