CUSHION ADJUSTABILITY
Fluid and Air Adjustability
The J3 Cushion offers volume adjustability to accommodate for
users needs through four models, the "Factory Filled" or the "Field
Variable" model.
The determination of Air Single or Air Dual Models is made by
your clinician during evaluation. The inserts should only be
changed at the direction of your clinician.
The fluid field variable insert has the ability to adjust to the user's
need over time. Your supplier will be involved in the adjustment
once it is determined to be needed for better clinical efficacy.
Adjusting through the "Field Variable Volume" J3 Cushion
The Field Variable version of the J3 Cushion allows the
appropriate healthcare provider to apply a specified amount of
fluid at the time of prescription and to modify the amount of fluid if
needs change through the use of discreet Fluid Supplement Pads.
This method of adjustment is useful where there is no concern of
unqualified fluid adjustments occurring after prescription.
Adjusting through the Air Insert
The air insert version of the JAY J3 Cushion can be adjusted at
any time through the use of the hand pump (provided) and
release valve on the Air Insert.
The Field Variable Fluid Pad comes standard with 2 Fluid
Supplement Pads and has a Blue Urethane Cover to
differentiate it versus the standard grey urethane on the
Factory Filled Fluid Pad. This color difference identifies
that the Blue Fluid Pad comes underfilled in comparison to
the Factory Filled Pad, and has 4 velcro attachment points
to attach the standard Fluid Supplement pads to handle
obliquities, and overfills. To determine how to use the Fluid
Supplement Pads, please reference the "Fitting a Pressure
Distributing Cushion" section.

CUSHION
Using Fluid Supplements pads
Fluid Supplement Pads are to be only used with the Field
Variable Fluid Pad. To determine if you have a Field Variable
Fluid Pad, unzip the cushion cover, and look at the pad in the
Pelvic Loading Area. If the pad has blue outer cover, it is a Field
Variable Fluid pad and designed to work with Fluid Supplement
Pads.
An authorized clinician or therapist should use Fluid Supplement
Pads by attaching or removing to the Fluid Pad Velcro
Attachment points located between the folds on the upper Fluid
Pad surface to increase or decrease the amount of fluid needed.
Fitting the cushion
Select a cushion to match your hip width when in the seated
position. The cushion length should extend to within 1" -
2" (2.5cm -5cm) from the back of the knees. Place the cushion
to the back of the wheelchair with the material identification tags
and pressure relieving pad 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 insert in the pelvic loading
area of the cushion. 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.
Use the cushion indexing notches located in the rear of the
foam base to ensure proper alignment of the cushion to the
backrest. Misalignment of the insert and pelvic loading area
could lead to injury and skin breakdown.
Avoid using the cushion on overly stretched seat upholstery.
Stretched upholstery does not provide adequate support for the
cushion and improper positioning may result. Replace stretched
upholstery or purchase the Jay Adjustable Solid Seat.
Reference the Air Insert Owner's Manual Supplement for proper
fitting and set-up instructions.
