TRU-Comfort

The TRU-Comfort cushion is a unique seatback that is
available for user comfort and positioning needs. Figure 13
provides information on the removable and adjustable TRU-
Comfort components. Use these diagrams to familiarize
yourself with the function and location of each component
before using the TRU-Comfort cushion. See figures 13 and 14
to identify which seatback is on your power chair.

Installation and Use

The TRU-Comfort consists of a seatback cushion, lumbar
support, lateral supports, lateral wings, and/ or thoracic
supports that can be placed as needed for user comfort and
positioning. They may be attached to the seatback either
with reusable hook and loop fasteners or hardware, or they
may be incorporated inside the seatback cushion.
To place the TRU-Comfort positioning components on
the chair:
1. Position the lumbar and thoracic support(s) as needed
for user comfort and positioning flat side down and push
onto the seatback. Position the lateral supports and
lateral wings as needed and attach with hardware. See
figure 13.
2. Position the seatback cushion so that the reusable hook
and loop fastener straps face the seatback. Place the
cushion over any lumbar, lateral, and thoracic support(s).
Secure the cushion to the seatback by sliding the two (2)
long loop fastener straps through the anchor hooks and
pressing the two (2) short hook fastener straps against
the longer straps. See figure 13 or 14.

Extreme temperatures can affect the temperature of
your cushion components and may cause skin irritation.
