One of the most iconic office chairs in the world, the Herman Miller Aeron, has been a staple in workplaces for over two decades. Introduced in 1994, the Aeron quickly gained popularity for its innovative design and ergonomic features. Designed by Bill Stumpf and Don Chadwick, this chair revolutionized the way people sat at their desks, offering superior comfort and support.

As technology advanced and workstyles evolved, so did the need for a new kind of office chair. Enter the Herman Miller Cosm, introduced in 2018 as a response to changing workplace dynamics. Designed by Studio 7.5, the Cosm was created with a completely different approach from its predecessor. Instead of adjustable knobs and levers like those found on the Aeron, it uses an automatic tension mechanism that adapts to each individual’s body movements without user intervention.
