Cosm Workchair Low Back - Nightfall

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.

Cosm’s ergonomic support goes beyond mechanics. The frame and fabric suspension work in tandem with the Auto-Harmonic Tilt. The continuous suspension material, Herman Miller’s new Intercept™, forms to each person’s unique contours, delivering dynamic, uninterrupted support. Intercept delivers thermal comfort while standing up to years of use. The hourglass-shaped suspension attaches to the frame, creating areas of high- and low-tension that provide comfort and support where it is needed most—regardless of body size or position in the chair.
The chair designed for everyone.

Manufactured by Herman Miller, USA
