The Eternity Fully Upholstered Armchair, Set of 2 from Mater, is designed by Space Copenhagen. Each armchair is crafted with a commitment to sustainability, using innovative materials sourced from coffee shell waste from BKI’s coffee roasting process or wood waste mixed with post-consumer e-waste. This approach results in subtle detail variation. The upholstery of the armchairs is made from high-quality wool. The fill material consists of Kvadrat Re-wool, a blend of 45% recycled wool, 45% new wool Worsted, and 10% nylon.
