How do I identify a Thonet chair?

To identify a Thonet chair, look under the seat. Most Thonet chairs will feature a maker's marking. Often, you'll find the Thonet name carved into the wooden seat frame or printed on a paper label mounted on the seat's underside. Because Thonet changed its markings over the years, you can get a rough idea of the age of your chair by comparing the ones on your piece to images on trusted online reference guides. If you need help with the identification process, a certified appraiser or knowledgeable antique dealer can be of assistance. Find a range of Thonet chairs on 1stDibs.
