The Mirra chair extends both the performance and aesthetics of ergonomic work seating to new levels. Introduced in 2003, Mirra resulted from years of careful research into fit, ride, tilt mechanisms, materials, aeration, adjustments, and design for the environment. The German firm Studio 7.5 designed Mirra, determined to create a chair that as much as possible mimicked the motions of a human body at work. Mirra's organic look, feel, and material content reflect the designers' dedication to advancing both the art and science of seating.

Composed of five designers--Claudia Plikat, Burkhard Schmitz, Nicolai Neubert, Carola Zwick, and Roland Zwick--Studio 7.5 has been involved for over 10 years in the design and development of products that improve the way people work.
