In addition to being one of the most sustainable woods, cork is a tough, lightweight industrial design material. These stools, designed by Jasper Morrison for Vitra, use cork that's limited to 9 year harvest cycles, meaning the same tree can harvested for generations. They also fit perfectly within Jasper Morrison's stated design mission: “to produce everyday objects for everyone’s use, make things lighter not heavier, softer not harder, inclusive rather than exclusive, generate energy, light and space.â€
