Ongo Roll Product guide

Thank you for choosing the innovative ONGO®Roll.
In fact the ONGO®Roll should really be called “Rock
’n’ Roll” because the ergonomic design stool not only
rolls, but also rocks. The innovation lies in the flexible
seat bearing, with which the seat can be tilted. Thus,
the ONGO®Roll meets all the requirements for active
and thus healthy sitting while providing a maximum
range of motion.
Assembly
Out of respect for the environment the ONGO®Roll
is shipped in a size-optimized box. For this purpose,
the ONGO®Roll has been separated in its two main
components (seat with gas spring and 5-arm base with
casters). To assemble remove the protective packaging
from both parts, set the base on the ground and place
the gas spring in the intended opening. See Fig. 1.
After assembling the ONGO®Roll, sit down on the seat
firmly so that the cones get a good grip.
Height adjustment
The seat adjusts precisely to your needs. To adjust
the height, sit on the ONGO®Roll. Press the ring
under the seat down or pull it up on one side to tilt
it as you would a lever (H).
Adjustment of the flexible seat mounting of
theONGO®Roll Flex
The seat is mounted flexibly on all sides. The strength
of the connection can be adjusted through turning
the orange adjustment ring (S) directly below the
Operating and assembly instructions
seat. With a counterclockwise rotation the tilt is re-
duced (–) and with a clockwise rotation increases the
tilt (+), see Fig. 1. The ONGO®Roll operates without a
flexible seat.
Seat choices
The ONGO®Roll is available with a saddle seat or a
round seat.
Change of cushion
The cushion for the saddle seat of the ONGO®Roll
is optional and can be easily attached and subse-
quently removed from the seat for replacement. Fit
the cushion to the seat so that the lugs fit into the
holes provided, apply pressure to clip on. To remove
loosen the locking lugs on the bottom with slight
pressure and lift the pad. It is easiest to remove the
knit microfiber cover from the round seat. Loosen the
four screws of the retaining ring and remove the cover.
This can then be machine-washed or replaced. To put
the cover back on, pull it tightly and evenly over the

seat cushion, push the edge of the cover under the
seat and secure the retaining ring by tightening the
four screws. Seat covers made out of other materials
cannot be changed.
Caring for your ONGO®Roll
Cleaning the microfiber fleece on the saddle seat
cushion can be done with commercially available
cleaning agents. To clean the microfiber knit cover
on the round seat, it can either be left in place and
cleaned with standard commercially available clean-
ing products, or it can be removed and washed with
mild detergent (either by hand or in the machine)
or dry cleaned The skai® leather should be washed
regularly using slightly soapy water and a fine cloth.
Oil, fat and ink stains should be removed immedi-
ately. For real leather use a leather cleaning agent,
or warm water and a soft cloth. Please do not use
any solvents, chloride, polishing agent or chemical
washing agents.
To clean the wool fabrics by kvadrat, please vacuum
regularly. Greace or oil stains should be carefully
dabbed o with a clean cloth and lukewarm water.
Do not use any solvents, chlorides or chemical clean-
ing detergents. Please note that the staining by jeans
or other textiles is excluded from any manufacturer
warranty. The saddle seat can be kept clean with mild
household or plastic detergent and a soft cloth. Do
not use strong solvents or abrasives.
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 using
the material list. Dispose of individual materials
and components properly according to local recy-
cling and disposal requirements. To avoid unneces-
sary transportation, the main components of the
ONGO®Roll are manufactured by a capable, ISO-cer-
tified company, configured with other components
(pneumatic height adjuster, cover etc.) according to
the customer’s specifications and shipped directly.
ONGO® GmbH accepts discarded stools for recycling.
Made in Germany
The design, origin of the materials used and assembly
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. The ONGO®Roll has 5 castors of
which 2 can be fixed manually. This is to make sure
that the stool does not move unexpectedly side-
ways when the user does not put his or her weight
on the seat evenly. Please keep in mind that the
specific mobility of the ONGO®Roll requires special
care when using it. Do not use the ONGO®Roll as
a ladder. Be particularly careful with children who
cannot yet reach the floor with their feet when
sitting on the stool. The ONGO®Roll has been
designed for dynamic, healthy sitting. It has not
been designed and manufactured for any other
purposes. Use the ONGO®Roll only for the intend-
ed purpose.

• Use by one person only. The ONGO®Roll was
designed and manufactured only for the use by
one person at any time. If it is being used by sev-
eral persons simultaneously it might collapse and
cause serious injuries.
Its maximum load is 110 kg or 243 lbs.
• Do not perform mechanical work on the pneu-
matic height adjuster. Working on or replacing the
pneumatic height adjuster must be performed by
trained personnel only.
• Use of force. Any misuse and/or application of
force on the ONGO®Roll might result in serious
physical injuries.
• Packaging material. Dispose of any packaging
material properly. Keep packaging material out of
the reach of children. A risk of suocation might
occur.
