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.

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 eciently. The TESS BACK laterals
should not hinder movement of the user’s
arms or prevent him/her from pushing the
wheelchair comfortably.

positioned into place on either side of the
user’s trunk.
Tighten these bolts when the appropriate
support has been determined.

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.
