Designed for Constant Motion
The Mirra 2 was designed by Studio 7.5 in Berlin for people who never sit still. Its Loop Spine provides torsional flex, allowing you to stretch and reach laterally without leaving your chair. The Harmonic 2 tilt creates a smooth, balanced recline that responds naturally to your body weight. First introduced in 2003, redesigned in 2014, and still one of the most awarded ergonomic chairs in production.
Butterfly Suspension Back
The Butterfly back uses a single piece of flexible polymer that conforms to your spine as you move. It provides full-back support while allowing air to circulate freely, keeping you cool throughout the day. The suspension distributes your weight evenly across the entire back surface, eliminating pressure points that cause discomfort during long sessions.
Harmonic 2 Tilt
The Mirra 2's Harmonic 2 tilt mechanism is widely considered the smoothest recline of any Herman Miller chair. It provides a balanced, natural feel as you shift between upright and reclined postures. Combined with a 3-position tilt lock and adjustable tension, you can set the chair to match exactly how you like to sit, whether you prefer an upright posture for focused work or a relaxed recline for reading and thinking.

Frequently Asked Questions
The Mirra 2 and Aeron are both premium Herman Miller chairs, but they suit different preferences. The Mirra 2 is lighter (19kg vs 23kg), has a smoother recline (Harmonic 2 tilt), and offers torsional flex for lateral movement. The Aeron has PostureFit SL (dual-pad sacral support), 8Z Pellicle mesh with 8 tension zones, and comes in three sizes for a more precise fit. If you prefer a dynamic, responsive chair that moves with you, the Mirra 2 is the better choice. If you want maximum spinal support and a chair you can set and forget, choose the Aeron.
Yes, this is a 100% genuine Herman Miller Mirra 2. We source our chairs as international parallel imports, which means they are not supplied through the standard Australian authorised-retail channel. Because of this, serial-based registration with Herman Miller is not available. Warranty support for this chair is provided directly by Chair Dinkum for 12 years.
Chair Dinkum provides a 12-year warranty on all Mirra 2 chairs we sell. This covers the frame, tilt mechanism, gas lift cylinder, base, armrest structure, and suspension materials under normal commercial use (8 hours per day, 5 days per week) or 24/7 use. If any covered component fails within the warranty period, contact us directly and we will resolve it.
Yes. The Mirra 2 is delivered fully assembled in protective packaging. You simply open the box, remove the packaging, and place it at your desk. No assembly, no tools, no waiting. The chair is ready to use immediately.
The Butterfly Suspension back is a single piece of flexible polymer that conforms to your spine and distributes weight evenly. It provides a slightly softer, more enveloping feel. The TriFlex polymer back uses three distinct zones of flexibility that allow independent movement in the upper, middle, and lower back. Both options promote airflow and support your spine as you move. This listing features the Butterfly Suspension back.
The Mirra 2 suits people who move frequently while working, shift between tasks, and prefer a responsive chair that adapts to their posture changes. It is particularly well suited to people who find the Aeron too rigid, people who want the smoothest recline available, and those who value lateral flexibility for reaching and stretching. It supports up to 159kg and fits a wide range of body types in a single size.
