The Spinalus-2 seating sys-

system from 40 to 55 cm in
seat width. In steps of 5 cm.
When changing from one

cushions there is webbings
that can be adjusted for good comfort, and adjustable for var-
ies seat widths. The upper part of the backrest, can be angled

the back moves down at the same time as it is angled back-
wards. It is a sliding function that compensate for change of
position and reduce the displacement.
The armrests follow the back and also have a dynamic move-
ment that ensures that they are held parallel when the back is
angled. The armrests are available in many different lengths
and can be adjusted steplessly back and forth.
