A new movement in active sitting

From the same Aeris philosophy behind our innovative Swopper and Muvman chairs, the award-winning Numo is designed to encourage natural movement by adapting to the way you sit.

Its kinematic system has four flex points that allow you to swing both forward and backward with subtle motion, keeping you supported and engaged—even for extended work sessions. The seat shell comes in five colors and can be paired with natural oak legs or a steel sled base.

From conference room to lounge to home office, the timeless and versatile Numo makes a striking statement in any setting.

Sled base

The Numo sled base, with its matching seat color, can be used both indoors and outdoors. This versatile chair is perfect for common areas, conference rooms, and the home office as well as terraces, balconies or gardens.

Wooden legs

Numo with wooden legs has the same oak wooden leg base with a die-cast aluminum kinematic finish for all the seat colors. From conference room to lounge to home office this chair makes a striking statement. 

Keep it moving

Engaging in healthy, energy-bringing movement throughout the day keeps your body engaged and your mind focused. Thanks to the patented kinematics that connects the seat to the base, Numo adapts to the way you want to sit by providing subtle motion. The kinematic mechanism with crossed lever arms is visually reminiscent of the spine’s disc structure and supports the body's natural need for movement.
