For 10 years, the Mirra chair has been a staple in offices worldwide. In that time, the way we work has changed and technology has made great stride. The Mirra 2 is the latest addition to Herman Miller’s premier task seating family; using new production methods, they’ve has crafted a chair that belongs in the modern office.

Partnering with Studio 7.5, Herman Miller deconstructed Mirra from the top down. Taking a critical eye to every aspect of its construction, they revised and rebuilt a task chair that lives up to the Mirra name. When you sit down in the Mirra 2, you’ll experience:

  • Dynamic Support: A completely reinvented Harmonic tilt that provides balanced support when you switch positions.
  • Superior Alignment: Mirra’s Butterfly Back, a hybrid design of polymer veins and merged fabric layers, means intuitive ergonomic response for a healthier workday you don’t have to work for.
  • Lightweight Construction: Carrying on Herman Miller’s commitment to environmental responsibility, the Mirra is is 22 percent lighter than it’s predecessor and 25 percent smaller.

About the Designers: Studio 7.5

“We define not only how a chair looks but how it performs, even down to the characteristics of the tilt. We're very involved with its physical behavior, because beauty is not only what you see, it's also what you feel.” — Studio 7.5, Designers of the Mirra Chair

After the international triumph of the Aeron chair in 1994, Herman Miller was looking for a way bring the benefits of ergonomic design to a wider audience by designing a high-performance chair at a lower price, with fewer adjustments and a wider fit range, plus an environmentally-sustainable design. They sought to design an office chair that would provide maximum benefits using minimal materials.

The five designers comprising the Studio 7.5 Group (Claudia Plikat, Burkhard Schmitz, Nicolai Neubert, Carola Zwick and Roland Zwick) were hired to envision a chair that would react to what the person sitting in it did — to design an office chair that would become a second skin, or shadow, of the sitter. This idea evolved into the concept underlying the Mirra chair: “Passive Adjustivity” — just sit in it and it fits! The earth-friendly Mirra was also the world’s first chair to be designed from its inception according to cradle-to-cradle principles.

Following the success of the Mirra, the Studio 7.5 Group began work on a new, multi-purpose task chair called the Setu with a “Less is More" aesthetic: nothing to tilt, nothing to adjust. The chair would be engineered with embedded ergonomics so the sitter and chair would move as one — form and function working together in harmony.


About the Manufacturer: Herman Miller

Founded in 1923 and recognized today throughout the world as an innovator in office and residential furniture design, Herman Miller has been ranked since 1986 among the top ten in Fortune Magazine’s annual list of the 500 most admired companies. Their pioneering research into producing environmentally responsible furniture has earned them GreenGuard Indoor Air Quality certification for most of their products. Aesthetically, many of Herman Miller’s iconic designs, particularly from the 1940s and 1950s, are valuable collector’s items and on permanent display in museums such as the New York Museum of Modern Art (MoMA) and the Smithsonian Institution.

In 1933, new furniture designs created by Herman Miller designer Gilbert Rohde exhibiting the smooth lines and unembellished shapes of the emerging mid-century modern furniture style were exhibited at the Chicago World’s Fair. In 1944, Rohde’s successor George Nelson designed such enduring icons as the Platform bench, and was famously responsible for teaming the company with such influential design artists as Alexander Girard, Isamu Noguchi and Charles and Ray Eames. Charles Eames, widely regarded as a genius in contemporary furniture design, produced one of Herman Miller’s most successful products in 1956, the elegant Eames Lounge chair. In 1994, Don Chadwick and Bill Stumpf introduced a new office chair called Aeron (derived from the word aeration, which describes how the mesh suspension promotes comfort), which became an immediate worldwide success and earned a spot in the New York Museum of Modern Art (MoMA) as well. Today, Herman Miller continues to attract world-famous designers like Jeff Weber, Jerome Caruso, the Studio 7.5 Design Team in Berlin, Yves Béhar, Mark Goetz and many more.

If the purpose of design is to solve problems, and the relationship between design and business is synergistic, then Herman Miller today continues to be in the vanguard of design as a fundamental part of strategic planning.
