Seat comfort
Good seating comfort depends on the needs and possi-
bilities available to each individual. The following general
guidelines here show what to consider when settings are
made.
Select a seat cushion with care. Aside from comfort, it has
an impact on stability and thereby freedom of movement.
Seat cushions also have different pressure distribution
Backrest cover
•
Loosen all back straps, but make sure that the Velcro is
still stuck together.
•
Place the backrest cover so that it covers the upper edge
of the back rails and forms a crease between the seat
and the backrest allowing the user to properly sit in on
the seat.
Seat cushion
•
Make sure that the correct seat depth is set.
•
Position the cushion as far back on the seat so that the
rounded corners end up between the back rails.
•
Measure a suitable seat cushion length and cut it accor-
ding to supplied instructions.
•
A more contoured seat cushion can be obtained by
using a comfort wedge which is placed in the cushion
cover's pocket under the seat cushion.
Backrest upholstery
The backrest upholstery is adjusted with the user sitting in
the wheelchair.
•
Make sure the user is sitting as far back in the seat as
possible.
•
Support the pelvis by tightening the strap found just
below the lumbar region.
•
Then adjust the upper strap to provide the user with
upper body support and balance.
•
The other straps are adjusted to provide space for the
user's posterior and follow the back's natural curvature.
Backrest angle
The backrest angle may need to be adjusted when
adjusting the shape of the backrest upholstery.
Contact your dealer or your Technical Aids Centre.

qualities.
The backrest setting is a combination of angles, height
and shape. This is why the angle settings and height for
the backrest may need to be adjusted when the backrest
cover is being adjusted.

Risk of tipping: Always check the setting of the
the anti-tips.
Do not overtighten the upper straps as this can
prevent the cross-brace from unfolding properly,
i.e. the seat-frame tubes do not sit flush in the
sideframes.
