The Mirra 2 office chair has dynamic surfaces that respond to your slightest movements. It balances immediate comfort and personalised ergonomics.

Product Story

As work evolves, and we become more active, shifting from individual to collaborative work in an instant, we need tools designed to be as agile as our work style. To address this need, the designers at Studio 7.5 set out to create a high-performance chair that supports people who work in a constant state of motion.

Immediate Comfort and Personalised Ergonomics

Mirra 2 moves with you, at one with your body. When you sit, the seat and back adapt instantly. With dynamic surfaces that respond to your slightest movements and simple, intuitive adjustments to fine-tune the fit, Mirra 2 balances immediate comfort and personalised ergonomics in a single sophisticated design.

Support in Motion

Support for seated movement starts with a flexible, yet supportive chair that allows your body to move freely and naturally. Mirra 2`s Loop Spine provides torsional flex, allowing you to stretch and reach laterally, while the Harmonic 2 tilt provides a smooth, balanced feel as you recline.

Butterfly Back or TriFlex

Two back options help Mirra 2 work for a variety of people and applications. The Mirra 2 Butterfly Back results from inventing a method for merging a fabric layer with polymer veins to create a dynamic, hybrid structure. The TriFlex back meets more rigorous cleaning protocols because there is no fabric layer.


Both Mirra 2 back options offer passive PostureFit sacral support to prevent slouching and keep your spine properly aligned. And both are ventilated to keep you cool, as well as supported, no matter how active you are.

Form Celebrates Function

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 they vary accordingly in material and appearance.

Versatile Palette

While performance dictates the design of the chair`s components, their colouration allows significant options for defining your chair`s overall aesthetic. Added selections for textiles, back loop and spine colours, and base finishes offer flexibility and encourage personalisation.

Design story

Ten years after the Mirra chair was introduced - during which over 1.5 million chairs had been sold - the designers at Studio 7.5 believed it was time to evaluate and, if necessary, rethink their original design. 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.

Precisely because of the new agile way people work today, the designers found the idea of a highly individualised personal chair was 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.

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.

Building on its legacy as the first office chair developed from the ground up with environmental responsibility in mind, Mirra 2 moves responsible design forward by advancing the use and reuse of materials. 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 in order to use the least material possible while also advancing performance.
