  • Description
  • Specification
  • 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.

    The Cosm chair is a sophisticated ergonomic design that instantly response to your body, movement and posture to provide natural balance and total support throughout the each users sitting experience without having to make any adjustments. 

    Key Features;
    - Cosms Auto-Harmonic Tilt, intercept suspension and flexible frame work together to give you a feeling of weightlessness. Cosm’s Auto-Harmonic Tilt puts the person first and responds to them, no matter what their posture is doing, to provide a balanced recline and personalised 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.
    Intercept Suspension provides breathable and temperature-neutral, the continuous form of this elastomeric suspension eliminates the gap between the seat and back, conforming to each person’s body to provide dynamic spinal support. 
    The thin but strong frame feels nearly non-existent and offers support while flexing so you can comfortably move your upper body.

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