Hallingdal 65 was developed in 1965 by Danish furniture designer Nanna Ditzel, it has a unique wool-and-viscose composition and a rich, tweedy texture that’s been rolled out everywhere, from airports and hospitals to museums and private homes. The manufacturer, Denmark-based Kvadrat, has reportedly sold more than 13 million feet of the fabric. Today, you’ll find Hallingdal 65 between the hallowed walls of MoMA and in the showrooms of Fritz Hansen and Moroso.

But nearly 50 years have passed since Kvadrat first released the textile, its first ever. Amid an ever-expanding roster of sleek, technologically sophisticated upholstery, Hallingdal lacks the novelty of its competitors. So to mark the fabric’s relaunch this year in almost two dozen freshly issued shades, Kvadrat tapped seven curators--including Tord Boontje and Ilse Crawford--and dozens of young designers to “reinterpret the classic textil in a modern context.” The updates were featured in an exhibit during the Salone del Mobile, a furniture fair in Milan.

The point was to show other designers--the fair’s primary audience--how much new life they can breathe into a classic design.
