Seat Belt should be firmly tight-
ened to help position the pelvis
back in the seat in a neutral
position.
The feet should rest firmly on
the footbed to provide support
for lower extremities
Head Rest should provide enough
support to enable the child to bal-
ance, laterally as well as fore and
aft, without preventing the child’s
ability to shift position to engage in
functional activities.
The seat back cushion should provide
enough support to maintain proper
alignment while not impeding the
ability for the child to be actively en-
gaged with his or her environment.
