Material Matters is a platform dedicated to exploring the role of material intelligence in architecture and design. With more than 150 podcasts published and four acclaimed editions of its annual fair staged in London, the brand made its international debut in Copenhagen in 2025 as part of 3daysofdesign. The debut fair exceeded expectations and confirmed the appetite for a deeper, more material–led conversation during Copenhagen's design festival. Building on this success, Material Matters returns to 3daysofdesign, reflecting design and architecture's fascination with what materials can do—and what they should no longer be asked to do.

Based in Uji, Kyoto, Asahiyaki is among the oldest ceramic kilns in Japan, having crafted tea wares in the same family for 425 years.
This rich history provides a unique perspective of time. Clay used today was extracted two generations ago, just as new clay is prepared for future generations. Tea vessels are not considered complete when they emerge from the kiln; they reach fulfilment gradually, through years of daily use. Besides making artistic pieces for the tea ceremony and sencha wares for daily use, Asahiyaki collaborates with global brands and restaurants on bespoke tableware collections. Every piece is thrown by hand on the pottery wheel by skilled artisans.

Kvik’s originality comes from redefining how people live in their kitchens. Since 1983, Kvik has focused on human connection, not just cabinetry—coining and trademarking the term Samtalekøkken® long before open–plan living was a trend. That idea—bringing conversations, family, and daily rituals into the heart of the home—has since become the global standard. Kvik designs with purpose: every line, material, and surface has intent, evolving the concept it pioneered while keeping it human–centred and true to Danish design values. Kvik keeps it fresh by collaborating with leading Danish designers like Rikke Frost, Hans Thyge, Says Who, and supporting rising talents such as Annika Hoffmann and Bly Studio.
