The original BACKENZAHN™ designed in 1996 by e15 founder and architect Philipp Mainzer is a modern design classic as well as an identifiable icon for e15. Crafted in Germany, the stool (with shaped seat) or the side table (with flat top) is offered in oiled European oak or walnut. For its signature form and detail the centre of the tree is used. During the seasoning of the solid wood, the legs form their characteristic cracks, which make every stool unique.
