Koppanen's innovative material research includes the Fomes amadou seating design, which utilises Amadou's unique properties to upholster stylish furniture, blending traditional techniques with modern aesthetics. The Fomes range, featuring chairs and benches, emphasises amadou's organic beauty and utility, pushing the use of fungal materials in everyday items, and revitalising the ancient art of amadou-making for today's design world.
In a similar vein, her project Sensorial Bowls builds on the tactile qualities of amadou and birch burls to promote a hands-on exploration of these materials. By designing these bowls, Koppanen encourages a closer interaction with the natural textures of fungi and plants, reflecting on their essential roles within ecosystems. Here, the symbiotic relationship between the growth-promoting burl and the decay-facilitating polypore mushroom serves as a poignant reminder of nature’s intricate balance—where one force drives growth and the other facilitates decay, yet both are necessary for ecological harmony. This project continues Koppanen’s theme of blending tradition with innovative design, fostering a deeper appreciation and understanding of natural materials in our daily lives.
