Like the original Mirra, which was introduced more than a decade ago, the leaner and lighter Mirra 2 Task Chair (2013) sports a spry, colorful form that belies an ingenious combination of passive and active seating adjustments that deliver hassle-free performance and lasting comfort to virtually all body types. The Butterfly Back™ yields to the occupant’s form to provide flexible and continuous support to the entire spine, with gradated cutouts that flex for greater movement and improved circulation, as well as an adjustable lumbar piece that supports your lower back. AireWeave 2 seat mesh evenly distributes weight and dissipates heat. An innovative passive Harmonic™ tilt mechanism enables the body to naturally recline by creating pivot points at the hip, knee and ankle. Allowing easy changing of seat depth, FlexFront® four-stage adjustment rolls the seat edge down to suit every user’s shape. A tilt tension adjustment covers a full range in nine revolutions, and an optional tilt limiter controls the amount of recline while maintaining good back support. Hard dual-wheel casters work well on and off carpet. This is the authentic Mirra 2 by Herman Miller. Made in U.S.A.
