Effortless movement

Initiating movement when seated on Actulum is effortless. Tilt forward or lean back, and the curved wooden runners create a pendulum movement responding to your body’s natural inclinations. Actulum features a slim backrest with a flexible joint, which purpose is to accommodate the largest possible number of sitting positions. The upholstered back and seat cushions provide a soft surface, without taking away from the chair’s airy expression.
