The Chair for You

Its sophisticated ergonomic design instantly responds to your body, movement, and posture to provide natural balance and total support.


Meet Cosm

The sophisticated ergonomic design of the Cosm office chair by Studio 7.5 gives you a new experience of comfort—anywhere you work.


Cosm’s Auto-Harmonic Tilt, Intercept suspension, and flexible frame work together to give you a feeling of weightlessness.

No Adjustments Necessary

The Auto-Harmonic Tilt instantly and automatically provides balanced support and movement, depending on your body and posture.

Seamless Support

Breathable and temperature-neutral, the Intercept suspension has a continuous form that eliminates the gap between the seat and back. It conforms to each person's body to provide dynamic spinal support.

Comfort in Motion

The flexible frame is thin but strong and feels nearly nonexistent. It offers support while flexing so you can comfortably move your upper body.
