Features

A grouping of Nightfall navy blue, Canyon red, and Glacier light blue Cosm Chairs.

Colorful 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-color hues—Canyon, Glacier, and Nightfall.

Introducing 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, cozy resting place for your elbows. The sling design makes holding a phone or book natural and comfortable, and the angle of the arms means they don’t get in the way of a desk when it’s time to get back online.
