QUADTRO SELECTAdjustment Guide Rev. 4/19 Print 4/19
Please refer to the Operation Manual for other safety
information regarding the QUADTRO SELECT cushion.
NOTE: Before adjusting QUADTRO SELECT for an asymmetry, you MUST perform a hand check to adjust the air inflation level to
proper cushion inflation setting
as detailed on the
reverse side of this document.

cushion for positioning
1. Make sure the ISOFLO Memory Control is open
(press green knob in). FIGURE 1
2. Have the individual sit on the cushion in the most
upright and midline posture that they can achieve.
FIGURE 9
3. Close the ISOFLO (press red knob in). This will
help hold the pelvis in the best posture that is
achievable by that individual and prevent further
progression into asymmetry. FIGURE 3
4. Perform a hand check and make sure there is a
minimum of ½ - 1” of air between the lowest ischial
tuberosity and the seat surface. FIGURE 8 & 10

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
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
