1. INTRODUCTION
Netti 4U comfort|FA 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|FA 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,
offers 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: 140 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
for Netti 4U comfort | FA
Netti 4U comfort|FA 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|FA 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|FA 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|FA 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.
