Herman Miller Mirra 2 Butterfly™ Suspension

The Herman Miller Mirra 2 is the chair Berlin's Studio 7.5 designed for people who do not sit in one position for long. Its defining feature is the Butterfly Suspension back, and it exists to solve a real trade-off. A pure mesh back breathes and flexes but gives you almost no shaping. A moulded polymer back holds a shape but is dead and warm against your spine. The Butterfly back does both at once: a flexing polymer layer supplies the structure and the zoned support, and a fabric layer over it distributes pressure and keeps it breathable.

Behind that sits the Loop Spine, which attaches to the chair at only two points and is otherwise free to twist, so the back follows you when you turn to a second monitor instead of resisting. The Harmonic 2 tilt is built around the body's natural pivot points, so recline feels balanced rather than like being tipped. The Mirra 2 suits people who move between focused work, calls and collaboration all day, who run warm and want a back that breathes, and who want an adjustable chair rather than an automatic one. It is not the right chair if you want a headrest — Herman Miller does not make one for the Mirra 2 — or if you specifically want the give of an all-mesh back, because the polymer layer is more structured and firmer than mesh. Studio 7.5 redesigned the original 2003 Mirra, and the result is about 30% lighter than the chair it replaced.

• Butterfly Suspension back — flexing polymer layer with a fabric layer over it for zoned, breathable spinal support.
• Loop Spine connected at two points only, giving torsional flex for side-to-side movement; Harmonic 2 tilt aligned to the body's pivot points.
• AireWeave elastomeric suspension seat that conforms to your shape and moves heat away instead of trapping it. PostureFit sacral support is standard.
• Seat height 37.5–56.5 cm across cylinder options; seat depth 41.3–45.7 cm on the adjustable seat.
• Overall dimensions 106–111 cm high, 67–79 cm wide depending on arm configuration, 67 cm deep.
• Arm height 15–29 cm on fully adjustable arms, or 21 cm fixed; armless is also produced.
• Nylon base and spine are 100% recycled content, part of the redesign that made the Mirra 2 markedly lighter than the original.

The Mirra 2 you buy here is genuine and locally supported. We deliver across Australia and New Zealand. Try it at our Sydney (South Granville) or Melbourne (Nunawading) showroom — worth doing, because the Butterfly back feels quite different under you from the Aeron's mesh, and ten minutes in both settles the question faster than any spec sheet.
