BACKREST
The HP2TM backrest line was designed with high performance and precision in
mind. Characterised by a rigid shell that encompasses the user’s back to
provide overall lateral and central support, this backrest was created for
persons with significant postural asymmetries.
Three models are available:
A contour model designed to
provide overall back support.
A profiled model designed for
active users, which permits upper
body freedom of movement and
provides greater ease of
propulsion.
A sport model designed for
rigid structure chairs. It provides
enhanced lumbar support and
greater freedom of movement.

RECOMMENDATIONS
To ensure your backrest provides optimal protection and comfort and
to extend your product lifespan, the following precautions should be
applied.
•Before use, it is important to verify the quality and condition of the
backrest components, please refer to Maintenance guide in section
Maintenance, page 19.
•Physipro Inc. backrest are reserved exclusively for use on mobility aids
(manual or power wheelchairs).
•Always install backrest with the provided mounting hardware.
•Never push or lift wheelchair with backrest, doing so may cause the
backrest to detach from the wheelchair and can result in injury or
damage.
•Before installation, make sure the backrest is compatible with the
wheelchair’s dimensions.
•Never place a towel, a blanket, a folded bed sheet or any other
material between the user and the backrest, this will diminish the
backrest efficiency and increase the risk of developing skin lesions.
•It is preferable to wear clothes made of cotton, that are not too tight and do
not have seams on pressure points.
•Before use, let the backrest get to room temperature to limit
discomfort caused by excessively hot or cold surfaces.
•Remove any foreign object (crumbs, debris, tubing, etc.) from
backrest surface.
•Clean on a regular basis and visually inspect all components of the
cushion periodically.
HP2 Backrest
It is recommended to consult your therapist in the month following the
installation of a new cushion to make sure it is efficient.

WARNINGS
Consult a healthcare professional: Physipro Inc. recommends that a health
care professional such as a doctor or therapist, experienced in seating
and positioning, be consulted to determine, and install the required seating
system and make any necessary adjustments.
Center of gravity: Installing a backrest on a wheelchair may affect the center
of gravity of the wheelchair and may cause the wheelchair to tip backwards,
potentially resulting in injury. To ensure optimal stability of your wheelchair after
the addition of a new backrest, always assess for the potential need for anti-tippers
or amputee axle adapter brackets to be added or adjusted to increase stability.
Backrest dimensions: The dimensions of the backrest must be adapted to
the user and the wheelchair, if not, the backrest’s benefits will be reduced or
eliminated.
Backrest and cover compatibility: The backrest cover must be well-fitted and
used as directed in this manual to prevent the formation of skin lesions. An
oversized or undersized cover will reduce or eliminate the effectiveness of the
backrest and can reduce stability.
Environment: Avoid exposing foam to fluids or moisture for prolonged periods.
Avoid exposing the backrest to extreme cold or heat. Never place backrest near
open flame.
Instability/Fall risk: Never place other products or materials (except those
specified in this manual) between the user and the backrest or underneath the
backrest, doing so, will cause instability and increase the risk of injury from a fall.
Positioning of backrest: Always refer to the orientation indicators, located on
the backrest and the cover, to properly position backrest on wheelchair. Proper
positioning is essential to ensure maximum comfort and pressure relief.
Skin inspection: Backrest should be tested before prolonged use. To avoid the
appearance of skin redness due to pressure points, Physipro Inc. recommends
shifting your weight as frequently as possible and performing a pressure relief
technique at least once every two (2) hours. You should regularly check (at least
once a day) for skin redness especially around bony prominences. If skin redness
or discoloration develops, discontinue use of the cushion. If discoloration does
not disappear within thirty (30) minutes consult a Healthcare professional
immediately. Be aware that no backrest can substitute the need for proper skin
hygiene, a balanced diet and frequent position changes.
Transport: Crash tests have not been conducted on these products and even if
the mobility aid in which it is installed has obtained the ISO-717619, it will not be
maintained.
