19 Seat system
Avoid falling into the seating and back
padding/back shell as it significantly increases
the risk of an adjustment, falling down or
defects.
The seat system generally either comprises a
spring suspended Body Contour seat
upholstery or an open belt system.
With a seating system from Body Contour
seat upholstery, there is no adjustment
option. The Body Contour seat upholstery has
a springing effect and when seating.,
automatically forms a slack.

The open belt system can be subsequently
adjusted. Using the fleece hook-and-loop
straps, the slack in the seating surface can be
changed so that it suits your seat cushion
system. In doing so, the seat tension should
not have too much slack to avoid touching the
frame cross tubes.
