In today’s busy office environment we all spend long periods of time in hunched positions at our desks. Bizarrely, despite being bad for our bodies we choose to adopt a lazy posture. What the human body actually requires is frequent and a varied range of movements. Wilkhahn understands this key principal of ergonomics which is why we have developed Trimension® for the ergonomic ON chair. This unique tested feature is a patented technology for three dimensional, synchro-adjusted dynamic seating. Trimension® doesn’t just encourage forwards, backwards and sideways movements, but the pelvis to rotate too - which is so important for the spine’s stability. Two separately moveable swing plates, just like two thighs, lie at the core of the technology. Minimal shifts in weight are already translated into movement.
