Mirra 2 Stool

Summary

Designed with an “earth first” philosophy, the Mirra 2 Stool from Herman Miller is an agile, high-performing choice for those who frequently toggle between individual and collaborative work. Mirra 2’s Loop Spine provides torsional flex, allowing you to stretch and reach laterally, while the Harmonic 2 tilt provides a smooth, balanced feel as you recline. Passive PostureFit sacral support prevents slouching and promotes proper spine alignment. Personalized ergonomics come from a variety of features, starting with two back options—Butterfly and TriFlex. Both options promote airflow so you stay cool, no matter how much you move. The FlexFront seat offers depth adjustability to properly support your thighs as you sit, and the AireWeave2 suspension seat is temperature neutral, so heat doesn’t build up as you sit. A sustainable choice, the Mirra 2 is made partly from recycled materials.

Highly responsive and lighter than ever

Named for the way it mirrors the body’s movements, Mirra 2 balances immediate comfort and personalised ergonomics in one sophisticated design that can have a professional or playful aesthetic, depending on the colour palette. Designed with an “earth first” philosophy, it’s an agile, high-performance stool for people who toggle between individual activities and collaborative work.

Moves naturally with you

Support for seated movement starts with a flexible yet supportive design that allows your body to move naturally and freely. Mirra 2 has torsional flex, allowing you to stretch laterally, and a tilt that creates a smooth and balanced feel as you change postures, regardless of your build. Its sacral support promotes proper spine alignment. An inventive use of materials keeps your body supported and cool. It’s this combination of dynamic support and personalized ergonomics that make Mirra 2 exceptional. 

Every molecule counts

Winner of multiple sustainability awards, Mirra 2 was the first office chair developed from the ground up with environmental responsibility in mind. Since it was introduced in 2003, we’ve made the chair 30 percent lighter and we’ve converted the chair’s nylon base and spine to 100 percent recycled content, further reducing the chair’s carbon footprint.

Versatile and innovative CMF

As performance defines the look of Mirra 2’s components, the color of those components allows significant options for defining the overall aesthetic of your chair or stool, offering everything from clean, monochromatic to bold color blocking. A modern, inspiring color palette for textiles, back loop and spine, and base finishes offer flexibility and encourage personalization.

The secret behind Mirra 2’s responsiveness

How exactly is Mirra 2 able to mirror your natural movements, supporting your body at every twist and shift? Through a combination of innovative design and special materials.

Butterfly Back

Made from a combination of a fabric-and-polymer backrest and a self-contouring seat material that acts like a suspension membrane, the Butterfly Back is mapped to your body’s anatomy. The result is an ultra-responsive chair that conforms to your shape and provides custom support for your body as it eliminates pressure points.

TriFlex back

The polymer-only TriFlex back has the same self-contouring suspension seat material as the Butterfly Back and the same zones of support created by the size, shape, and pattern of the perforations. Because it doesn’t have any fabric, the TriFlex back meets more rigorous cleaning protocols. 

Harmonic 2 tilt

Made possible by kinematic technologies designed around the body’s natural pivot points, the Harmonic 2 tilt enables the chair to move in tandem with your body through a range of postures, keeping you in balance without stressing any part of your body. 

Loop spine

Because it connects to the chair in only two areas, the loop spine provides torsional flex, allowing Mirra 2 to move and bend with you as you stretch and reach laterally. It enhances the chair’s responsiveness and gives you a greater range of supported movement. 

AireWeave

The elastomeric AireWeave suspension seat conforms to your shape, distributes your weight evenly, and keeps heat from building up as you sit, regardless of how active you are. 

PostureFit

Our patented sacral support, PostureFit supports your spine at its lowest point, the sacrum, and reinforces your pelvis, preventing slouching and fatigue while you sit.

Meet the family

Mirra 2 work chairs and stools are both available in two back options, either the flexible TriFlex back or the ultra-responsive Butterfly Back. Stools extend the Mirra 2 design into any setting where seated and standing collaborators benefit from being at a common eye level.
