Free pickup from our Fairfield VIC showroom, by appointment.
The Cosm was designed by Berlin’s Studio 7.5 for Herman Miller and first shown in Milan in 2018.
Its Auto-Harmonic Tilt reads your weight and posture and sets the recline tension by itself, so there is no tension knob. The Intercept suspension runs in one continuous piece from seat to back, with no gap behind the lower spine.
This is the low-back Cosm in Nightfall, a deep navy. The whole chair is the one colour: frame, mesh, arms and base. Both the seat and the arms are height-adjustable, and it was made in the USA in 2022.
A chair that sets itself to whoever sits in it.

About Herman Miller ▾
Founded in 1905 in Zeeland, Michigan, Herman Miller became one of the world's most important furniture makers by partnering with visionary designers. Its long-time design director George Nelson brought in Charles and Ray Eames and Isamu Noguchi, and the company later reinvented office work itself with the Action Office (1968), the origin of the modern workstation. Herman Miller pieces are built for commercial use and made to last decades.
Famous designers: Charles & Ray Eames, George Nelson, Isamu Noguchi, Bill Stumpf & Don Chadwick
