CARING
FOR YOUR
CHAIR
We offer a full range of service
parts to keep your chair well
maintained so it provides you with
the comfort and support you need.
Removal of dirt, dust and debris
is recommended and regular
vacuuming will help keep the
upholstery clean, whether it is
fabric, vinyl or leather. Please
ensure you use a soft vacuum
attachment and keep suction to a
minimum to avoid scratching and
lasting marks. The hardware can be
wiped down with a damp cloth as can
vinyl and leather upholstery. Fabric
upholstery may need the addition
of a fabric cleaner that has been
specically formulated for use on
upholstery.
Periodically cleaning your castors is
recommended to avoid the build-up
of debris as this can make the chair
harder to manoeuvre. A small spray
of WD-40 will help to keep the
castors rolling smoothly.
Periodic maintenance of the
chair is required and a thorough
visual inspection of the main
components is necessary to ensure
user safety. Do not attempt to
open any mechanism or remove
any plastic parts as only authorised
professionals are permitted to do
so. If the product shows reduced
or altered performance, please
contact the dealer or manufacturer.

backwards to release the
rocking action. Ensure you brace
yourself in case the tension is too
strong or too weak. Ideally you want
the chair to follow and support your

If you feel the chair pushing
you forward then decrease the
tension by turning the wheel
clockwise. If you feel the chair tilt
backwards too easily then increase
the tension by turning the wheel
anti-clockwise
Ensure the rocking action is
locked prior to getting in or out
of the chair by pushing the lever
forwards
