Set of 4 Baumann sleigh chairs

4 vintage baumann sled dining room chairs from the 70s. Also called sled chairs. In good general condition for chairs purchased in 1975, some signs of use (see photos). The foam padding was redone about ten years ago, still very comfortable, and the fabric is new in keeping with the spirit of the period. The wood of the frame is dark wenge stained beech (almost black) the veneer of the backrest appears to be stained ash.
