In short
A reputable 20th century furniture online store names the designer, the model, the maker or publisher, the date of manufacture and the condition of every piece, and it backs each statement with detailed photographs and a written description. The key distinction to check is between a period edition, made when the model was first produced, and a later reissue of the same design. Specialist galleries offer a narrower but better documented selection, while general marketplaces offer a wider choice in which provenance remains the buyer’s responsibility. Restoration is acceptable when it is disclosed and located, and delivery terms for large pieces should be agreed in writing. The sections below set out what to ask, what to look for and how to read a listing.
Choosing a 20th century furniture online store is first a question of information rather than of selection. On a single website, a chair from the 1920s can sit beside a recent reissue of the same design, and a photograph alone rarely shows the difference. A reputable seller treats this as the central point of every listing and answers it before it is asked.
This guide explains what a trustworthy online presentation contains, how specialist galleries differ from general marketplaces, how to distinguish a period edition from a reissue, and how to read condition, restoration and delivery terms. The examples come from French and international modernism, where the same models were often produced by several makers over several decades.

What makes an online store reputable for 20th century furniture?
A reputable store identifies each piece precisely and documents what it states. The designer, the model name, the maker or publisher, the approximate date of manufacture, the materials and the condition should all appear in the listing. The catalogue of such a store usually covers seats, tables, desks, bookcases, storage, lighting and ceramics, grouped by type and by designer so that you can compare like with like. A listing that gives only a style label, such as mid-century modern, leaves the essential questions unanswered.
It also helps to understand the vocabulary used. Architect’s furniture refers to pieces drawn by architects, such as the seats designed by Pierre Jeanneret for the administrative buildings of Chandigarh, usually in teak and cane. Mid-century modern, by contrast, is a period label for the post-war decades and says nothing about authorship. A tubular steel chair from the late 1920s and a Chandigarh armchair belong to entirely different histories, materials and constructions.
What a complete listing states
A complete listing separates the model from the object. The name of the model tells you which design is concerned, whereas the maker, the date of manufacture and the markings tell you which example you are looking at. Look for photographs of labels, stamps, joinery, undersides and any area of wear, together with a written description of the materials, such as solid wood, folded sheet steel, lacquer or bent plywood. If the listing mentions a designer as a collaboration, as with Charlotte Perriand and Pierre Jeanneret working alongside Le Corbusier, it should state precisely which part of the design each contributed. Vague attribution is a reason to ask for clarification.

Specialist gallery or general marketplace: what changes for the buyer?
A specialist gallery offers a narrower selection that is researched, described and documented by the seller, whereas a general marketplace offers a wider selection in which the buyer verifies the origin. Neither is better in absolute terms, and the right choice depends on what you are looking for. A collector seeking a period piece by a known designer will generally benefit from the depth of a specialist, while a buyer looking for a reissue for everyday use may find a broader marketplace sufficient.
Key points
Decide first whether you want a period piece or a reissue. Ask for the designer, model, maker, date, condition and restorations in writing. Request close-up photographs rather than a single general view. Treat a seller who answers vaguely or only orally as a warning sign. Authenticity rests on documentation, provenance and the opinion of a specialist, not on a single photograph or label.
Specialists also tend to work within a defined field, which allows them to place a piece in its context: the workshop that made it, the publisher that distributed it and the architectural programme for which it was designed. Archives play a part here. The Steph Simon archives, for example, document the distribution of designs by Charlotte Perriand and Jean Prouvé in Paris during the 1950s and 1960s, and such material helps to situate a piece. On a general marketplace, the same information may be missing, so the responsibility for checking the creator, the model, the publisher, the date, the condition and any restoration falls to you.
How do you tell a period edition from a reissue?
A period edition is made during the original production of a model, while a reissue reproduces the same design at a later date, often under licence. The two share a name and an appearance, but they differ in manufacture, markings and historical standing. The chaise longue LC4, designed in 1928 by Le Corbusier, Pierre Jeanneret and Charlotte Perriand, illustrates the point. Thonet produced it in its first years, and Cassina has produced it under licence since the mid-1960s. A chair from the earlier production and a chair from the later one therefore carry the same model name while representing different editions.
The date quoted next to a designer’s name is often the date of the design, not of the manufacture of the object. This is why the question to ask is always who made this example and when. The following points help to frame the answer.
- The maker or publisher named on the piece and in the listing.
- The labels, stamps or markings and where they are placed.
- Construction details, such as joinery, welds, fixings and finishes, compared with documented examples.
- Written documentation or provenance supporting the date.
| Point to check | Period edition | Reissue |
|---|---|---|
| Date of manufacture | During the original production of the model | After the original production, often under licence |
| Maker or publisher | The original workshop or publisher | A later manufacturer holding the rights |
| Evidence to request | Markings, construction details, provenance, documentation | Markings and confirmation of the edition from the seller |

What to check on condition, restoration and delivery before you buy
Condition, restoration and delivery should all be described in writing before you commit to a purchase. Patina is the change that time and use leave on a surface: wood that darkens, veneer that deepens in colour, metal that dulls. A period piece with no trace of use at all deserves a question, whereas a localised scratch, chip or repair should be visible in close-up photographs. A restoration is not a defect in itself, provided the seller states what was done and where. The real risk is an undeclared restoration, which alters the original state of the piece without your knowledge.
Delivery matters particularly for large furniture. Ask about the method of transport, the packing, the insurance and who bears responsibility for damage in transit. Withdrawal rights and warranties depend on the country of sale and on whether the seller is a professional or a private individual, so confirm these terms before paying instead of assuming them. For authenticity, ask the seller to confirm in writing the history of the piece, the original and replaced elements, and the edition and date of manufacture, and consider the opinion of an independent specialist for important pieces.
The most reliable online sellers answer in writing the questions that a photograph cannot settle: who made the piece, when, and in what condition.
Galerie Downtown presents pieces by designers such as Charlotte Perriand and Pierre Jeanneret, which can be browsed among the works of the gallery, including its seats. Whichever source you choose, the method stays the same: decide between a period piece and a reissue, ask for the maker, the date and the condition in writing, and read the answers carefully. A seller who documents these points clearly gives you what you need to judge the piece for yourself.

Frequently asked questions
How can you tell whether a vintage chair is a reissue?
You can tell by establishing who made the chair and when, since the model name alone does not indicate the edition. Ask the seller for the maker or publisher, the date of manufacture and photographs of labels, stamps and construction details.
The same design may have been produced by several makers at different periods, as with the LC4 chaise longue, first made by Thonet and later produced under licence by Cassina. Comparing the piece with documented examples and consulting a specialist helps to confirm the edition.
What should an online listing for period furniture include?
A good listing includes the designer, the model, the maker or publisher, the approximate date of manufacture, the materials and a description of the condition. It should also show close-up photographs of markings, joinery and any wear or repair.
It should state clearly which elements are original and which have been replaced or restored. A listing that omits these points leaves you to establish them before buying.
Is a restored piece of 20th century furniture a poor choice?
No, a restored piece is not necessarily a poor choice, because many pieces made decades ago have needed repair or refinishing. What matters is that the seller discloses the work, its extent and its location.
An undeclared restoration is the real concern, since it changes the original state of the piece without your knowledge. Ask for a written account of the work carried out and for close-up photographs of the areas concerned.
Can large pieces of 20th century furniture be shipped safely?
Yes, large pieces can be shipped safely when the packing, transport method and insurance are agreed in advance. Ask the seller how the piece will be protected and who is responsible if it is damaged in transit.
For international shipments, also ask about the delivery conditions at your address and about any customs formalities. Obtain these answers in writing before you pay.
How is the authenticity of a piece bought online established?
Authenticity is established through documentation, provenance and the opinion of a specialist, never through a single photograph or label. Ask the seller to confirm in writing the history of the piece, the edition and the date of manufacture.
Compare the markings and construction with documented examples, and consider an independent expert’s opinion for significant pieces. Archives and publications on a designer’s work are useful references for this comparison.
