1. INTRODUCTION
Netti 4U comfort|CE/CES PLUS 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 German
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|CE/CES PLUS 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 offers the possibility to
vary the sitting position from activity to
rest using tilt and recline functions.
Max user weight: 135 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.

1.1 Areas of use/indications
Netti 4U comfort|CE/CES
PLUS
Netti 4U comfort|CE/CES PLUS 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|CE/CES PLUS 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 Contraindications
Netti 4U comfort|CE/CES PLUS is not suited
for persons with a strongly enhanced muscular
spasticity. In this case we recommend the
Netti III, which offers a version with reinforced
frame and leg rests 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
tube, the leg rests or the arm rests
1.3 Quality and durability
The Netti 4U comfort|CE/CES PLUS
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.
