cushion
ination and adjustment guide
The QUADTRO SELECT has four compartments of air cells. When the ISOFLO
®
Memory Control is open, the air ows freely between the compartments. When the ISOFLO is closed, the air
is “locked” within each compartment. The ination level of each compartment can be separately adjusted. This allows you to correct or accommodate side-to-side and/or anterior-posterior
asymmetries of the pelvis and upper legs. NOTE: Before adjusting the cushion for an asymmetry, you MUST adjust the air ination level to the proper cushion ination setting as outlined below.
After overinating the cushion, perform a hand check to
adjust to the proper cushion ination setting:
QUADTRO SELECT setup Hand check results
Inate and adjust the ROHO QUADTRO
SELECT cushion for a new individual.
1. Place the QUADTRO SELECT cushion in the
wheelchair with the air cells facing up and the
non-skid surface of the cover facing down.
2. Before inating, you must
open the ISOFLO Memory
Control so that all of the air
cells will inate. Push the
ISOFLO green knob toward
the unlocked position.
3. Slide the rubber nozzle of the hand pump over the
ination valve. Pinch the nozzle, turn to open the
ination valve, and overinate the air cells.
QUADTRO SELECT adjustment
Check the ination level daily
by performing a hand check.
Re-adjust the ination level only as
needed (typically every 3-4 months).
Proper cushion ination setting
½” – 1” (1.5 cm – 2.5 cm)
— If you can slightly move your ngertips: the cushion
is at the Proper Cushion Ination Setting (½” - 1” air
between the lowest bony prominence and the seat
surface) and no further adjustment is needed.
— If you can easily move your ngertips: there is too
much air between the lowest bony part prominence
and the seat surface. Open the ination valve and
slowly release air until you can barely move your
ngertips, then close the valve.
— If you cannot move your ngertips at all: there is
too little/no air between the lowest bony prominence
and the seat surface. Open the ination valve and
slowly add air until you can slightly move your
ngertips, then close the valve.
See reverse side for instructions on how to adjust
QUADTRO SELECT for postural asymmetries.

4. Remove the hand pump.
1. The individual should sit
in the chair in their usual
position. The cushion
should be centered
beneath the individual.
2. Perform a hand check:
a. Slide your hand between
the cushion and the
individual. Lift the leg
slightly and feel for the
lowest bony prominence,
and then lower the leg to
a sitting position.
b. Open the valve to remove
air, keeping your hand
beneath the individual’s
lowest bony prominence.
c. Release air until you
can slightly move your
ngertips. Close the valve.
