Interior & design: what we accept

We select authentic, well-designed furniture and decorative objects from recognised designers and brands. The minimum expected value is €75 — and €1,000 for exclusive designer pieces. You may combine related objects into one submission to reach the threshold. Every lot is reviewed by an Auctium interiors expert before it can go live.

What we accept

• Contemporary designer furniture and decorative objects designed after 2000.
• Vintage and mid-century design by recognised designers — Charles & Ray Eames, Poul Henningsen, Gio Ponti, Pierre Paulin, Hans J. Wegner, Arne Jacobsen, Charlotte Perriand, Ettore Sottsass — and brands such as Artifort, Thonet, Fritz Hansen and Cassina.
• Hand-crafted objects and pieces offered directly by their designer or brand.
• Pre-owned or new pieces that are authentic, functional and in good condition, photographed well and described accurately.

Iconic pieces with documented provenance — original purchase receipts, manufacturer labels, catalogue references — are approved fastest and earn the strongest bidding.

What we do not accept

• Unauthorised replicas or imitations of designer works.
• Objects that are broken beyond restoration — cracked glass, warped plastic — or non-functional technical devices.
• Large-scale mass-produced objects without design provenance.
• Grouped submissions without cohesion between the objects.

Required details

The submission form guides you through the essentials — complete every field, and give dimensions for each object separately when submitting a set:

• Designer — the designer, creator or studio, where known.
• Brand — the manufacturer, e.g. Cassina or Fritz Hansen.
• Style — e.g. Mid-Century Modern, Bauhaus, Postmodern, Scandinavian.
• Materials — woods, metals, upholstery and finishes.
• Dimensions — W × H × D in cm, including seat height for seating.
• Year and condition — production period, signs of wear, and any restoration.
• Description — the story and production process, country of origin, provenance, and anything a buyer must know.

Photos

Upload 7–8 high-quality images, shot indoors at a relatively low angle — not from above — in a calm, neutral space with natural light. Your set must show:

• Front, back, top, bottom and both sides.
• Close-ups of labels, maker's marks and signatures.
• Every flaw or sign of wear, photographed close-up.
• For sets: one photo of everything together plus individual shots of each object.

Proof of authenticity

For exclusive pieces — furniture valued €1,500 or more, accessories €1,000 or more — we require supporting evidence:

• Proof of provenance: receipts, catalogues or other documentation.
• Evidence of designer attribution: labels, serial numbers or original manufacturer confirmation.
• Supporting materials such as books, posters or exhibition references.

Signatures and limited-edition markings count only when verified by the original producer or a reputable third party; unverified markings are disregarded or lead to rejection.

Check before you submit

Condition disputes are the most common reason interior sales are unwound. Verify three things before listing:

• Structural integrity — handle the piece, don't just look at it: joints, filled holes, sagging foam. Any movement in the joints must be stated and photographed.
• Function — test lamps for flicker and chairs under weight. Original, untested wiring must be disclosed explicitly.
• Completeness — confirm brackets, counterweights and mounting hardware are present, photograph all loose parts, and state clearly if something is not included.

A description that sells

Name the designer, manufacturer, model, period and materials first; then condition, restoration and provenance. A paragraph of history turns a chair into an object worth bidding on.
