CHECKING FOR BOTTOMING OUT ON THE J2 PLUS CUSHION
Bottoming out occurs on a J2 Plus 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 bony individuals, people using recliner wheelchairs, people who slouch
when sitting, people who move a lot, shifting the fluid, or if using a cushion that is
too wide.
When bottoming out occurs, increased pressure is placed onto the ischials and coccyx
increasing the risk for skin breakdown.
To check for bottoming out, sit on the cushion without the cover for a minimum of
two minutes. 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 bottoming out occurs discontinue use of this cushion and contact your healthcare
professional. If further assistance is necessary, contact your Sunrise Medical Supplier.
FITTING THE J2 PLUS CUSHION
A healthcare professional should ideally fit a pressure-distributing cushion to you.
Improper cushion fit may be detrimental to the performance of a pressure-distributing
cushion and its support of the body.
Place the cushion to the back of the wheelchair with the material identification tags
and fluid pad or the foam inserts toward the rear. When fit correctly, your hips should
be to the back of the chair. Your ischials (seat bones) should be centered on the Jay
Flow™ fluid pad or on the foam inserts in the seat well of the cushion. Your hip bones
(trochanters) should be supported by the foam along the lateral (outside) borders of
the well. Proper footrest adjustment may enhance sitting comfort and help lower peak
sitting pressures. Adjust the footrests so your legs rest firmly but comfortably on the
cushion.
NOTE– We recommend using a J2 Plus Solid Seat Insert. It will optimize the performance of your
J2 Plus Cushion, help provide better positioning and increase the life of the cushion.

ASSEMBLING THE SEAT WELL
(Figure 1)
To Insert Well Foam
Stack the 3 layers of foam (foam well inserts) with
smallest toward the bottom and largest on top. Be sure
the beveled edges are in the same direction as the well
cutout forming a single, angled edge. Fold all 3 layers
of foam and insert into pocket until they fit fully into
the well. Allow the foam to unfold so that the rounded
corners fit snugly into the back of the pocket.
(Figure 2)
To Insert Fluid Pad
Fold fluid pad in half so that Velcro® is on the outside.
Slide Fluid Pad into pocket, making certain that the
back of the pad is toward the opening of the envelope.
The word "Back" is printed on a tag on the Fluid Pad.
Position the pad to the correct side of the pocket and
unfold. Be certain that Velcro on the Fluid Pad mates
to Velcro in the urethane pocket.
(Figures 3 & 4)
To Reseal the Urethane Envelope
Position urethane envelope with dark gray side up.
Tuck dark gray layer between insert foam and well
pocket. Folding left and right sides in at 45° angles
will form a smooth flap (Fig. 3). Fold the light gray
flap around entire cushion thickness and fasten by
aligning 3 Velcro strips (Fig. 4).
