This vintage Russian stool will have been used in a factory or similar industry.
 
It is heavy and robust and the height can be adjusted by turning the seat. It has had a slight refurb by replacing a broken seat. This was done sympathetically using a vintage stool seat.
 
It is obviously a great stool or alternatively a side table beside the bed or armchair or as a plant stand.
 
Measurements: height adjustable, seat diameter 32cm
