The ivory pedestal is (in my mind) the accompaniment to Sottsass' TARTAR Cubist-like sideboard --- a visual attempt to show each elevation/plain as though it were 3-D rather than a flattened 2-D.
You can spin it a third-round every week, and get a completely different table because each of the three sides is different. This table was Sottsass' contribution to the 5th MEMPHIS opening in Milano Italy.
