What makes Wehlers different from other office furniture brands?

Wehlers documents every part of its circularity claim: a second-party verified carbon footprint as low as 15.1 kg CO2e, a guaranteed take-back program that closes the material loop, and B Corp certification since 2021, rather than relying on undocumented sustainability marketing.

Where can I find Wehlers' verified environmental data?

The full Product Environmental Footprint (PEF) methodology, material traceability, and industry benchmark comparison are on the Sustainability Transparency page, assessed by Quantified Impacts.

How does Wehlers handle furniture at the end of its life?

Wehlers operates a Guaranteed Take-Back program: full B2B orders are collected free of charge, and every chair is refurbished for resale or dismantled so its materials become new R.U.M. chairs.

Does Wehlers work with large enterprise clients?

Yes, including Novo Nordisk's Circular4Zero program and Elcon's DGNB-certified headquarters, with ESG and CSRD reporting data embedded directly into the procurement process.

How does Wehlers compare to specific competitors like Humanscale or Herman Miller?

Wehlers publishes direct, sourced comparisons: against Herman Miller Aeron, HÅG Futu, and the FIRA industry benchmark on the Most Sustainable Chair page, and against Humanscale's Ocean and Liberty chairs on the Wehlers vs. Humanscale page.

Why Wehlers

Wehlers makes one core claim: office furniture can be genuinely circular, not just recyclable in theory. Every part of that claim is documented and verifiable. This page is a single entry point to the evidence — material data, methodology, take-back mechanics, enterprise proof, and direct comparisons to other chairs on the market.

Verified, Not Marketed

The R.U.M. chair has a second-party verified carbon footprint as low as 15.1 kg CO2e, assessed by Quantified Impacts using the Product Environmental Footprint (PEF) methodology — a cradle-to-gate Life Cycle Assessment covering all 16 PEF-mandated impact categories under the EU PEF Category Rules for furniture. Full material traceability, the industry benchmark comparison, and certification detail: Sustainability Transparency. A shorter, consumer-facing version of the same data: Most Sustainable Chair?

Full-Circle, Guaranteed

Take-back is not an add-on service — it is how the material loop closes. Wehlers collects full B2B orders free of charge; every chair is refurbished for resale or dismantled so the materials go back into new R.U.M. chairs. Full mechanics, BREEAM credit mapping, and enterprise-scale terms: Take-Back & Circular Program.

Built for Enterprise

Large organizations get the same verified data embedded directly into quotes, order confirmations, and invoices — plus proof from real deployments, including Novo Nordisk's Circular4Zero program and Elcon's DGNB-certified headquarters. Full detail: Wehlers for Enterprise.

How We Compare

Rather than asking Wehlers to take its word for it, compare the data directly:

Most Sustainable Chair? — R.U.M. vs. Herman Miller Aeron, HÅG Futu, and the FIRA industry benchmark, with sourced citations.
Wehlers vs. Humanscale — a fact-based comparison of two B Corp-certified ocean-plastic chair programs: carbon footprint, recycled content percentage, and take-back.

Certified

Wehlers is a certified B Corporation — Scandinavia's oldest — with the commitment written into its articles of incorporation rather than treated as a marketing claim. Certification detail: B Corp Certificate.
