chair.
8a. Seat Depth Adjustment
Appropriate seat depth is critical to the
performance of the chair and the user’s
postural stability. To adjust seat depth:
1. Locate the lever (A) at the back and
left-hand side under the chair.
2. Twist lever down and pull/push the
seat frame (B) on right-hand side until
seat depth is in desired position.
3. Release the lever and pull the handle
until the seat “clicks” positively into
position.
•
Never adjust the seat depth when
the user is in the chair or when the
chair is reclined.
8. Seat Depth
It is critical to set seat depth correctly in order to prevent ‘sacral sitting’ and to achieve
the best distribution of weight between the user and the chair.
•
Sacral sitting occurs when the pelvis tilts backwards. The sacral area can be
susceptible to pressure problems. Sacral sitting will occur if the seat depth is
set too long. If the seat depth is too short then the area over which body weight
is distributed may be reduced, which can increase the risk of pressure injury.
•
Seat depth should be set with the user’s pelvis positioned firmly at the back of
the seat cushion so that their lower back and lumbar is supported by the back
cushion. There should be a two or three finger gap between the back of the
user’s knee and the front of the seat cushion for comfort.
•
If the individual already has a chair or wheelchair with the correct seat depth,
measure this size and use it as a starting point for setting the SmartSeatPro
