Details
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.

Design Story
Founded in 1905 in Michigan as a traditional furniture company, it transformed in the 1930s under the leadership of D.J. De Pree. Instead of playing it safe with conventional styles, the company leaned into modernism, collaborating with visionary designers who would go on to define an era.
The turning point came through partnerships with figures like Charles Eames and Ray Eames, whose molded plywood and fiberglass chairs became icons of mid century design. George Nelson, the company’s design director, helped establish a cohesive and forward thinking identity, bringing in talents like Isamu Noguchi.
Over time, Herman Miller built a reputation for blending aesthetics with function. That philosophy carried into the late 20th century with innovations like the Aeron Chair, which redefined office seating and became a symbol of early tech culture.
Today, Herman Miller remains a global design leader, balancing heritage with innovation. Its pieces are not just furniture, they’re cultural artifacts that quietly signal taste, whether in a Silicon Valley office or a carefully curated living room.
