Cosm Chair

Sit in Cosm, and you just might forget you’re sitting in a chair at all. Its sophisticated ergonomic design instantly responds to your body, movement, and posture to provide natural balance and total support.

The designers knew, even when working on predecessors like Mirra, Setu, and Mirra 2, that the ideal chair would provide a smooth feeling of natural balance. “You should have a chair that allows you to change postures as easily as possible,” Roland says. “You can only do that with a chair that is correctly adjusted, so we wanted to build a chair that does that part for you.”

A tilt is to a chair what a transmission is to a car, and like transmissions, some are manual, and others, such as Cosm’s, are automatic. With other self-adjusting models, the chair decides how you should sit by forcing the body to conform to the tilt’s movement. Cosm’s Auto-Harmonic Tilt puts the person first and responds to them—no matter their posture—providing a balanced recline and personalized comfort. Studio 7.5 and Herman Miller perfected the self-adjusting tilt by inventing a complex, finely tuned mechanism. Accounting for the sitter’s vertical force—which is always in flux—the gears within the tilt move the fulcrum along a leaf spring to automatically adjust the chair’s tension.
