Recently I acquired six pressed cane and chrome bar stools.  I'm not sure if they are original Breuer Cesca chairs.   I also have six black pressed cane and chrome chairs.  The greatest difference between the two is the seat.  The chairs seat slightly curves over the tube, the bar stool seat does not.  Also, the bar stool tube is jointed were the chairs chrome tube frame is one continuous piece.   The chair is actually heavier  than the bar stools.  I remember this style chair made a comeback in the 70s and early 80s. Anyone familiar with the show Freaks & Geeks will remember the Wier family at the kitchen table sitting in these chairs( Episode 2: Beers and Wiers).
