Total back support

Many of Mirra’s adjustments are passive, requiring no effort to operate. The patented TriFlexTM back, for example. This one-piece, pliable backrest naturally flexes and adjusts to your shape, height and motion. The backrest features a passive PostureFit® contour for superior lower-back support and comfort when you sit upright or forward at a computer.

To support your entire back as you move throughout the day, the various geometric shapes in the TriFlex back create flex zones in the thoracic, lumbar and sacral regions.
