Proof of Concept is a dynamic exhibition platform exploring the intricate and captivating processes behind design. Showcasing work from a collective of multidisciplinary studios, it highlights self–initiated projects, products that never reached the market, and designs already in circulation. By shedding light on the extensive development process, the exhibition offers a rare glimpse into the evolution of a product—revealing the ideas, challenges, and creativity that shape its journey.

Proof of Concept — Connect is an exhibition that explores how materials, processes, construction and craftsmanship shape our relationship with everyday objects. Designers are invited to consider the role of tactile experiences, traditional techniques, and innovation in forging deeper connections between makers, users, and the spaces we inhabit. Through this exploration, the exhibition celebrates the tangible bonds that bring design to life.

Kilzi means many things to its founder: it is his family name, weird in his context and a symbol of other lands, Kilzi is the family context and a story of immigration and personal growth, it also means ancient history and heritage, movement, renewal, childhood. In Jorge S Kilzi's eyes, his creations are an expression of who he is and of where his many experiences have taken him. Kilzi's work is honest and seeks to create emotional value. Some items find their worth in practicality, technology, comfort or decorations: Kilzi doesn't refuse any of the previous but seeks value in human connection through objects. This year Kilzi will host one event and be part of two collaborative shows.

What began over 20 years ago as a spontaneous experiment in Tom Rossau’s Copenhagen workshop has evolved into a distinctive design philosophy. While shaping wooden slats into a cylindrical form, Tom discovered the expressive potential of light, material, and form, and a new chapter in Danish lighting design was born. Today, the collection has grown to include a wide range of materials and styles, yet the brand remains rooted in curiosity, craftsmanship, and sculptural design. Each lamp is still meticulously designed and handcrafted in Copenhagen, with a strong focus on quality and responsible production, bringing Danish design to interiors around the world.

Mikkel Nielsen is a Copenhagen–based design studio producing architectural lamps through 3D printing in bioplast. Each lamp is designed and produced in Copenhagen in small, limited series. The collection is defined by a clear formal logic: a single organic element repeated twelve times to form a balanced circular composition, creating a strong and recognisable identity. Production is intentionally kept small, allowing close control of material, surface, colour and light quality. The studio focuses on durability and long–term relevance rather than trends. At 3daysofdesign, the SSPL lamp is presented in 20 new colours.

Established in 2025, FIRPON's first endeavour is to bring the light back to the somewhat mythical Filosof Lamp, created by the notorious architect Lars-Erik Ejlers (1948–2024). Lars-Erik Ejlers carried the lamp with him wherever he went, from the bar at Hotel D’Angleterre to Holstein Bodega, turning Copenhagen’s nightlife into his personal showroom. To own a Filosof Lamp was to own a piece of a story, as it was often purchased directly from him during a late-night visit to a city bar, making it both rare and iconic. FRIPON now carries his vision forward, bringing the Filosof Lamp back to shine in modern spaces.
