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.

Actulum is available in a natural or black finish, and a wide range of upholstery fabrics and colors. The wooden runners are made from layers of beech and ash plywood, which are laminated and given their characteristic shape through the application of heat and pressure. The floor runner and armrest are made from one single piece of pressed plywood, creating a distinct visual profile while ensuring smooth movements.

  • Materials

    Actulum is made from top quality beech ply wood from European forests. The ply wood is treated through an iterative molding process where several veneer layers are combined and glued. Through the application of combined heat and pressure, the layers are given their characteristic shape, making our Actulum stand out from the crowd. All wooden parts are flexible and strong, ensuring a sitting experience that is never static. For a beautiful finish, our ply wood is covered with ash top veneer, manually sanded and coated with water-based, non-toxic lacquers.
