Aeron Size B Office Chair by Herman Miller was designed by Don Chadwick and Bill Stumpf as the mid-range size within the landmark Aeron chair family — the most widely specified and imitated task chair in modern office design history. Size B suits the majority of adult users, and its Pellicle mesh seat and back, PostureFit SL lumbar support and comprehensive adjustment range have made it the default Aeron specification in most general office fit-outs, from individual desk purchases to large-scale corporate workplace rollouts.

The Aeron Size B's breathable mesh construction distinguishes it from conventional foam-upholstered task chairs, distributing seated pressure evenly across the mesh surface while allowing air to circulate freely — a genuine comfort advantage during long working days, particularly in warmer climates or poorly ventilated office environments. Its adjustable arms, seat angle and tilt tension allow individual users to fine-tune the chair precisely to their own working posture, supporting genuine full-time desk use rather than occasional or short-duration seating. Herman Miller's rigorous testing standards ensure the Aeron range meets demanding commercial specification requirements across its full twelve-year warranty period.

Architects and interior designers specifying the Aeron Size B for corporate office and home-office environments will find the DWG drawing and CAD block essential for workstation layout and clearance planning. The 3D model and Revit family support BIM-accurate spatial documentation. The standard specification for any project requiring the definitive modern task chair. Its consistent adjustment range across all three Aeron sizes simplifies procurement for offices seeking a single cohesive task chair standard.

Available as a 2D DWG drawing, 3D model and Revit file.
