CUSHION INSTALLATION
Select a cushion size which corresponds to your
hip width when you are seated. The cushion length
should extend 3-5 cm from the back of the knees.
Place the cushion as far back as possible in the
wheelchair. The curved rear edge and the cut-
out corners should be as close as possible to the
wheelchair back. In order to achieve the lowest
possible seated pressure, the footrests should be set
at a low position so that your thighs rest comfortably
on the front part of the cushion. (Setting the footrests
correctly can reduce pressure on certain points.)
When you are seated on the Jay Xtreme Active
cushion, your ischium should be centralised on the
fluid pad. If the cushion is not positioned correctly,
this can lead to bottoming out and tissue damage. If
you have oblique posture, position the cushion slightly
further forward in the chair, so that you are not sitting
on the front foam part of the cushion. (If you have
extreme oblique posture, we would recommend the
JAY J2® and JAY J3 cushions.) In addition, if your
backrest is a sling-type, then this should be replaced.
Instead of this, you could use a JAY J3 backrest.
A solid backrest positions the hips correctly and
supports the trunk, so that you are sitting less on your
sacrum, i.e. your pelvis is tilted backwards.
INSTALLATION OF DIFFERENT FLUID PADS
The Xtreme Active cushion can be ordered with
two different fluid pads: one with a larger amount of
fluid and another containing less fluid (optimized for
lightweight).
The fluid pads are colour coded and need to be
installed onto the inner cover according to the Velcro®
loop and hook colours.

NOTE:
• The inner and outer covers of Xtreme Active do not
have to be exchanged when you switch from one
fluid type to the other. But the bases of the Xtreme
Active are fluid-dependent.
• Always attach black hook on fluid pads to black loop
on inner cover and grey hook on fluid pads to grey
loop on inner covers.
CHECKING FOR BOTTOMING OUT
Bottoming out occurs on an Xtreme Active Cushion
when you displace the fluid out from underneath your
seat bones, which leaves you sitting on the foam base. It
sometimes occurs on very thin individuals, people using
recliner wheelchairs, people who slouch when sitting or if
using a cushion that is too wide.
When bottoming out occurs, increased pressure is
loaded onto the ischials and coccyx increasing the risk
for skin breakdown.
To test for bottoming out, sit for at least 2 minutes on the
Jay Xtreme Active cushion without the cover. Transfer up
and off the cushion (or have someone help you transfer),
trying not to disturb the fluid underneath you. Push down
in the depressions on the pad where your ischials (seat
bones) and coccyx (tailbone) were. You should have to
push through at least 1/2" (1cm) of fluid before you feel
the firm cushion base below.
If the cushion is properly positioned and the footrests
are properly adjusted, and there is not at least the
minimum 1/2" (1cm) of fluid, the cushion is bottoming out
and should not be used. (If you have a relatively recent
injury, a fluid layer of 2 cm is recommended, as this can
possibly lead to post-traumatic atrophy). If bottoming out
occurs, you might need an overfilled fluid pad. You can
obtain an overfilled fluid pad from your dealer or from
Sunrise Medical customer service.
WARNING
When bottoming-out occurs, increased pressure is
placed onto the ischium and coccyx increasing the risk of
skin breakdown. Immediately discontinue use of the pad.
