1. INTRODUCTION
Netti 4U comfort|CED(S) is a comfort
wheelchair meant for both indoor and out-
door use. It is tested to DIN EN 12183:2009.
The tests were carried out by TÜV SÜD Product
Service GmbH in Germany.
In Alu Rehab we believe that wheelchairs
should be chosen based on a thorough
assessment focusing on the needs of the
user and demands from the environment.
Therefore it is important to know about
the possibilities and restrictions of the
wheelchair. Netti 4U comfort|CED(S) is a
wheelchair designed for users with the
need for comfort and relief. The combi-
nation between the seating system and the
ergonomical solutions in the frame construction,
oers many possibilities for adaptation and
adjustments.
The wheelchair is constructed for indoor and
outdoor use, and oers the possibility to
vary the sitting position from activity to
rest using tilt and recline functions.
Max user weight Netti 4U comfort|CEDS: 130 kg.
Max user weight Netti 4U comfort|CED: 160 kg.
When mounting accessories such as
power kit etc., the weight of the
accessories must be subtracted from the
max user weight.
Specifications varies between
countries.

1.3 Quality and durability
The Netti 4U comfort|CED(S) wheelchair
is tested at TÜV SÜD Product Service
GmbH in Germany, following the
European Standard DIN EN 12183:2009.
As manufacturer, Alu Rehab A.S
evaluates the test to be equal to 5-6
years of normal use of the chair. The
disability of the user as well as the level
of maintenance done foremost decides
the durability of the wheelchair. Thus,
the durability will vary depending on
these two factors.
1.4 The environment and
waste disposal
Alu Rehab and its suppliers wish to
protect the environment.
This means:
• That we avoid using
environmentally harmful
substances and processes
to the greatest extent possible.
• That Alu Rehab’s products are
ensured a long service life and a high
degree of flexibility - to benefit the
environment and economy.
• That all packaging can be recycled.
• That the wheelchair was designed to
be separated into its component
materials - to make recycling easier.
Contact your local recycling agent
to get correct information how to
handle in you area.
1.1 Areas of use/indications
for Netti 4U comfort|CED(S)
Netti 4U comfort|CED(S) is a multi-function
wheelchair for partially or fully immobile
persons with physical and/or mental
disabilities. These disabilities may have
multiple causes. Netti 4U comfort|CED(S)
has an adjustable seat and back angle,
thus facilitating for the user change of
position, mobilisation or posture correction
(stabilisation), wherever the following
functional impediments with their multiple
possible causes are present:
• limited or lacking mobility
• limited or lacking muscle power
• limited movement range
• lacking or limited trunk and body stability
• hemiplegia
• rheumatic-type disorders
• craniocerebral injuries
• amputations
• other neurological or geriatric disorders
1.2 Contra-indications
Netti 4U comfort|CED(S) is not suited for
persons with a strongly enhanced muscular
spasticity. In this case we recommend the
Netti III, which oers a version with reinforced
frame components and foot support for this
particular need.
Ignoring this advice could in unfavourable
circumstances lead to the deformation or
fracture of metal parts in the area of the back
