Story
For smaller living rooms
Thonet writes that the B 109 was developed when living rooms were much smaller than today: against the wall it takes up 45 cm, and when needed the panel is turned and unfolded.

Among the in-house designs
Thonet places the table among the tubular steel classics of the 1920s and 1930s, when the collection of renowned architects was complemented with numerous in-house designs.
