Vitra ID Trim
The Vitra ID Trim is one member of Antonio Citterio's modular ID Chair Concept — the version with a slim "sandwich-construction" back and an integrated lumbar, giving upholstered comfort in a profile almost as thin as mesh. This guide explains the ID family's back types, the ID Trim's options, and how to buy one.

Check these before you buy
"ID Chair" is a family, not one chair. The first decision is the back type; then the mechanism and arms. Confirm these before ordering.
Dimensions and fit
Manufacturer figures come from the maker's official product page; we check them against the Amazon listing before treating them as confirmed. Values we can't confirm for the linked listing are marked as such — take those from the listing you buy from.

Sources: vitra.com ID Trim / ID Trim L / ID Chair Concept pages and published reviews (checked 2026-09-10). Vitra publishes seat height and seat depth in the ID Chair factbook and a 5-year US warranty; it does not publish a weight capacity — request it from your seller before treating those as confirmed.
Adjustable vs fixed
Design, ergonomics & build — in depth
One family, four backs
The Vitra ID Chair Concept is Antonio Citterio's modular office system: a shared mechanism and frame offered with four different backs, so the "ID Chair" you buy is really defined by which back you choose. ID Air uses a perforated plastic back; ID Mesh a padded mesh; ID Soft a fully upholstered classic back; and the ID Trim — the version featured here — a slim "sandwich-construction" back with an integrated lumbar that delivers upholstered comfort in a profile almost as thin as mesh.
Seeing the difference
The back type changes both the look and the support, so it's worth seeing the alternatives before you commit. The ID Soft gives the softest, most traditional executive feel; the ID Mesh trades some of that for airflow and a lighter visual.
Mechanism, arms and the buying reality
Whichever back you choose, the ID Trim can be specified with Vitra's patented FlowMotion synchronised recline — adjustable while you're seated — or the self-adjusting AutoMotion, which sets its resistance to your weight automatically. Arms go up to 3D with 360°-rotatable pads, and the chair is engineered to simulate a roughly 15-year service life. The catch is information: Vitra doesn't publish the seat-height range, weight capacity or warranty on these pages, and in the US it's a Vitra-shop or authorized-dealer purchase rather than an Amazon click — so request the full spec sheet from your seller before buying.

Comparisons with key rivals
Rival figures are from published sources and are not verified by Chairpedia. Prices move constantly, so we link out instead of printing a number.
| Model | Lumbar | Armrests | Standout |
|---|---|---|---|
| Vitra ID Trim | Integrated (in the slim back) | Up to 3D + 360° pads | Citterio design; slim sandwich-construction back |
| Vitra ID Mesh | Integrated | Up to 3D | Same family, padded mesh back |
| Herman Miller Aeron | PostureFit SL | Up to fully adjustable | All-mesh, three sizes, easy US buying |
| Steelcase Gesture | LiveBack | 360-degree | Most flexible arms, US-common |
The bottom line
The ID Trim is the design-object entry to Antonio Citterio's modular ID Chair Concept. Where the family also offers a perforated plastic (ID Air), padded mesh (ID Mesh) and fully upholstered (ID Soft) back, the ID Trim's slim "sandwich-construction" back with an integrated lumbar gives upholstered comfort in a profile nearly as thin as mesh — paired with Vitra's patented FlowMotion synchro (or a self-adjusting AutoMotion) and up-to-3D arms with rotating pads, in a chair engineered to a ~15-year service life.
The friction is information and access. Vitra doesn't publish a weight capacity, and in the US it's a Vitra-shop or dealer purchase rather than a click-to-buy Amazon product — so request the full spec sheet and confirm the seller before committing. If you want a refined, design-led contract chair and don't mind that process, the ID Trim is distinctive in a way the American flagships aren't; if you want published numbers and easy returns, an Aeron is simpler.
A Citterio design with a slim integrated-lumbar back — decide the back type, then get the full spec sheet from your seller.
Where to buy
Not verified by Chairpedia: price, seller, stock, options and — because Vitra doesn't publish a weight capacity — confirm it with the seller. In the US this is a Vitra-shop or dealer purchase. The Amazon search link is an affiliate link and will mostly surface unrelated items; the Vitra link is a direct, non-affiliate link. Confirm the exact model and specs with your seller.
Frequently asked questions
What's the difference between ID Trim, Mesh, Soft and Air?+
They're back types in the same ID Chair Concept family: ID Air (perforated plastic), ID Mesh (padded mesh), ID Soft (fully upholstered), and ID Trim (a slim sandwich-construction back with an integrated lumbar). This guide covers the ID Trim.
FlowMotion or AutoMotion?+

Not as a genuine product page. In the US the ID Trim is bought through Vitra's online shop or authorized dealers.

Vitra lists a seat height of 400–520 mm in the ID Chair factbook. It does not publish a weight capacity; ask your seller before buying.
