A Wellback kneeling chair not only makes sitting fun, but more importantly, it may improve health and productivity. Originally developed by Karo in 1986, the design is based on sound ergonomic principles. The underlying principle of a kneeling posture chair is to maintain an ‘open’ pelvis while you are sitting. This reduces the strain in your lower back that normally occurs when you sit on a conventional chair. Is a kneeling chair suitable for me?
