Backenzahn Stool

Made by e15

Designed by Philipp Mainzer

The Backenzahn is one of those rare objects that arrives fully formed, requiring nothing added and nothing removed. Philipp Mainzer conceived it as an exercise in structural candor: four identical legs in solid oak or walnut, joined with a precision that keeps each element visually distinct through a deliberate reveal at their intersections.

The slightly concave seat is not an afterthought. It is a quiet acknowledgment that a stool must be sat upon, and that comfort and geometry are not opposites. The form reads differently from every angle, shifting from monolithic to airy depending on your position.

What makes each Backenzahn genuinely singular is what happens during the seasoning of the wood. Solid oak and walnut develop characteristic cracks as they cure, a natural process that Mainzer embraces rather than corrects. No two stools carry the same marks. The wood's history becomes the object's identity.

Frequently Asked Questions

What wood options are available for the Backenzahn Stool?

The Backenzahn Stool is offered in solid oak and solid walnut. Both species are seasoned after production, developing natural cracks that give each individual stool its own character.

Are the cracks in the wood a defect or intentional?

The cracks are an intentional and celebrated aspect of the design. Solid wood develops fissures as it loses moisture during seasoning, and Philipp Mainzer treats this as a mark of authenticity rather than an imperfection.

Can the Backenzahn be used as a side table as well as a stool?

Yes. Its proportions and flat, concave seat surface make it a natural candidate for use as a side table or occasional surface, and it is frequently specified in that role by interior designers.

Who is Philipp Mainzer and what is his relationship to E15?

Philipp Mainzer is a Frankfurt-based architect and designer who co-founded E15 in 1995. The Backenzahn is one of his earliest and most enduring designs for the brand, now considered an icon of the E15 collection.

How should solid oak or walnut furniture be maintained over time?

Solid oak and walnut develop a patina with use and light exposure. Periodic treatment with a natural oil or wax preserves the wood's surface and deepens its color, while the seasoning cracks require no intervention and are best left as they are.
