An idea for the base

This is the prototype--side view.  We cut this out of wide flat steel bar and will weld them together.  Each stool will have 2 legs connected with spanner bars front and back.  We will grind the welds flat and patina the whole thing gun metal black.  What do you think about that?

It was fun re-learning geometry (the rear angle is 85 degrees--subtle, we think).
