Herman Miller | Cosm Chair Collection

Sit in Cosm, and you just might forget you’re sitting in a chair at all. Its sophisticated ergonomic design sets a new bar for instant, personalized comfort, no matter who sat in the chair before you, how long you’ll be in it, or what you’ll be doing. The designers at Berlin-based Studio 7.5 knew, even when working on predecessors like Mirra, Setu, and Mirra 2, that the ideal chair would provide a smooth feeling of natural balance.

Cosm’s revolutionary Auto-Harmonic Tilt does just that— putting the person first and responding to them, no matter their posture—for total support. Available in three different back heights, as well as a stool, Cosm gives you a new experience of comfort—anywhere you work.


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. Or, mix and match any of the six colors on the suspension and frame.
