Say good-bye to sitting still!

Congratulations on your purchase of the ONGO®Kit. 
With the curved surface of its base, it supports the 
natural urge for movement especially in children and 
so continuously activates  important muscle groups 
in all regions of the body. Positive effects of active 
sitting in comparison to sitting on static furniture are:

•  Improved concentration and better ability to 

learn due to improved blood circulation and up­
take of oxygen.

•  Enhancement of coordination and balance, which 

play an important role in the development of the 
brain and nervous system.

The innovation consists of the curved base and 
the integrated balltrack. Every movement on the 
ONGO®Kit brings the ball into motion and motivates 
you to active sitting.

Best sitting height

Adjust the height of the ONGO®Kit with the sepa­
rate height extension kit according to the need of its 
user. To do so, you may orient yourself on the DIN 
EN 1729­1:2006­09. Please note, however, that active 
sitting with its tilted position generally calls for taller 
sitting heights, which correspondingly call for higher 
table tops.
