The newest batch of rebar based chairs is well under way- these will be much less Geometric, more to the "organic" end of the spectrum.
Here are some photos of the seats being constructed.
The main differences are: mesh rather than sheet metal seat top, the mesh is bent over an inner ring and then an outer hoop is set a little lower in an effort to round the top corner of the seat for comfort.
The legs are upset and made into a beautiful spontaneous curve for the organic look.
