How do I date Knoll furniture?

How to date Knoll furniture depends on the piece. Some pieces feature stickers that bear the brand's name and logo, and the graphics changed over the years. By comparing the style of the logo to samples online, you can estimate the age of the piece. In some cases, the manufacturing year may appear on the sticker. To date a Knoll chair, look for the tag sewn on the back of the seat cushion. Often, the manufacturer prints the date there. You'll find a collection of expertly vetted Knoll furniture on 1stDibs.
