What is a used Herman Miller Aeron worth in the UK?

UK price guide

What is a used office chair worth?

The same chair asks £165 from a private seller and £475 to £800 from a refurbisher, against a list price of £1,659 for the Remastered. Task seating is the one category where the dealer premium is usually justified, because a refurbished chair has had the parts that actually fail replaced and carries a warranty on them.

Why the range is that wide

This is the one category in these guides where the dealer premium is usually worth paying, and the reason is specific. An Aeron fails in known places — the pellicle mesh, the gas lift, the tilt mechanism and the armrest pads — and a refurbisher replaces exactly those and warrants them for twelve months. A £165 private chair may be perfect or may need a £120 mesh and a gas lift, which is most of the gap. Size is the other trap: Size B is the common one, and A and C routinely cost more because far fewer were made. Note also that the £1,659 figure dealers display is the list price of a new Remastered, not a resale value, and it is there to make the refurbished price look like a saving.

What moves the number

Classic or Remastered

Two different chairs sharing a name. The Remastered is newer and commands roughly double the Classic at the same size and condition.

Size A, B or C

B is the common size. A and C were made in far smaller numbers and consistently cost more, which makes a lot of mixed sizes harder to price than it looks.

Pellicle, gas lift and tilt

The parts that actually fail. Replaced-and-warranted is worth a few hundred pounds over as-is, and a sagging mesh is the one fault a buyer can see in a photograph.

Specification

Lumbar support, fully adjustable arms and posture fit are real money. 'Fully loaded' is not marketing on these chairs, it is a different product.

Quantity

A matched lot of nine at £450 each is a better outcome for a seller than nine separate £165 sales, and less work. Volume raises the per-chair price here rather than lowering it.

Got some to sell?

Listing on LotLoop costs nothing and always will — sellers pay 0% commission, permanently, and it is not a promotion. You receive the full amount you list or agree, because the LotLoop commission sits on the buyer’s price rather than being deducted from yours.

Send what you already have — a stock sheet, a spreadsheet, a few phone photos — and LotLoop writes the listing from it. Nothing is published until you have read it back and approved it.

The limits of these figures

These are asking prices, not sold prices. Nothing here reflects what a chair actually changed hands for.
Figures marked seller-published come from dealers who refurbish and resell these chairs; some quote 'from' prices for the cheapest specification they stock.
Dealer prices are usually quoted excluding VAT and private listings including it, a 20% difference before anything else is compared.
The research covered Aeron and Mirra 2 specifically. Other task seating was not found at comparable detail, so do not read these ranges across to unbranded chairs.
List prices shown by dealers, such as £1,659 for a new Remastered, are retail prices and not resale values.
