Haider was founded in 1948 by Eduard Haider senior. The permanent development work led to the addition of the name Bioswing - improve your life. Smart solutions for healthy sitting through a new culture of movement is the counter design to static sitting in the office. The BIOSWING seating system developed by Eduard Haider in cooperation with medical specialists, thearpeutists and universities was patented as early as 1983 and provides for more movement in the micro and macro area (sensorimotor function). This adaptive 3D seating system, designed according to the pendulum principle, has been perfectly adapted to the body logic and the movement spectrum of the seated person. The smallest movements are reflected like an echo, the seating system adapts harmoniously to the natural frequencies of 0.8 - 2.7 Hertz. Alternating tension and relaxation has a body-centering and balancing effect. As a result, both the brain and the nervous system are continuously stimulated, mental performance is increased and back health is positively influenced. Haider Bioswing seating systems are recommended by doctors, ergonomists and therapists, this high-quality seating furniture is tested and recommended by the "Aktion Gesunder Rücken e.V." AGR = Campaign For Healthier Backs. We at buerostuehle-4u recommend Haider-Bioswing - the excellent manufacturer of ergodynamic swivel chairs for more ergonomics and maximum mobility at the seated office workplace.
