Stool Series is a minimalist collection created in collaboration by Jasper Morrison and Wataru Kumano for More Trees. The stool celebrates the 10th anniversary of the Japanese forest conservation organization More Trees. The company seeks to promote products that utilize local Japanese wood, using material that would otherwise go to waste. The stools are constructed of Japanese Hinoki and come in three variations: single, double, and long. The wood is sourced directly from Higashi-Shirakawa in Gifu, Japan.
