Curved wooden piano stool

Curved beech wood screw set made in the late 19th, early 20th century by kohn (thonet competitor) in vienna, austria. Sitting in good condition, just like the whole stool, except for a little game at the screw. Set at the lowest, the seat is perfectly stable but by raising the seat height, there is a game creating a slight imbalance; all this being related to the great age of furniture.
