ENGL ISH
GROWING THE CUSHION WITH A DEPTH
ADJUSTABLE BACK FITTED
Begin by seating the client forward on the Cushion, with
the Back adjusted forward of the upright posts.
As the client grows, adjust the Back Support backwards
towards the posts. This allows the user to be seated
further back in the well and maintain proper seat depth.
Pre-Ischial Shelf Extenders can be added to position the
anti-thrust shelf where needed and optimize leg support.
The ischial tuberosities, or seat bones, should be located
approximately 1" to 2" (2.5 to 5 cm) behind the antithrust
shelf. One Shelf Extender is included with the cushion,
others can be ordered as needed.
The Cushion "grows" by 1" (2.5 cm) every time a Shelf
Extender is added.*
When the Back has been adjusted as far back as
possible, the Cushion can be moved forward for
additional growth.
The front edge of the GS Cushion can extend up to 2"-
(5 cm), unsupported beyond the front of the seat base
without affecting performance.
The use of a JAY Adjustable Solid Seat with Lip Option
is highly recommended when "growing" the GS Cushion
in this way. It allows you to easily relocate the cushion in
its desired position if you remove it from the wheelchair.

GROWING THE CUSHION WITH A FIXED BACK
FITTED
Notch the rear corners of the base enough to allow the
Cushion to slide between the upright posts of the wheelchair
and to establish proper seat depth.
Proper seat depth equates to approximately one to two
finger widths between the back of knee and front of cushion.
As the client grows, adjust the Cushion forward ensuring
that the buttocks sit in the carved-out portion of the cushion.
Remember to maintain the desired distance between the
back of the knee and the front of the Cushion.
When the Cushion is adjusted forward by 1" (2.5 cm), or
more*, add a Pre-ischial Shelf Extender to the cushion,
(included), this will maintain the anti-thrust properties of the
GS Cushion.
The front edge of the GS Cushion can extend up to 2"
unsupported beyond the front of the seat base without
affecting performance.
The use of a JAY Adjustable Solid Seat with lip option is
highly recommended when "growing" the GS Cushion in
this way. It allows you to easily relocate the cushion in its
desired position, if you remove it from the wheelchair.
Growth in width of the Cushion is accomplished through the
use of accessories. Lateral Pelvic Supports, (hip guides),
can be adjusted inward 1" (2.5 cm) on either side and then
moved out later for growth at the rear of the Cushion.
Lateral Thigh Supports (abductors) can be adjusted inward
1" on either side and then moved out later for growth at the
front of the Cushion.
* If using the GS Pressure Relief Pad, use of only one Shelf
Extender is recommended.
NOTE:
The JAY GS Cushion may be used with different backs
depending on the level of disability. For moderately involved
clients, try the JAY J3 Back. For more severely involved
clients, try the JAY Fit Back. Growth in the seating system is
ossible with all of the above products when combined with
the GS Cushion.
