Herman Miller Aeron resale value — what your used Aeron is actually worth in 2026
If you've got Aerons sitting in storage, on a clearance project, or on the floor of an office that's relocating, this is what they're actually worth in 2026. Numbers are from our live UK buyback rates as of May 2026 — updated quarterly. We buy thousands of Aerons a year, refurb in-house, and resell direct to UK home-office buyers and start-ups, which is what underpins our published per-chair rates.
The short answer
A Grade A Herman Miller Aeron Classic (1994–2017) is worth £180 per chair on collection. A Grade A Aeron Remastered (2017+) is worth £250 per chair. Size B (medium) is the most common and most valuable; Size A and Size C are priced the same.
Grade B chairs (light wear, all functions working but cosmetic issues) drop roughly 20–30% — call it £120–£140 for a Classic, £180 for a Remastered. Grade C (significant wear or non-functional parts) can still hold £40–£80 if the parts are recoverable.
How we grade Aerons
Grade A — looks new. Pellicle mesh untorn, all adjustments work (tilt, recline, lumbar, arms), castors fitted and rolling, base un-scuffed. Most office Aerons under 5 years old are Grade A.
Grade B — light wear. Pellicle has minor sag (acceptable). Maybe a missing arm pad or a wobbly armrest. Tilt works but stiff. Sellable after light refurb.
Grade C — visible wear or broken components. Pellicle torn, lift seized, missing tilt mechanism. We strip these for parts (which keeps the secondary market alive) and pay accordingly.
Why Aerons hold their value
Three reasons. First: parts are fully interchangeable across decades, so refurbing is cheap and reliable. Second: there's a strong secondary market — UK home offices, start-ups, agencies, and refit projects all want premium ergonomic seating without the £1,500-a-chair retail price. Third: the chair itself is iconic. Buyers know what they're getting.
Aeron Remastered values are particularly stable because the chair is still in production. Buyers can compare your used £450 Remastered against the £1,400 new price and the maths is obvious.
What affects the price (in order of impact)
1. Generation — Classic vs Remastered is the biggest single factor (£180 vs £250 at our buyback).
2. Pellicle mesh condition — minor sag is fine, deep tears or burns drop you to Grade B or C.
3. Mechanism functionality — tilt limiter, forward tilt and recline lock all working.
4. Lumbar support — PostureFit or PostureFit SL must adjust smoothly.
5. Arms — fully adjustable arms preferred but fixed-arm Aerons exist and we still buy them.
6. Cosmetic — base scuffs, faded fabric on lumbar pad, missing logos. Minor effect, mostly Grade A vs B.
Are old Aerons (pre-2000) worth less?
Surprisingly, no. The Classic Aeron design didn't change meaningfully between 1994 and the 2017 Remastered. We pay the same £180 for a 2008 Aeron as a 2016 one, provided it's Grade A. The pellicle mesh ages (you might see slight discoloration on really old chairs) but the engineering is identical.
Pre-2017 chairs without the PostureFit / PostureFit SL upgrade are still standard Grade A — the upgrade was an option, not standard, on Classic Aerons.
Grade A vs Grade B — is it worth refurbing before selling?
Honestly: no. We do this for a living. Buying refurb consumables (new pellicle, new arm pads, new castors) and time-aligning everything costs more than the £40–£60 grade difference. Send the chairs as-is, we'll take them as-is, and you'll save the labour of trying to upgrade grades yourself.
How to identify your Aeron Size — A, B or C
Flip the chair over. There is a small stamp on the bottom of the seat pan with a single letter — A, B, or C. That is the size designation. Around 75% of UK office Aerons are Size B (medium) — it covers roughly 5'2" to 6'2" and is the size most often specified in corporate fit-outs. Size A (small, fits up to ~5'2") makes up about 15% and Size C (large, 6'2"+) the remaining 10%.
We pay the same headline rate for all three sizes — £180 for Classic, £250 for Remastered — even though Size B is materially easier to resell. The reason: we buy across all three because home-office buyers come in all heights, and a steady supply of A and C makes our reseller relationships easier to maintain. So do not assume your Size A or C is worth less; it is not.
Where size does affect price: a job lot of 50 Aerons that is heavily Size A or Size C might wait an extra 1–2 weeks for resale. We absorb that timing risk — your buyback rate stays the same.
Pricing table — by generation, condition and size
Aeron Classic (1994–2017), Size B, Grade A: £180 per chair. Same price for Size A and C.
Aeron Classic, Size B, Grade B: £120–£140 per chair (light wear, all functional, cosmetic issues only).
Aeron Classic, Size B, Grade C / parts: £40–£80 per chair (broken tilt, dead gas lift, torn pellicle — we still buy).
Aeron Remastered (2017+), Size B, Grade A: £250 per chair.

When is an Aeron worth refurbing vs parting out?
From our side, a Grade C Aeron is usually worth refurbing if the chassis, tilt mechanism, and Y-tower are all serviceable. Pellicle replacement (£35 in materials, 30 minutes labour for a skilled refurbisher), arm pads (£12), castors (£8) — these are all routine. What kills the maths is a bent or cracked Y-tower, a broken tilt housing, or a missing PostureFit SL bow on a Remastered. Those parts are either Herman-Miller-only-and-expensive, or only available second-hand.
From your side, the answer is different. We do this for a living and have refurb consumables in stock; you would have to buy them piece-by-piece at retail and learn the fitting process. Our buyback rate already reflects expected refurb cost. You will almost always get more by selling the chair as-is to us than by trying to upgrade the grade yourself.
Exception: if you have a single Aeron with one obvious fix (e.g. a torn pellicle that is replaceable for £35), and you are willing to spend an hour, you can lift it from Grade C to Grade B. We will pay the difference, but the £30–£40 uplift may not be worth your hour.
What we do with Aerons we cannot buy
If your Aeron is too damaged to make economic sense for refurb (cracked frame, snapped Y-tower, missing tilt cassette beyond economic repair), we still take it for parts — typically £20–£40 per chair, recycle the rest. Nothing fit for use sees a skip; nothing structurally beyond use enters a refurb cycle.
Recycled Aerons are stripped: pellicle goes to a textile-recycling partner, aluminium frames to scrap, plastic components to a polymer recycling stream. We issue a waste transfer note for any material entering the licensed waste route.
About 98% of Aerons we collect are refurbished and resold. The remaining 2% go to parts or recycling. The figure is published in our annual ESG report and audited against actual collection records.
