Artavara Topeno 

The Topeno office chair reduces the strain that your body experiences
while working seated. The chair is originally designed for musicians
who need freedom of movement while playing. It features the
ArtAvara patent protected suspension design, that allows for seamless
360 degree movement, reduces the strain on your lower body and
helps with lymphatic circulation. 

Topeno chair helps you keep focused on the task at hand, as your body stays
active even though you have the comfort of being seated.
