Changing the cover
It is easiest to remove the knit microfiber cover with
the seat taken off. To do this, secure the base of the
foot with both of your feet (preferably without shoes,
to avoid scratching the base) and pull on the seat
while turning it. Then loosen the four screws of the
retaining ring and remove the cover. To put the cover
back on, pull it tightly and evenly over the seat cush-
ion, use the retaining ring to push the thick ring along
the edge of the cover to the seat, and secure the
ring again by tightening the four screws. Then put
the seat back on the pneumatic height adjuster and
secure it on the cone by sitting on it several times.
Seat covers made out of skai® leather or genuine
leather cannot be changed, but the whole seat may
be replaced.
Care
• To clean the microfiber cover, it can either be left
in place and cleaned with standard commercially
available cleaning products, or it can be removed
and washed with mild detergent (either by hand
or in the machine) or dry cleaned.
Clean skai® leather regularly with a mild foaming
soap and a microfiber cloth or a soft hand
brush. Stains caused by oils, grease, or ink must be
removed immediately. For genuine leather, use a
mild leather care product regularly. If necessary,
clean with lukewarm water and a soft cloth. Please
do not use solvents, chloride, abrasive, or chemical
cleaning agents. Please note that discoloration
caused by jeans or other textiles is excluded from
any manufacturer’s warranty.
• The plastic parts can be kept clean with mild,
diluted household cleaners and a soft cloth.
Do not use solvents or abrasive materials.
Recycling
Sustainability and durability are top priorities in all
of our design, production, and distribution activities.
Short transportation distances reduce environmental
impact. The materials of the stool can be separated
relatively easily for recycling. The components either
have material labels or can be identified easily using
the material list. Dispose of individual materials and
components properly according to local recycling and
disposal requirements. To avoid unnecessary transpor-
tation, the main components of the ONGO®Free are
manufactured by a capable, ISO-certified company,
configured with other components (pneumatic height
adjuster, cover, etc.) according to the customer’s spe-
cifications, and shipped directly. ONGO® GmbH ac-
cepts discarded stools for recycling.
Made in Germany
The design, origin of the materials used, and as-
sembly of our products stand for lasting quality and
durability.
Warnings
•
Seek medical advice before using.
Although
physicians were involved in the development and
testing of the stool, you should consult your doctor
or physical therapist regarding proper use in your
specific case, especially in case of acute back pain.
•
Tipping hazard.
Despite the non-slip coating of the
foot base, inappropriate movements can cause the
base to slide outward, causing the stool to tip over.
Do not stand or balance on top of the stool. Do
not use the ONGO®Free as a ladder. Be particularly
careful with children who cannot yet reach the
floor with their feet when sitting on the stool.
