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

1.1 Quality and durability

The disability of the usage 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.

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.
• That the wheelchair was designed with
many different auxiliary functions - to
improve the working environment for
staff at instutions and hospitals.
