Seat configuration
The seating system will be delivered already set up to the measurements recorded
during the assessment. If measurements were not provided when the seat was
ordered, the chair should be pre-set by the clinician at the seating clinic before the
user is positioned in it.
Your seating system should be already set up and adjusted by a qualified
prescriber. Clinical suitability and stability of the seating system should also be
checked at delivery.
If the wheelbase is a tilting type, you may find it useful to tilt the base when
positioning the user in the seating system. This will help to position the pelvis back
against the backrest with the help of gravity.
With the user in the seat, it is a good idea to check the supportive components in a
methodical way. Start by ensuring the pelvis is adequately supported, and then
work towards the feet. Afterwards, work upwards from the pelvis. We suggest this
order:
1. Pelvis back against back cushion and pelvic strap in place
2. Knees in position
3. Feet in position on the footrest and footstraps attached
4. Trunk harness in place if used
5. Head in position on the headrest.
If you had tilted the seat for the transfer, reduce the tilt to the appropriate
position.
It is important to check the seat, particularly the adjustable parts, during the first
few weeks of use. Most importantly, check the effect the seat has when it is first
delivered. Tell the fitting team if you have any cause for concern, e.g. if the person
has very red knees or a sore bottom, or if they do not even want to use the seat.
The seat will be providing a new posture for the user to learn. Try to avoid
introducing other new things at the same time! Do not let them sit in it for too long
when they are just getting used to it. Check with your therapist if you are unsure
how long to expect them to use the seat at first.
Small adjustments, by the seating team, may be necessary during the first few
weeks or so, as the user becomes accustomed to the seat.
After initial set-up adjustments are made, you should check the seat daily for fabric
wear and to check all the parts are operating to a good standard.

Using the seating system
The CAPS II Seating system has been specifically designed to meet demanding
postural requirements, whilst being very adjustable, adaptable and easy to use.
The following information is intended for general use of your seating system that
are appropriate for all users. Adjustments to the seating system not outlined in this
manual should be completed by a competent Therapist or Rehabilitation Engineer.
There are many options available with the CAPS II seat to ensure an appropriate
posture is maintained. Please read the appropriate sections based upon the seat
you have been provided. If you are unsure, please check with your prescriber.
Many of the parts are removable from the wheelbase to make handling it easier.
Some parts are fixed and not removable. When the seating system is handed over
to you, this should be demonstrated to you.
You should also read carefully the user manual provided for the wheelchair.
The seating system can be removed from the wheelbase to enable it to be used on
a second wheelbase. To reduce the weight of the seat unit, first take out the
removable components.

opposite to allow the complete footrest to be removed.
When replacing the footrests, ensure they are fully locked into position and the
footstraps attached where required.

Straps
The pelvic strap and harness should be clipped into position and tightened. When
the seating system is handed over, you should be shown how tight it should be. If
the user is hoisted into the seating system, the straps should be attached before
removing the hoist and sling.
Before clipping the straps together, do a quick check to ensure the webbing is not
twisted or caught.
Different types of harness are used on the seating system. Both the Top Pull and
Rear Pull Harnesses are tightened from the rear. The Front Pull harness is tightened
from the front.

Rear Pull Harness
Tension is adjusted by pulling
the webbing loop towards the

Seat Options
The seating system may be supplied in one of a number of configurations with
several possible options fitted. If you have any of these fitted to your seat, the
clinician will let you know when the seat is handed over to you.
3.1
Lynx Backrest
A Lynx Seating System has a special backrest whose shape can be changed over
time. This can be to accommodate changes in posture. It consists of a number of
interlinked plastic components. This will typically be fitted to the backrest of the
seating system. The seat in the photo above is shown with the backrest covers and
cushion removed.
!
The Lynx backrest is not user adjustable. Please
refer to your clinician if you feel adjustment of
modification may be required.

Identifying when adjustment is needed
It is important to understand when the seat may need adjustment. Adjustment
should only be carried out by your seating team or a competent person.
4.1
Seat depth
The seat depth may be too short if the back of the user’s legs touch the front of the
seat cushion when their pelvis is fully back against the back cushion.
The seat depth may be too long if there is a gap of more than 2” between the back
of the user’s legs and the front of the seat cushion when their pelvis if fully back
against the seat cushion.
4.2
Footrests
The footrests may be too high if the there is a gap between the underneath of the
user’s leg and the top of the seat cushion, or the legs are not parallel to the base of
the seat cushion.
The footrests may be too low if the feet do not make contact with the footrests.
4.3
Lateral supports
The top and bottom lateral supports should be aligned so that the client can be
positioned with their regular clothing.
The laterals may be too close together if it is difficult to fit the user between them.
The laterals may be too far apart if the user leans to one side.
The top laterals may be too high if they are touching the user’s armpit. There
should normally be a gap of between 1” and 2”.
The laterals may be too low if the gap between the top of the lateral pad is bigger
than 2”. Very occasionally thoracic laterals may be set lower for someone who has
good trunk ability, for example of help facilitate self-propulsion on a manual
wheelchair.
