Herman Miller Mirra Office Chair

Product information

Offering superb support while stripping away material to create a streamlined finish, the Mirra is a new reference point for performance, aesthetics and sustainable design.

The striking one-piece frameless backrest consists of a polymer pierced with 567 geometric shapes, creating three flex zones. Each zone provides an appropriate level of flexibility for the ideal level of ergonomic support and natural adjustment. This durable material maintains its strength and responsiveness throughout the years.

Thanks to unique design features, this chair adapts naturally to your body type. PostureFit supports the way your pelvis tilts forward naturally, ensuring that your spine stays aligned to avoid back pain and allow you to sit for hours in complete comfort. Along with PostureFit, the Harmonic tilt feature lets you effortlessly move through the chair’s 28-degree recline range.

Designed to support your back while you work, the TriFlex backrest is pliable and elastic, effortlessly accommodating individual sizes, postures and micro-movements. Working with Tri-flex, a motion suspension-control AirWeave seat balances your weight perfectly, with breathable mesh cooling your body temperature. For further sitting ease a FlexFront seat edge ensures that there's never a gap between the seat and back, by adjusting the depth of the seat without moving the seat pan.

This chair is also an environmentally friendly option: a third of Mirra is made of recycled materials, and when its useful life is over, it is 97% recyclable.
