ABOUT THE BRAND
Herman Miller — a century of human-centred design
Founded in 1905 in Zeeland, Michigan, Herman Miller has spent over a century designing furniture that improves the lives of those who use it. Long before ergonomics became an industry buzzword, Herman Miller was pioneering it — commissioning the landmark 1960 Propst 'Action Office' study and building the research infrastructure that would define modern workplace design.
Today, Herman Miller chairs are the benchmark against which all others are measured. Used in the world's leading architecture firms, technology companies, and design studios, they represent the intersection of scientific rigour and timeless aesthetics. When you sit in a Herman Miller, you're sitting on decades of human factors research.
ABOUT THE MODEL
The Cosm — the chair that adjusts itself
Designed by Berlin's Studio 7.5 and launched in 2018, the Cosm was built around a simple idea: the best chair is one you never have to think about. Its Auto-Harmonic tilt and Intercept suspension read your body weight and movement automatically, reclining with you the instant you sit down — no tension dials, no fiddling, no manual setup.
The result feels less like sitting on a chair and more like being supported by one. With its leaf-shaped arms, dipped-in-colour finishes and seamless mesh suspension, the Cosm brought a new kind of effortless comfort to the modern office — and quickly became a favourite in design studios and boardrooms alike.
