Herman Miller Office Chairs Resale Value

Herman Miller office chairs: price by condition

Seller-declared grades, sterling with an approximate US dollar equivalent at £1 ≈ $1.33 (July 2026). What each grade means.

What holds its value across Herman Miller

• The Aeron, which has been in production since 1994, is repairable and has a deep second-hand market at every price point
• Size B Aerons, the middle and most common size, which suit the widest range of buyers and therefore sell fastest
• The Eames Lounge Chair and Ottoman in original leather, which is the company’s flagship design and is bought as furniture rather than as seating
• Chairs still inside the twelve-year warranty, which transfers with the chair and is a genuine selling point worth stating

What pulls Herman Miller resale value down

• Torn or sagging pellicle mesh, which is the Aeron’s defining feature and an expensive specialist repair rather than a home fix
• Failed gas lifts, where the seat sinks under load — cheap to replace but an immediate deduction because the buyer must do it
• Broken tilt mechanisms and seized forward-tilt levers, which are the moving parts that eventually go and are costly to source
• Cracked armrest pads and stems, which are the most-handled part of the chair and cannot be repaired convincingly

Identifying and dating yours

1. The size is marked on the back edge of the chair frame — A for small, B for medium, C for large — and it must go in the listing title, since buyers filter on it
2. A label under the seat gives the production date and the specification, which tells a buyer whether it is a classic or a remastered model
3. Photograph the mesh straight on with light behind it, since that is how sagging and small tears show up and it is the first thing buyers ask about

What lifts any office chair, whatever the label

A small number of well-engineered chairs dominate this market, and the gap between those and everything else is enormous.

• Recognised ergonomic models with parts still available
• Working gas lift that holds its height
• Intact mesh or foam with no collapse
• Original arms and castors

And what pulls one down

• A gas lift that sinks slowly under weight
• Torn mesh or foam that has flattened out
• Missing or mismatched castors
• Generic chairs, which sell for very little whatever their original price

Working out what yours is worth

1. Sit in it and time whether the seat height holds
2. Check the underside label for the maker and model
3. Test every lever and the recline lock

What to state in the listing

• Brand, model and size where applicable
• Whether the gas lift holds height reliably
• Which adjustments work: height, tilt, lock, armrests, lumbar
• Fabric or mesh condition, and whether the castors roll freely

Brand and model if it has one: “Herman Miller Aeron Size B Office Chair”. Recognised ergonomic brands sell for many times a generic chair and are searched by name and size. For unbranded chairs, lead with the features — mesh back, adjustable lumbar, headrest.

Preparing and photographing it

1. Sit in it and check the gas lift holds height for several minutes. A sinking chair needs the cylinder replaced and must be disclosed.
2. Test every adjustment: height, tilt, lock, armrests and lumbar support.
3. Clean the fabric or mesh, check the castors roll freely, and look at the seat foam for collapse.

1. The whole chair from a three-quarter angle
2. The seat surface and backrest, showing fabric or mesh condition
3. The base, gas lift and castors
4. The adjustment levers, plus any tear, stain or wear

When it sells best, and handing it over

Steady with strong lifts in September and January. Recognised ergonomic brands sell within days at good prices; generic chairs are abundant and cheap.

Usually collected. Most office chairs separate into seat, base and back, which makes them fit in a car — say so if yours does, because buyers assume they need a van.

What buyers ask

Which Aeron size should I say I have?

Check the marking on the back of the frame: A, B or C. Size B fits most people and sells quickest; listing the wrong size is the most common cause of a returned chair.

Is a used Aeron with a broken gas lift worth selling?

Yes. The part is inexpensive and widely available, so price the chair with the repair deducted and say clearly what needs doing rather than hoping it goes unnoticed.

How much is a Herman Miller office chair worth?

Roughly £48 to £288 depending on condition, against £30 to £180 for office chairs generally. The identification points above are what move a listing to the top of that range.

What the fees would take elsewhere

At the mid-range £168 for a Herman Miller office chair, against what the commission marketplaces would deduct:

Seller-side rates verified 26 Jul 2026, percentages only — the per-order and processing charges those platforms add are excluded, so the real gap is wider.
