Adult office chair Mirra 2

on casterswith armrestswith high backrest

Overview
Named for the way it mirrors the body’s movements, Mirra 2 balances immediate comfort and personalised ergonomics in a refined office design. Engineered for users who alternate between individual focus and collaborative work, the chair is lighter than earlier models (approx. 30% reduction vs original) and integrates increased recycled content to reduce environmental impact.

Key benefits and uses

• Dynamic support that follows seated movement and adapts to frequent posture changes common in modern workspaces.
• Personalised ergonomics across a wide range of body types through adjustable mechanisms and targeted support zones.
• Breathable materials and suspension seat to distribute weight evenly and reduce heat buildup during prolonged use.
• Sustainable design with reduced material use and recycled-content structural components.
• Suitable for individual workstations, collaborative areas and touchdown settings; available as chairs and stools.

Main features

• Torsional flex and Loop Spine for lateral stretch and responsive movement.
• Two back options: Butterfly Back (fabric + polymer) or TriFlex Back (polymer-only) to suit hygiene and aesthetic requirements.
• Harmonic 2 tilt system that follows natural body pivot points for balanced support across postures.
• AireWeave elastomeric suspension seat that conforms to the body and improves ventilation.
• PostureFit sacral support to stabilize the pelvis and reduce slouching and fatigue.
• Reduced weight compared with earlier generations and use of recycled nylon in key structural parts.
• Wide CMF options (colors, materials, finishes) to match professional or playful interiors.
• Available as work chairs and stools across the Mirra 2 family.

Design and technology details
Mirra 2’s responsiveness is achieved by combining a self-contouring suspension seat, zoned support via TriFlex perforations or mapped Butterfly fabric-and-polymer back, a Loop Spine for torsional flexibility, and the Harmonic 2 kinematic tilt that moves the chair around natural pivot points. PostureFit sacral support reinforces pelvis alignment. Iterative redesign reduced overall weight and increased recycled content in structural components to improve lifecycle impact.
