Built on the same principles as the original, Mirra 2 from Herman Miller is designed to move with a user’s body. Its Butterfly Back, passive PostureFit system and independently adjustable lumbar support provide intelligent, dynamic support. A redesigned seat frame allows for the removal of foam under the front of the seat, further increasing breathability and comfort, while Harmonic™ tilt provides a smooth and balanced feel as people move from one posture to another, regardless of size.
