gravity lies within the points of contact of the forward and
rear wheels with the ground.
- Weight Limit
The maximum recommended weight of the user is 125kg
and 137 kg for the Heavy Duty version. However, the level of
activity is an essential factor. For example, an active user who
weighs 75 kg may subject the wheelchair to more stress than
user who weighs 100 kg. To this purpose, we recommend
that you consult your retailer when choosing the model of
wheelchair based upon your daily life style.

The limitations on reaching out from a wheelchair indicated
in the following diagrams have been calculated based on a
representative sample of wheelchair users:
- Only the arms should be extended beyond the seat of the
wheelchair. (gure 2).
- In any case the body and head shouldn't remain without the

- Stability and balance
Your wheelchair has been designed to provide the stability

the position of the centre of gravity, which may lead to the
wheelchair tipping and a fall.
To improve your safety when you move a lot or you
transfer your weight from one place to another, we
recommend using seat belts.
- Weight distribution (gure 1)
Many actions cause the user of a wheelchair to reach
out, lean over or move about within the wheelchair and
outside it. Any movement you make whilst sat in your
wheelchair will move the combined centre of gravity (Gc)
of you and the wheelchair (Gw). You will remain stable in
the wheelchair whilst the line of your combined centre of
