Considered a design classic, the ST04 Backenzahn has become an identifying icon for e15 and part of several permanent exhibitions in Museums. With its four identical legs made of solid wood the stool gives a strong impression. The legs taper downward with two deliberate incisions. The gaps between the legs suggest that all four parts are still clearly recognizable, and the slightly concave seat provides sitting comfort. This piece can also be supplied with a flat top to be used as a side table.
