What's In It For You

Mirra 2 Chairs

Together in Motion

As work evolves, and we become more active, flexing from individual to collaborative work in an instant, Mirra 2 moves with you, at one with your body. When you sit, Mirra 2 adapts to you instantly. Shift, and it dynamically supports even your slightest movements. By rethinking every part of a successful design, we advanced how Mirra 2 moves with you.

Hybrid Performance

The Mirra 2 Butterfly Back, with its exceptional responsiveness and intuitive feel, results from inventing a method for merging a fabric layer with polymer veins to create an intelligent support structure. This hybrid structure, shaped for dynamic support, keeps your body in healthy alignment.

The Classic Mirra Look, Evolved

Mirra 2’s reengineered TriFlex back maximizes the strength and flexibility inherent in its polymer material to provide dynamic support. The size, shape, and pattern of holes in the backrest have been carefully calculated to create zones of support that encourage healthy seated movement. And because there is no textile layer, the TriFlex back can meet more rigorous cleaning protocols.

Healthy Alignment

PostureFit sacral support is designed into both Mirra 2 back options to support you at the base of your back, the sacrum, so your spine stays properly aligned. Healthy alignment—the opposite of slouching—keeps spinal fluid flowing, which helps prevent back and neck pain.

Breathable Comfort

Ingenuity is apparent in a seat design that takes full advantage of our AireWeave suspension material. Distributing your body pressure evenly as soon as you sit, this material allows airflow to prevent heat buildup and keep you cool.

Balanced Feel

A reinvented Harmonic tilt creates a smooth and balanced feel as you move from one posture to another. Designed to mimic your natural pivot points at the ankles, knees, and hips, it helps you maintain a healthy posture.

Lean Profile

The lean design of Mirra 2 brings a sophisticated profile and visual lightness to any space. An emphasis on performance is visible. The chair’s individual components and their function are apparent and celebrated, and vary accordingly in material and appearance.

Multiple Choices

Added selections for textile and back colors along with new options for base finishes increase your range of choices.

Essential Molecules

The quest to make every molecule count led to a dematerialized design—less material used intelligently for a chair that is more responsive to your body, and more responsible to the earth.

Reduced Footprint

Compared to the original design, Mirra 2 contains over 70 percent more recycled content, largely the aluminum in its new tilt design. More recycled content and a 10-pound weight reduction cut the chair's carbon footprint by about 25 percent.

Lasting Legacy

Building on its legacy as the first office chair developed from the ground up using Design for the Environment (DfE) principles, Mirra 2 moves sustainable design forward by advancing the use and reuse of materials. Recycled aluminum accounts for about 40 percent of Mirra 2's content, and the chair's base is a prime example of this ingredient. Aluminum in the base's H-Alloy version brings an added benefit: a beautiful finish achieved without using additional coatings.

Design Story

Rethinking an Original

Ten years and over 1.5 million chairs later, the designers of Studio 7.5 believed it was time to evaluate and, if necessary, rethink their original design of the Mirra chair. For one thing, they noted, work is evolving. People move, and the more they're in motion, the more they need support that moves with them.

A Personal Chair

Precisely because of the new agile way people work today, the designers found the idea of a highly individualized personal chair is still valid. While Studio 7.5 retained the athletic attitude and intuitive adjustments of the original, they advanced the material and form of this idea in virtually every aspect of Mirra 2.

“Every Molecule Counts”

In redesigning Mirra, as in all their work, the mantra at Studio 7.5 was "every molecule counts." By this they mean a close examination of every element is essential to using the least material possible while also advancing performance.

Testing Ideas, Full-Scale

Using full-scale models, the designers of Studio 7.5 test the validity of a design and its component parts. For Mirra 2, every piece received this tactile, real-world treatment until the most elegant solutions emerged.
