How can I tell what decade a modern piece was made?

Start with any labels, stamps, or model numbers, since some makers changed their labels over time, which helps date production. Construction and materials also give clues. Certain types of hardware, finishes, fabrics, and manufacturing methods were more common in particular decades.

Style can help, but it is not always reliable, because designs from one era are often reproduced or reissued later. Wear and patina should be consistent with the age claimed. Compare your piece with documented examples in reference books, auction archives, and dealer listings.

If dating is important for value, consult a dealer or appraiser who specializes in modern furniture. They are familiar with the small details that distinguish early production from later versions, and they can often give you a more confident estimate of age.
