The TESS BACK is a rigid back support system with over 30 different back and side support
combinations. These can be adjusted to support a wide variety of basic to intermediate
wheelchair users who require firm pelvis, posterior and trunk side support. It can be fitted
onto a wide range of different wheelchairs, both manual and motorised.
The TESS BACK can be adjusted in angle by 15° and in width by up to 50mm to ensure
proper fit for different users.
We recommend using the TESS BACK in conjunction
with an appropriate pressure care cushion
to promote healthy development of the
pelvis and spine in children and
to help prevent pelvis and spinal
deviations in adults.
Please enquire about our
Seat Cushions for more details.

STEP 1: ATTACHMENT TO WHEELCHAIR
To fit the TESS BACK you will need to attach
and set up the mounting clamps.
First open the clamp by undoing the bolt using
a 5mm allen key.
Fit the clamp around the back post, keep the
clasp at the back in place and fit the pin in the
front as shown. Secure it all with the bolt.
Make sure the bolt faces outwards ensuring
that the clamp with the threaded hole is on the
inside and the clamp with the smooth hole is
on the outside.
Attachment is the same for all the clamps.
Tighten bolt once position has been decided.

HEIGHT ADJUSTMENT

STEP 1: UNDO THE BOLT
STEP 2: ADJUSTING HEIGHT
NOTE:
To loosen the clamps undo the bolt slightly
with a 5mm allen key until the clamp can be
slid up or down on the back post into the
desired position.
Remember to check the height position of
the TESS BACK with the user seated in the
chair.
Always make sure to check that
there is at least a two nger / 30mm gap
between the user’s armpit (axilla) and the
top of the TESS BACK trunk side support.
The height of the backrest can be adjusted
by loosening and moving the clamps up or
down the wheelchair backpost to the desired
height.
TOOLS REQUIRED:
Correctly positioning the TESS on the wheelchair back posts is as simple as loosening and
moving the clamps.

STEP 1: LOOSENING THE NUTS
CHECK WIDTH MEASUREMENTS
Width adjustments can be done with the
user seated in the wheelchair and may be
easier with the assistance of another person.
To make adjustments first remove the
cover to access the adjustment bolts.
Loosen each nut located on the back of the
backrest, slightly. This will allow the whole
Tess Back to be adjusted narrower or wider
with the user as it is being set up.
Measure the user’s trunk width.
Measure the width between the trunk side
supports of the TESS BACK is correct for
the user’s trunk.
Place the user back in the wheelchair.
FINAL STEP:
Tighten the clamp bolts again once this
position has been determined.
If the user is self-propelling check
that the user is able to reach the wheels
comfortably to push the wheelchair safely
and eciently. The TESS BACK laterals
should not hinder movement of the user’s
arms or prevent him/her from pushing the
wheelchair comfortably.

TOOLS REQUIRED:

FINAL STEP: RETIGHTEN BOLTS
Also recheck two nger /30mm
gap between Trunk Side Support and the

With the user leaning forward and the
assistance of someone offering support in
the front, the trunk side supports can be
positioned into place on either side of the
user’s trunk.
Tighten these bolts when the appropriate
support has been determined.
Make sure to tighten each nut securely,
but not too tight as it may damage the
thread.
Always make sure to check the
pressure between the user’s trunk and
the side support.

Regular check ups and proper care will increase the lifespan of the TESS BACK and ensure
the safety and wellbeing of the user.
CAUTION:
Don’t tamper with the setup of the TESS BACK.
It is important that you don’t change the settings or foam padding in any way once the
TESS BACK has been fitted by the therapist. The TESS BACK will have been selected and
fitted to give the correct amount of support for the user’s specific needs.
Contact your therapist should you have any concerns about the TESS BACK and its
function or comfort.*

REGULAR CHECKS YOU CAN MAKE:
All the tools needed for maintenance are supplied with the TESS BACK.

Remember to also keep the wheelchair and seat cushion in good working order with regular
cleaning and servicing. All these parts work together as a system to support the health
and wellbeing of the user.
Contact your seating service if you have concerns about your wheelchair or TESS BACK.
Check the condition of
the padding regularly to
ensure it is not damaged
and that there are no rough
or unprotected edges
against the user’s body.
Once a week check that
the nuts behind the back
and bolts on the brackets
are tight using the supplied
spanners.
Check the TESS BACK
brackets are placed in the
correct position on the
mounting clamps on
wheelchair back posts.
Check that the clamps
are in the correct
position and are fixed
firmly to the back-post.

reposition the clamp
and tighten the clamp
bolts.

MAINTENANCE CONT.
COVERS:
The covers can be removed for cleaning. The clean the outside fabric wipe clean with a
damp sponge and water. For hardier stains hand wash the covers with a little soap.
Never place in a washing machine, this will reduce their lifespan.
When removing the cover take care that the foam lining of the TESS BACK is not damaged.
This foam is important for pressure care. If there are any foam inserts, remove them and
wipe clean with a damp cloth or sponge.
CAUTION:
Never use TESS BACK without covers on.
CHECK UPS & SERVICING:
Clinical check-ups along with servicing the TESS BACK and wheelchair are recommended
at least every 2-3 months. This will ensure that correct alignment of the user is maintained
and that the wheelchair and supports are still providing them with appropriate support
and mobility.
It is especially important that the size and fit of the TESS BACK of a young user is regularly
monitored by their therapist.
