The executive office chair, designed inspired by the strength of the Ronins, individuals who aim to bring change and innovation in management with their free spirit, motivates today's visionary, open-minded, and determined leaders with its powerful and confident form. The Ronin stands out with its automatic synchronous mechanism, which adjusts the backrest firmness according to the user's body weight, and its backrest structure, which allows flexibility up to 20° and provides five-point adjustment, offering support for the upper body in various seating positions. The weight-sensitive automatic synchronous mechanism, which allows the seat to move along with the backrest and tilt up to 6°, ensures an ergonomic seating experience by maintaining a balanced distance between your lower back and the seat surface.
