Chair Set-up
Importance of Chair Set-up
The suitability and effectiveness of these
features are dependent on correct chair set
up. Correct chair set up is dependent on three
key elements: seat depth, seat width and seat
to floor/footrest height.
Seat Depth
Seat depth and width must be set up to suit the
client once the chair has been delivered.
Seat to Footplate Height
Seat to footplate height can be adjusted to suit
the client and is likely to be adjusted regularly.
Seat to Floor Height
Seat to floor height will have been measured
during the initial seating assessment and
the SmartSeat chair will have been factory
assembled to these measurements but can be
adjusted by a technician in the field.
Seat Depth
It is important to set seat depth correctly in
order to prevent ‘sacral sitting’ and to achieve
the best distribution of weight between the
client and the chair. Sacral sitting occurs when
the pelvis tilts backwards so that the lower
back (sacrum), as well as the bottom, is resting
on the seat cushion. The sacral area can be
susceptible to pressure problems. Sacral
sitting will occur if the seat depth is too long.
If the seat depth is too short then the client’s
SAFETY NOTE
Seat depth should not be adjusted when a client is sat in the chair or
when the chair is tilted backwards.
Seat Too Short;
Increase in pressure
beneath the bottom.
Seat Too Long;
Increased pressure on
bottom, sacrum and
shoulders.
