By nature our bodies are designed primarily for walking. To keep us fit, our joints, muscles and metabolism need our hips to move frequently and to employ as varied a range of motion as possible. Because our hips are our bodies' powerhouses. Which is why over ten years ago Wilkhahn decided to teach seating to walk. It used three-dimensional kinematics to stimulate natural movement and ensure our bodies maintain their centre of gravity - whatever the posture. Trimension was developed in close collaboration with the Centre for Health at the German Sport University Cologne and has now been adapted for IN.
