Adjusting a ROHO
cushion for positioning
NOTE: Before adjusting QUADTRO SELECT for an asymmetry, you MUST perform a hand check to adjust the air inflation level to
reverse side of this document.
To correct a reducible (flexible) posterior
pelvic tilt (anterior-posterior asymmetry):
1. Make sure the ISOFLO Memory Control is open
(press green knob in). FIGURE 1
2. Make sure the pelvis is located at the back of the
cushion, in a neutral and upright position. FIGURE 2
3. Use your hands to create downward pressure on
both sides of the pelvis to force air to the front
quadrants and create a contour for the pelvis that
will help discourage forward migration; close the
ISOFLO (press red knob in), and then release the
pressure on the pelvis. FIGURE 3
4. Perform a hand check and make sure there is
a minimum of ½ - 1" of air between the ischial
tuberosities and the seat surface. FIGURE 4

To correct a reducible (flexible)
pelvic obliquity (lateral asymmetry):
1. Make sure the ISOFLO Memory Control is open
(press green knob in). FIGURE 1
2. Make sure the pelvis is positioned at the back of
the cushion. FIGURE 2
3. Position the pelvis in a neutral and upright position
by pressing down on the higher side of the pelvis
until the pelvis is level. FIGURE 6
This will force more air into the quadrant under
the lower side of the pelvis to help prevent it from
tilting to that side. FIGURE 7
Close the ISOFLO (press red knob in), then release
your pressure on the pelvis. FIGURE 3
4. Perform a hand check and make sure there is
a minimum of ½ - 1" of air between the ischial
tuberosity and the seat surface. FIGURE 8
