This Space-Frame series of furniture, by Berlin-based architect Gustav Düsing, was designed over a decade ago as an experiment. It's a pity it wasn't pursued further. Made of Baltic Birch plywood, the pieces could conceivably be cut on a less-than-full-size CNC mill and would obviously ship flatpack.

"The Space-Frame series…are based on space-consuming structural elements (space-frame). The aim was to test architectural principles of scale, structure and production on a real object. Digital and manual techniques have been researched and developed in a series of prototypes. The resulting furniture was produced in small series with a network of workshops."

I found the Chair23D the most visually arresting of the bunch:

"The Chair23D is based on the typology of a lobby chair, similar to the Barcelona Chair by Mies van der Rohe. The complex three-dimensional structure can be assembled without adhesive or screws to form a stable, self-contained system. The construction is an extension of the human skeleton, with a spine connected to a series of ribs and a kind of pelvis from which the rear legs are held."

The form has fantastic splay and gesture. Moreover, while I've seen plenty of CNC-cut, slot-together furniture, Düsing's intelligent design conceals all of the unsightly dogbones and half-rounds while still celebrating the joint, turning it into its own visual element. I think if pursued, this could've found its place.
