Motion – The New Ergonomics


The Lyrical Chair is comfortable and engaging sitting. It introduces a small element of instability, and the natural balancing instinct brings the muscles into play. The Lyrical Chair healthfully relieves both the pain and stiffness that come from sitting. We make chairs with movement resistance levels that match your height and weight.

“Finally an elegant solution to the challenge of dynamic seating. Ex Chathedra's Lyrical Chair accomplishes dynamic postural sitting through insightful design and quality craftsmanship. The tilting platform subtly elicits a neuromuscular balance response from the core muscles, simultaneously minimizing tightness and resulting in effective muscle conditioning. In 30 years of consulting on ergonomics and patient care, this is the most effective design I have seen.”
