A small shift in weight and the seat responds. That perceptible moment begins with the Top Unit: the movement mechanism directly beneath the pelvis.
What does the Top Unit do?
The Top Unit gives the seat room to tilt and rotate. Beneath it, the Penthapod® provides a stable five-point base. Together, they allow movement while keeping you firmly seated.Where does the measurement data come from?
In the Pro models, sensors record the movement of the seat. Sit-i Pro shows direction and change. The sensors therefore measure the movement of the chair; they do not directly measure the movement of the pelvis or lower back.From recording to insight
Repeat a movement, compare left and right and see what changes. As a professional, you connect that information with what you see, feel and know about the person and the situation. Measurement data then becomes a starting point for a focused question or the next exercise.Discover the system
