Sitness 4D
Together with Swiss designer Thomas Walser, we have redefined healthy and dynamic sitting. The Sitness 4D impresses with its iconic design and innovative technology: its seat and body rotate 360 degrees, while floating compression and tension springs offer a unique, almost weightless sitting experience. This activates the back muscles and promotes an upright posture – with maximum fun factor.

Sitness 4D is a certified model from Aktion Gesunder Rücken e.V. in the active chair category.
With our AGR-certified models, you can create the most important component of a healthy working environment. Our unique Sitness technology ensures three-dimensional sitting. The freedom of movement in every direction ensures more active sitting, which unconsciously trains the back muscles and prevents back pain.
