1. INTRODUCTION
Netti Vision is a comfort wheelchair meant for

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 Vision is a wheelchair designed for users with
the need for comfort and relief. The combination
between the seating system and the ergonomically
solutions in the frame construction, oers many
possibilities for adaptation and adjustments for
long time seating.
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: 100 kg.

1.1 AREAS OF USE /
INDICATIONS FOR
NETTI VISION
Netti Vision is a foldable multi-function wheelchair
created for only attendant handling, for partially
or fully immobile youth and grown up persons
with physical and / or mental disabilities. These
disabilities may have multiple causes.
Netti Vision has an adjustable seat and back angle,
thus facilitating for the user change of position,
mobilization or posture correction (stabilization),
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 Vision is not suited for persons with a strongly
enhanced muscular spasticity. In this case we
recommend the Netti Dynamic System, which oers
a frame construction that follows the movement
pattern of the user. Ignoring this advice could in
unfavorable circumstances lead to the deformation
or fracture of metal parts in the area of the back
tube, the legrests or the armrests.
1.3 QUALITY AND DURABILITY
Netti Vision has been tested at TÜV SÜD Product
Service GmbH in Germany following the European
Standard EN 12183:2014.
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.
In normal use Alu Rehab A.S. expects the service
life to be 5 – 6 years. In practice the service life
will depend strongly on external factors including
disability of the user, environment and wether
regular maintenance has been carried out.
