Designed by Berlin-based Studio 7.5, Cosm is Herman Miller's first task chair with an automatic tilt. It also has the industry's first suspension armrest

Key Features:

Cosm's Auto-Harmonic Tilt:
intercept suspension and flexible frame work together to give you a feeling of weightlessness. Cosm's Auto-Harmonic Tilt puts the person first and responds to them, no matter what their posture is doing, to provide a balanced recline and personalised comfort. Studio 7.5 and Herman Miller perfected the self-adjusting tilt by inventing a complex, finely tuned mechanism. Accounting for the sitters vertical force, which is always in flux, the gears within the tilt move the fulcrum along a leaf spring to automatically adjust the chairs tension

The thin but strong frame feels nearly non-existent and offers support while flexing so you can comfortably move your upper body

Leaf Arms:
To offer as much comfort and ease as possible, Studio 7.5 created Cosm's Leaf Arms, which feature a soft but firm cradle design that provides a large, cosy resting place for your elbows. The sling design makes holding a phone or book natural and comfortable, and the angle of the arms means that they don't get in the way of a desk when it is time to get back online

Herman Miller are committed to sustainability in everything they do, the materials they use, the manufacturing processes and products recyclability 

Colourful Cosm:
Cosm is available in one hue from top to bottom to further cement the unity of the design and the sculptural quality of the chair. The designers collaborated with Herman Miller's materials team to land on three dipped-in-colour hues: Canyon, Glacier and Nightfall. It is also available in all Graphite finish, All Carbon Finish and Studio White with Mineral Base configurations
