Seating comfort
What constitutes good seating comfort depends on the needs and
condition of each individual. Here are some general guidelines to
consider when making the settings.
Choose a seat cushion with care. In addition to comfort, it affects
stability and thereby freedom of movement. Seat cushions also
have different degrees of pressure distribution.
The back support setting is a combination of angles, height and
shape. Therefore, the angular settings and height of the back support
may also need to be fine-tuned when adjusting the back upholstery.
Back angle
The back angle may need to be adjusted when setting the back
upholstery shape.
Contact your prescriber.
Seat cushion
•
Make sure the seat depth is set correctly.
•
Place the cushion so far back on the seat that the rounded corners
go in between the back support rails.
•
Measure the appropriate length for the seat cushion, and cut it
according to the instructions provided.
•
For a more contoured seat cushion, it can be supplemented with
a comfort wedge, which is placed in the pocket on the underside
of the seat cushion.
Back cover
•
Slacken all back straps, but make sure the Velcro straps still lock
against each other.
•
Position the back cover so that it covers the upper edge of the back
rails and forms a crease between the seat and back support so that
the user can “sit” properly on the seat.
Back upholstery
Adjustment of the back upholstery is done with the user sitting in the
wheelchair.
•
Make sure the user sits as far back as possible on the seat.
•
Support the pelvis by tightening the strap placed just below
the trunk.
•
Then adjust the upper strap so that the user gets support and
balance in the upper body.
•
The other straps are adjusted to leave space for the seat and follow
the natural rounding of the back.
Consider the risk of tipping.
Always check the setting of the anti-tip guard.
Do not over-tighten the top straps as this affects the folding of
the cross, i.e. the seat posts lock against the frame.
