Environmental Product DeclarationClassic Aeron Chair Design StoryClassic Aeron’s functionality shows through, contributing to a distinctivelook that invites you to sit and experience the chair for yourself. Fromthe transparency of the Pellicle suspension material to the chair’scurvilinear lines, classic Aeron was designed around people, withBill Stumpf and Don Chadwick creating an aesthetic all their own. It’sno wonder the chair was added to the permanent collection of theMuseum of Modern Art even before the first one was sold.Every material, every mechanism on classic Aeron advances the art andscience of seating. The Pellicle seat and back distribute your weightevenly, eliminating pressure points and heat buildup. The Kinemat tiltallows you to recline fluidly, as your body pivots naturally at the hips,knees, and ankles. And PostureFit puts support where you need itmost while seated—at the base of your spine.Environmental DataCompany DescriptionSupplier Support53% Recycled ContentHerman Miller creates inspiring designs to help peopledo great things at work, for learning, for wellness, at home,wherever people are.

Our Design for the Environment team appliesenvironmentally sensitive design standards to both new andexisting Herman Miller products, and goes beyond regulatorycompliance to thoroughly evaluate new product designs inkey areas: Material Chemistry and Safety of InputsWhat chemicals are in the materials we specify,and are they the safest available? DisassemblyCan we take products apart at the end of theiruseful life, to recycle their materials? RecyclabilityDo the materials contain recycled content, andmore importantly, can the materials be recycledat the end of the product’s useful life? Life Cycle Assessment (LCA)Have we optimized the product based on theentire life cycle?Returnable packaging is available for the classicAeron Chair.*Based on availability of recycling facilities.1

The EPD applies to all colors of the classic AeronChair with adjustable arms, tilt, aluminum base (both powdercoatedand polished base), casters, and suspension seat. The classic AeronChair without arms is excluded from this study.Raw Material Extraction and PreprocessingThe raw materials stage covers the extraction and production ofthe raw materials needed to manufacture the product. It includesthe processing of the extracted raw material to the point where itcan be made into a recognizable part, as well as transportationof the finished raw material to the part production factory.ProductionMaterials are converted into parts and assemblies and made intothe final product. This stage, often referred to as Gate to Gate,includes packaging of the final product and transport of parts andassemblies to the place of final product assembly and packaging.DistributionTransport of the product to the final customer, including retail andwarehousing. Herman Miller products generally ship directly fromthe manufacturing plant to the final customer and are not sent toretail or warehousing.UsageUse, maintenance, and regular cleaning of the product. Herman Millerseating products are generally cleaned with a dry or damp rag and donot typically require maintenance during their warranted lifetime.End of LifeEnd of life treatment of the product including landfill, recycling,waste-to-energy process, and transportation to the place of final disposalor recycling. We design our products to be easily disassembled andrecycled; however, in this study, our product was modeled using thenational average recycling values. As a result, more of our materials weremodeled as going to the landfill than should occur in actual practice.Herman Miller also offers programs to help our customers find homes fortheir furniture and materials at end of life.3
