Seating 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

Back support cover

•

Loosen all back straps, but make sure that the Velcro is

still stuck together.

•

Place the back support cover so that it covers the upper

edge of the back rails and forms a crease between the

seat and the back support, 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. Make

sure the cushion sticks to the Velcro.

•

Measure a suitable seat cushion length and cut it ac-

cording 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.

Back support upholstery

The back support 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.
