to
-
floor heights are
approximate to 6.5 mm due to tire wear and air pressure.
Measuring Front Seat-to-Floor Height
Front Seat
-
to
-
Floor Height: Measure the distance between the front of the seat upholstery
and the ground/floor.

Changing Seat-to-Floor Height
W A R N I N G
The seat height, seat depth, back angle, seating system, size/position of the
rear wheels, size/position of the front castors, seating options (e.g. headrest,
back bag, …) as well as the user condition directly relate to the stability of the
wheelchair. Any change to one or any combination of the nine may cause the
wheelchair to decrease in stability. Refer table on page 6.
Always check castor vertical axis is to 90° +/-1° from the ground.
NOTE: For this procedure, refer to the table to determine adjustment(s) necessary to
achieve desired front seat to floor height.
