Designed to Lift You Up.
The Cosm's distinctive leaf arms flex naturally with your movements, providing support exactly where you need it. The airy, open form is the result of years of research into how people actually sit and the answer was a chair that works with your body, not against it.

Yes, this is a 100% genuine Herman Miller Cosm.
