The designers Ana Relvão and Gerhardt Kellermann often compare their work with solving a Sudoku puzzle: what is present must continuously be questioned and each time aligned anew; yet the function and the practical value of an object remain fundamental to their designs.

The result of this process are self-evident products, which users can easily understand, products, whose reduced forms radiate nonchalance and discreet elegance. Relvãokellermann live and work in Munich. Besides being sought by international companies, they also work for cultural institutions and teach as visiting professors for industrial design at the Academy of Fine Arts in Stuttgart.
