WARNING
RISK OF ACCIDENT, INJURY, PAIN OR DEATH IF WARNINGS ARE NOT FOLLOWED
Ask for help if you are unsure about any of the following points.
1. Check your skin for red marks or pressure spots regularly. If your skin is red
or itchy, stop using the cushion and consult with your healthcare professional.
2. Never use the cushion without the Overlay foam. Failure to do so may result
in pressure injuries.
3. Never use the cushion without a cover. Stay away from open flames or burning
cigarettes. Using the cushion without a cover increases the risk of flammability and
skin damage.
4. Never exceed the weight limit of your cushion or your wheelchair. The weight limit
of the wheelchair is specified by the wheelchair manufacturer. Never perform
exercise weight training that could exceed the weight limit of the wheelchair.
5. Check if anti-tippers or other adaptations need to be added to the wheelchair to
help increase stability. Installing seating systems may aect the centre of gravity
and could cause the wheelchair to tip.
6. The Spex Constructa Cushion has been designed as a cushion for wheelchair
users. Never use your cushion in ways it is not designed to be used.
7. Adjusting the cushion can change the pressure distribution. Only clinicians who
are skilled in wheelchair seating should adjust the cushion. They could be an
Occupational Therapist, Physiotherapist, or other health professional with training in
wheelchair seating and positioning. Adjustment should follow a proper assessment
of the user’s needs.

Adjust the Cushion
The Spex Constructa Cushion works for dierent
body positions in people with disabilities or sitting
challenges. By changing the base foam, the cushion
surface adjusts to help with overall posture, pelvic
alignment, sitting ability, comfort and pressure
distribution.
Always put the Overlay on top of the base foam before using the cushion, even when setting it up. The
Overlay helps reduce pressure and blend gaps in the base foam.
When setting up the cushion, it might be easier to make changes without the Inner Cover. During the
assessment process you can test the cushion adjustments by attaching the overlay to the top of the
positioning base. Use the front flaps to keep it in place.
Once the base foam is adjusted, fit the Inner Cover, attach the Overlay and fit the Outer Cover and
check the cushion function.
Caution:
• Ensure the Ischial Tuberosities are positioned on the ischial insert foam. If positioned incorrectly (on;
Trochanter Blocks, Contours, Pre-Ischial Shelf, Thih Blocks), this may result in pressure injuries.
• This Cushion must be trailed first to determine its eectiveness in meetin the needs of the user.
The clinician must inspect the user’s skin to ensure that red pressure spots are not developin.
Base Adjustment
The Strategic Positioning Kit allows you to add or remove
Pelvic and Thigh Positioning Pads to adjust the cushion for
dierent needs, such as:
• Correct or accommodate pelvic obliquity
• Support minor flexion limitations
• Ramp the cushion to provide anti-thrust
• Dump the cushion provide added stability
• Anle the cushion to aid puntin
The Constructa Flex base has more adjustments for users
with complex needs. If you have a Constructa Shape, you
can go to ‘Positioning Block and Contour Adjustment’.

SPEX CONSTRUCTA USER MANUAL 8spexseating.com
Constructa Flex Base Adjustment
Make adjustments to the base to change the shape of the cushion surface. Removing some of the
positioning blocks may make it easier to adjust. The base should be adjusted before the contours.
Images (for illustrative purposes only) Description of Adjustment
Hip/Thigh Angle
Remove the Leg Wedge to lower the leg (open hip angle).
To increase the angle, reattach the wedge in reverse
(thinner edge to the front). This will be 15 degrees.
Wedges can be added to raise the thighs (reducing the
hip angle).
Pelvic Height
Adjust the pelvic height by adding or removing Ischial
Pads.
When the thigh angle is lowered to 15 degrees or more,
extra ischial pads must be added.
Internal and External Rotation
Rotate the Leg Wedge by 90 degrees.
The wedge may need to be trimmed to fit.
Pelvic Obliquity
Add or remove Ischial Pads.
To accommodate a pelvic obliquity, add pads to match
the posture.
To correct a pelvic obliquity, do the opposite.
Flip the pads when moving them between the left and
right sides.
Leg Length Discrepancy or Seat Depth
Leg length can be shortened by 1” using the puzzle joint.
Peel up the leg and reattach further back in the puzzle
joint.
To increase the discrepancy; extend the other leg as
much as possible.
For seat depth adjustment; do the same on the other leg.
To reset; position the legs with a 1” (25mm) gap in the
back of the puzzle joints.

SPEX CONSTRUCTA USER MANUAL 9spexseating.com
Images (for illustrative purposes only) Description of Adjustment
Abduction and Windsweeping
Adduct or abduct either one or both legs using the puzzle
joint adjustment. Peel up the leg and reattach at the
desired angle.
Pay attention to the leg length to ensure it is not too long
or short as this is also adjusted at the same time.
Positionin Block and Contour
Adjustment
These adjustments apply to both Shape and Flex cushions, the only dierence is the split between the
legs. The Constructa Flex cushion has pairs of: thigh block, pre-ischial shelf and medial contour pad.
We recommend making the Flex Base adjustments (see previous) before refining the Positioning
Blocks and Contour Pads.
Images (for illustrative purposes only) Description of Adjustment
Pelvic Width
Move the Trochanter Blocks in or out to match the pelvis.
Done correctly this will load the greater trochanters and
ooad the ischial tuberosities (ITs).
Move the Lateral Pelvic Contours in or out to support
the pelvis and load the greater trochanters and hips
eectively.
Make sure the inner edge of the Lateral Pelvic Contour
does not sit over the Trochanter Block undercut as this
will increase pressure in the ischial well.
Seat Width
The Lateral Pelvic and Lateral Thigh Contours can be
adjusted in or out to support a narrower or wider user.
Make sure the pelvic width is adjusted correctly using
both the Trochanter Blocks and Lateral Pelvic Contours
(detailed above)
SuperHigh and Standard contours are designed for width
reduction only.
High contours can also be moved 1” wider if needed.

SPEX CONSTRUCTA USER MANUAL 10 spexseating.com
Images (for illustrative purposes only) Description of Adjustment
Seat Depth and Pelvic Positioning
Move or remove the 5cm Thigh Block to reduce the seat
depth (bringing the Pre-Ischial Shelf forwards). This is
also useful for supporting in posterior pelvic tilt.
Curve and form the Pre-Ischial Shelf to support the
pelvis eectively.
Abduction and Windsweeping
Lateral Thigh and Medial Thigh Contours can be moved
to accommodate for abduction, wind sweeping, internal
and external rotation.
Pelvic rotation
For pelvic rotation; the 5cm Thigh Block can be removed
or cut in half to allow the Pre-Ischial Shelf to be moved
further forward on one side.
To correct a flexible rotation, build up the shelf as
detailed below, ‘Anti-Thrust Support’
Thigh contours can also be positioned to accommodate
rotation.
Anti-Thrust Support
Add Thigh Positioning Pads under the base to build up
the front of the cushion.
For an abrupt shelf, add them between the Thigh Blocks
and the Base.
To further block the ITs and restrict forward migration,
remove the Pre-Ischial Shelf and position the 50mm
Thigh Block in its place.

SPEX CONSTRUCTA USER MANUAL 11 spexseating.com
Other Foam Adjustment Tips
Adjustments must be based on biomechanical evaluation and assessment.
• Trochanter Block position is important to support the pelvis and maximise pelvic ooading.
• Thigh Blocks and Trochanter Blocks can be inverted to increase support and reduce immersion
in some areas.
• Gaps between the base foam components are acceptable, but ensure the Overlay is positioned
correctly before fitting the Outer Cover. The Overlay is needed for pressure management and
blending the contours of the cushion.
• To correct an anterior pelvic tilt: Leave the base foam flat or slightly raise the front of the base foam
for neutral alignment of the pelvis or promoting weight bearing on ischial tuberosities.
• Positioning Blocks, Contours, and Bases can be cut to expand the adjustment range – replacement
parts are available from our Constructa Cushion Spare Parts Script.
Caution:
Only use genuine Spex covers, accessories, and components with your cushion.
Installin the Covers and Overlay
Once the base foam is adjusted, fit the Inner Cover. This is a loose fit to allow for adjustment to the
base foam.
Caution:
• Never use the cushion without the Inner Cover. Failure to do so will reduce the life of the cushion.
• Overlay foam must be used with the Overlay cover, with the flaps and the straps attached. Failure
to do so will allow the overlay to move and may cause pressure injuries over time.

SPEX CONSTRUCTA USER MANUAL 12 spexseating.com
1. Place the Overlay on top of the cushion and line up
the front edge with the front edge of the Inner Cover.
2. Press the Overlay into the leg troughs to match the
cushion profile. Pull the Front Flaps tight and attach
under the base.
Make sure the Overlay is centred on the cushion.
Flex only: Attach the inner leg straps firmly under the
cushion. Make sure the Medial Contours are covered
by the Overlay and the Overlay is aligned with the inner
edge of the cushion.
3. Loop the 4 side straps from the Inner Cover up and out
through the Overlay loops. Fold the strap back down
and attach to itself. Set the tension so the overlay is
held in place but not too tight.
Caution:
Overlay side straps must not be too tight. This could
cause the Overlay to hammock and reduce the pressure
management of the cushion.
4. Attach the rear flap under the cushion to stop the Overlay
from sliding forward. This flap does not need to be tight.

SPEX CONSTRUCTA USER MANUAL 13 spexseating.com
Fittin the Cushion
1. Position the cushion about 1cm forward
of the front edge of the seat base to
protect the user’s legs.
Constructa labels on the sides of the
Outer Cover show the front of the
cushion. The front of the cushion must
always face forwards.
• Handle is at the front
of the Constructa Shape
• Handle is at the back
of the Constructa Flex
2. Check the size of the cushion. The cushion must fully support the base of the user. If the
cushion is too long it may force the user to sit with a posterior pelvic tilt.
3. Proper foot position may enhance sitting comfort. Adjust the foot supports so the user’s legs
are supported by the cushion and the foot supports.
Maintenance and Cleanin
Monthly cleaning and regular maintenance will help extend the life of the cushion. The expected
lifetime of the cushion is 5 years; however, the cushion needs to be checked regularly for
performance.
Spex recommends using AHP (Accelerated Hydrogen Peroxide) disinfectant wipes. The disinfection
product must be used as per the manufacturer instructions. Spex takes no responsibility for the
eectiveness of the disinfecting process.
Caution:
• Replace the cover correctly after washing. Check the back of the cover matches up to the back
of the foam base.
• Use only Spex Constructa Covers on Spex Constructa Cushions. Changing the Outer Cover,
or using dierent materials, will alter the cushion performance.
Foam
• Keep dry.
• Check the foam base regularly to ensure good foam consistency.
• If it accidentally becomes wet, dry thoroughly before replacing the covers.

SPEX CONSTRUCTA USER MANUAL 14 spexseating.com
Outer Cover
• Remove the cover from the foam base and turn inside out.
• Machine wash in warm water (40°C / 104⁰F)
• Drip or tumble dry on low heat.
• Do not iron. Do not dry clean. Do not bleach.
• If chemical cleaners are used, covers must be rinsed thoroughly with water to remove all chemical
residue and left to dry completely before reuse.
• Check the cover for tears and excessive wear and replace it if ripped, torn or otherwise not fully
functional.
• If used in an institutional setting, write the resident’s name with a permanent marker on the content
label of the covers. This will help to ensure the return of the covers after washing.
If you have any additional questions regarding cleaning procedures, please contact your authorised
Spex Seating dealer.
Assembly, Use, Maintenance
and Limitations
• Adjustments to the set-up of the wheelchair must only be carried out by a qualified therapist,
professional, or seating technician. Custom contoured/bespoke systems may require a qualified
professional to configure and install the seating system.
• After carrying out any adjustments ensure all bolts, screws and nuts are securely fastened again to
ensure safety when travelling in a vehicle.
• Ensure the top and bottom mounts of the backrest and the front and rear mounts of the seat pan
are installed as far apart from each other as possible to give a stronger 4-point attachment to the
wheelchair frame. Ensure the quick release latches are engaged.
• Do not use the Spex Seating System as a vehicle seat if seating components which have not been
successfully crash tested are used anywhere on the seating system. Spex seating is designed and
certified using only Spex components. Spex is not liable in the event where other manufactured
seating systems are used in conjunction with Spex seating.
• At regular intervals check that all the fastenings on the Spex Seating System have not become
loose during day to day use and re-tighten if necessary.
• Ensure the swing-away laterals are in their locked position before using the seat as a vehicle seat
in a motor vehicle.

SPEX CONSTRUCTA USER MANUAL 15 spexseating.com
Transit Safety
The Spex Seating System has been successfully crash tested and complies with RESNA WC-4:2017,
Section 20 (WC20). The Spex Seating System meets the requirements of ISO 16840-4:2009 and is
suitable for use as a motor vehicle seat when used with an appropriate wheelchair base. Please follow
all installation, use and maintenance instructions within this manual as well as the following transit
instructions. If feasible, the wheelchair user should transfer to the vehicle seat and use the vehicle-
installed occupant restraint systems.
Spex Seating System has been designed to accommodate the proper use of vehicle-anchored belt
restraints. Spex achieved a rating of Excellent (16 out of 16), for ease of properly positioning a belt
restraint, and the degree to which proper belt restraint can be achieved, based on the methods of
Annex D. The following items of the Spex Seating System have been tested and are suitable for use
in a motor vehicle:
• Full Height Back Support Models
• Seat Base
• Cushion Models
• Arm and Thigh Supports
• Trunk Lateral Supports
• Head Supports
Note: Back supports that are lower than the user’s shoulder height are not certified and not
recommended for transport in a vehicle. Eg. Zygo Lo back supports.

SPEX CONSTRUCTA USER MANUAL 16 spexseating.com
Correct Positioning of Belt Restraints
When using the Spex Seating System as a vehicle seat, both a
pelvic- belt restraint and shoulder-belt restraint must always be
used. To correctly position the belt restraints on the wheelchair
occupant, the following must be ensured:
• The pelvic-belt restraint should be worn low across the front of
the pelvis near the junctions of the pelvis and thighs.
• The angle of the pelvic-belt restraint should be between 30° to
75° relative to the horizontal and, ideally, between 45° to 75° to
the horizontal (as shown in Figure 2).
• The belt-restraint buckle of three-point belt restraints should
be placed in contact with the occupant’s body and away from
wheelchair components.
• The junction of the shoulder-belt and pelvic-belt of three-
point- belt restraints should be located near the hip opposite
the shoulder over which the diagonal belt crosses and not near
the midline of the occupant.
• Belt restraints should not be routed outside of the wheelchair
wheels or over the wheelchair armrests, and should not be held
away from the body by wheelchair components or parts.
• Upper torso belt restraints should fit directly over, and in contact with, the middle of the shoulder.
• Belt restraints should be adjusted to fit as snugly as possible, consistent with user comfort.
• Belt restraints should not be worn twisted in a manner that reduces the area of contact of the belt
webbing with the occupant.
