A really quirky find.
 
A vintage folding usherette seat.
 
It has a steel folding mechanism and a hard wood seat. 
 
Apart from the obvious use, it would be a great plant display stand, a hall table or a fantastic bedside table for a small space. Folding away when not in use. So flipping quirky.
 
Measurements: 25cm seat diameter and 30cm projection from the wall. Height when flat against the wall 38cm
