How does the Mirra 2 compare to the original Mirra (Mirra 1)?

The Mirra 2 builds on the Mirra 1 by improving ergonomics, aesthetics, adaptability and sustainability. It introduces a smoother harmonic tilt mechanism, a redesigned Butterfly Back for better support and airflow, is lighter in weight (≈30% lighter), and uses updated materials and finish options.

What improvements in support and ergonomics does the Mirra 2 offer?

The Mirra 2 features enhanced dynamic support that moves with the user. The Butterfly Back combines polymer frame and flexible fabric to distribute pressure more evenly than the older rigid backrest. Also it includes improved tilt offer (harmonic tilt), seat-depth adjustment, and intuitive tilt and seat controls.

What sustainability benefits does the Mirra 2 bring?

Mirra 2 is designed with sustainability in mind: it uses up to 54% recycled content, is up to 93% recyclable at end of life, and uses fewer materials overall to reduce weight and environmental footprint.

What materials and build quality features does the Mirra 2 have?

The chair uses a blend of aluminium and high-grade polymers, including a polycarbonate backrest for breathability. The seat uses AirWeave™ 2 mesh of elastomeric and polyester fibres tested for durability. The armrests use foam pads with a urethane coating for resilience.

What range of adjustability does the Mirra 2 offer?

Adjustability includes seat depth, height/width/depth/pivot adjustments for armrests, tilt limiter, seat-edge adjustments, and independently adjustable lumbar support to cater for different user shapes and preferences.

What is the warranty for the Mirra 2 chair?

The Mirra 2 comes with Herman Miller’s 12-year warranty covering parts and labour.

Mirra 2 Review & Buying Guide

Mirra 1 vs Mirra 2

Head to Head

The Herman Miller Mirra 2 chair builds upon the solid foundation laid by the original Mirra (Mirra 1), offering a host of improvements in ergonomics, aesthetics, sustainability, and adaptability to meet the demands of modern work environments. While both chairs are designed to provide high levels of comfort and support for long hours of sitting, the Mirra 2 introduces several significant enhancements that make it a more refined and responsive seating solution.

Improved Support

One of the most notable differences lies in the chair’s responsiveness and dynamic support. The Mirra 2 has been engineered to accommodate the increased mobility of today’s office work. Compared to the Mirra 1, which was relatively static, the Mirra 2 features an improved “harmonic tilt” mechanism that offers a smoother and more balanced recline. This means the chair moves with the user in a more fluid way, promoting natural posture shifts and reducing fatigue. The redesigned Butterfly Back, which combines a polymer frame with a flexible fabric layer, better distributes pressure across the back and enhances airflow, offering more adaptive support compared to the rigid backrest of the Mirra 1.

Improved Look, Feel & Sustainability

In terms of aesthetics, the Mirra 2 boasts a sleeker, lighter, and more modern design. It is approximately 30% lighter than the Mirra 1, achieved through more efficient use of materials and a more refined frame. This not only contributes to a more minimalist visual appeal but also makes the chair easier to move and adjust. The updated colour palette and softer lines also make it more suitable for contemporary office settings.

Another significant improvement is the chair’s adjustability. While the Mirra 1 was already customisable, the Mirra 2 refines and simplifies these adjustments, making them more intuitive. For instance, the redesigned tilt limiter and seat-depth control are more ergonomic and easier to use. The addition of a more sophisticated FlexFront seat edge adjustment ensures users of different leg lengths can maintain proper circulation and comfort.

Sustainability is also a key area where the Mirra 2 outperforms its predecessor. Designed with the environment in mind, the Mirra 2 uses fewer materials and is made from up to 54% recycled content. It is also up to 93% recyclable at the end of its life. This makes it a better choice for organisations committed to reducing their environmental footprint without compromising on performance or style.

Mirra 2 Performance

Review

The Mirra 2 boasts a thoughtfully refined design, the result of extensive development by Studio 7.5. Every component has been carefully engineered to fit together seamlessly, giving the chair a cohesive, premium finish. There are no loose fittings or rattling parts – everything feels secure and well-constructed, contributing to an overall sense of durability and quality.

Constructed primarily from aluminium and high-grade plastics, the Mirra 2 remains relatively lightweight at approximately 19kg. The base, tilt mechanism, and armrest supports are made from aluminium, while the seat frame, backrest, and armrest shells are formed from a custom-moulded polymer. This material blend offers both strength and reduced weight, making the chair easier to manoeuvre.

The armrests feature foam pads coated with a urethane layer for added resilience. The seat mesh, known as AirWeave™ 2, is crafted from a blend of elastomeric and polyester fibres, offering both softness and robust durability. It has been tested to withstand up to 200,000 double rubs – a metric simulating the wear caused by someone repeatedly sitting and standing – confirming its suitability for intensive daily use.

Ergonomic flexibility is a key strength of the Mirra 2. It includes seat depth adjustment, which allows users of varying heights to achieve an ideal distance between the front edge of the seat and the back of their knees – a crucial factor for circulation and posture. The armrests also offer an exceptional range of height adjustment, accommodating users from shorter to taller statures with ease.

The chair’s backrest is equally impressive. Its polycarbonate construction ensures it is both supportive and breathable, encouraging airflow and comfort throughout the day. It is large enough to support the full length of your back while allowing for a wide range of movement. The flexible nature of the frame lets you shift positions naturally as you work, without sacrificing support.

A standout feature is the independently adjustable lumbar support. You can set different levels of support on each side of your lower back, catering to personal preferences or specific support needs. This, combined with the natural curvature of the backrest, delivers highly effective lower back support across a broad section of the spine.

Final Thoughts & Conclusion

The Mirra 2’s armrests also excel in both comfort and adaptability. With height, width, depth and pivot adjustments, they can be positioned precisely to suit a wide range of tasks and body types. This level of customisation ensures optimal arm positioning for typing, reading, or collaborative work.

Ultimately, the Mirra 2 stands out as Herman Miller’s most adjustable office chair to date. Its ergonomic versatility, high-quality materials, and sleek, contemporary design make it an outstanding choice for anyone seeking long-term comfort, adjustability, and style in their workspace.
