* Passive PostureFit� camber shape at the base of the back gives healthful, comfortable support to the lower back below the beltline
* Harmonic tilt creates pivot points at the hip, knee, and ankle
* AireWeave� suspension follows the contours of the body and provides aeration
* Adjustable arms and tilt limiter
* FlexFront� fully adjustable seat depth
* TriFlex polymer back support with fully adjustable lumbar support
* Foam-free upholstered seat
* 5-star base with your choice of standard carpet casters, hard floor casters, or deep carpet casters
* Weight capacity is tested as approximately 300 pounds
* Minimal assembly required
* Formerly known as part number MR122AAMAJ

Harmonic Tilt�

* Pivot points are user's hip, knee, and ankles for easy, natural movement and control
* Backrest and seat move in proper relation for correct support in all positions
* Advanced spring technology allows for equal support throughout the wide, 26 degree tilt range

TriFlex�

* Pliable, elastic material supports the user's entire back
* No adjustments necessary - geometric design creates three flex zones that conform to anyone's size, posture, and movement
* Camber contour at base forms a passive PostureFit support and helps maintain proper spinal alignment
* Breathable construction allows heat to escape and keeps sitters cool

Casters

* Three different caster options can accommodate any style of flooring:
o Standard casters � work well on most low pile office carpets (wheels 2 �� diameter)
o Deep-carpet casters � loose design and larger size (3� diameter) help the user avoid snags and move easily across thicker carpets
o Hardwood casters � thin rubber coating prevents damage to flooring and provides greater traction on non-carpeted surfaces

DESIGN STORY

Studio 7.5 To create the Mirra chair, Herman Miller teamed with Studio 7.5, a German design firm.

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.

They consider themselves 'the grandchildren of the Eameses' and, like those pioneering designers, they are experts at observing how workers interact with their environments and finding ways to make that interaction more natural. Sharing a genuine passion for seating, they know seating as a science and work to bring it to another level.

Rather than relying on any individual in the firm, Studio 7.5 works as a team, without titles or hierarchy. The Mirra chair is a product of their collective imagination, talent, and persistence--along with a willingness to break the mold in order to create a chair that sets a new standard for comfort, fit, balanced ride, and visual refinement in its price range.

Studio 7.5 envisioned a chair that reacts to what people do. Part of the concept was to make the chair like a second skin, like a shadow of the sitter.

From this concept, Mirra's passive adjustability was born. From the TriFlex� back to the AireWeave� seat suspension to the Harmonic� tilt, Mirra does just what Studio 7.5 worked to achieve: Just sit on it, and it fits. There are only a few adjustment controls, and they are designed to be very intuitive.

Mirra features common materials applied in original ways--such as the elastomeric seat suspension and molded polymer back that are used instead of foam and fabric. The relationship between materials and technology was optimized to achieve maximum performance with minimal materials.

User testing, benchmarking, focus groups, tilt performance studies, and other methods were used to ensure the chair meets customer needs and provides advanced ergonomic performance. For example, research over the years has shown that the biggest concern users have is back support. In fact, back issues account for the second highest number of work illnesses. The designers took this to heart and focused on the back as an area of differentiation.

Herman Miller and Studio 7.5 also used results from the Civilian American and European Surface Anthropometry Resource (CAESAR) study, which surveyed body measurements of people aged 18-65, using the latest 3-D technology. Data from the study--the first full-body, 3-D surface anthropometry survey of the U.S. and Europe--helped ensure the chair fits people from the 5th percentile woman to the 95th percentile man.
