Like it was made just for you

Responsive to your body’s natural micro-movements, Cosm provides support and comfort the moment you sit. A combination of dynamically conforming suspension material, a super flexible frame, and move-with-you Auto-Harmonic Tilt technology, offer instant, adjustment-free comfort.

Breathable and temperature-neutral, the continuous form of Cosm’s Intercept elastomeric suspension eliminates the gap between seat and back. This means a more responsive fit that provides snug but flexible comfort for a range of bodies—no fidgeting necessary.

A strong but flexible frame provides support without hindering movement; in fact, it encourages a seamless range of motion so you barely realize it’s there. And Cosm’s elastomeric Intercept suspension—aka, the comfortable springy material on its back and seat—is breathable and temperature-neutral for all.
