Thank you for choosing the innovative ONGO®School.
People have been made by Mother Nature to move.
The same can be said when it comes to the brain.
Movement supports the flow of blood in the body,
and coordinated movements improve the nerve sys-
tem’s functionality. Which leads us to the essentials
of the ONGO®School:
It fosters movement while sitting. This is achieved
through the use of a rounded foot, a fixed seat, and
the elimination of a backrest.
Positive eects of active sitting in comparison to
sitting on static furniture are:
• Improved concentration and better ability to learn
due to improved blood circulation and uptake of
oxygen.
• Enhancement of coordination and balance, which
play an important role in the development of the
brain and nervous system.
The positive eects mentioned above are partly ac-
companied by additional eort when sitting. There-
fore stools like the ONGO®School are not designated
as a main seating for education institutes.
Best sitting height ONGO®School fix
Choose the height from the four heights which are
available according to the need of its user. To do so,
you may orient yourself on the DIN EN 1729-1. Please
note, however, that active sitting with its tilted po-
sition generally calls for taller sitting heights, which
correspondingly call for higher table tops. In each
case put the feet on the floor. Recommendation of
seat heights corresponding to body height according
to DIN EN 1729-1:
The ONGO®School flex has a seat height range from
43 to 62 cm (17–24.5 in).
Assembly ONGO®School flex
Out of respect for the environment the ONGO®School
flex will be sent in a size-optimized box. For this the
ONGO®School flex has been separated into its three
main components (seat,
gas spring and foot).
To assemble remove the
protective packaging from
the three parts, set the
foot on the ground and
insert the gas spring into
the cones. See Fig. 1.

After this, place the seat on the gas spring and sit
down on the seat firmly so that the cones get a
good grip.
Height adjustment ONGO®School flex
The seat adjusts precisely to your needs. To adjust
the height, sit on the ONGO®School flex and push the
lever under the seat.
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 transportation, the main com-
ponents of the ONGO®School are manufactured by
a capable, ISO-certified company, configured with
other components according to the customer’s spec-
ifications, and shipped directly.
ONGO® GmbH accepts 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®School as a ladder. Be particu-
larly careful with children who cannot yet reach
the floor with their feet when sitting on the stool.
• Proper use of the ONGO®School. The ONGO®School
has been designed for dynamic, healthy sitting. It
has not been designed and manufactured for any
other purposes. Use the ONGO®School only for the
intended purpose.
• Use by one person only. The ONGO®School was
designed and manufactured only for the use by
one person at any time. If it is being used by sever-
al persons simultaneously it might collapse and
cause serious injuries.
Its maximum load is 110 kg or 243 lbs.
• Use of force. Any misuse and/or application of
force on the ONGO®School might result in serious
physical injuries.
• Pneumatic height adjuster: Do not perform
mechanical work on it. Working on or
replacing the pneumatic height adjuster must be
performed by trained personnel only.

• Packaging material. Dispose of any packaging
material properly. Keep packaging material out
of the reach of children. A risk of suocation might
occur.
