Product designer Annabella Hevesi prototyped this unusual Crosses chair.

Rather than traditionally tufting the upholstery, she's experimenting with the following technique:

"The motivation for designing this collection was to try a new mechanical joint solution that allows a new approach to shaping the comfort foam. Originally, in the upholstery furniture industry the comfort foam is shaped by cutting or casting it: the first results in a lot of waste and has limits of shape, and the second is extremely expensive and thus only suitable for high-volume production."

"The new joint solution's point is that we have some external tools (metal elements are produced by additive technology) that distort and press the foam to reach its final shape. This method reduces waste and makes a mechanical connection among the components instead of gluing."

That's just a brief excerpt of Hevesi's notes; she's written more of a manifesto on the subject that you can read here.

Hevesi and partner Gábor Bella make up the Budapest-based design duo known as Line and Round.
