Fine condition and a pleasing configuration along with lovely, tapestry-style fabric. Only AI could further improve these accolades; I'll spare you that.
It appears that the original upholstery has been replaced at least once, according to the holes in the wood underneath. I heartily approve of the most recent choice.
Judging from the style and the age of the fabric underneath, along with the evidence of prior coverings, I'd say the stool/ottoman is in the neighborhood of a hundred years old.
Both the wood and the fabric are in fine condition; no significant issues.
Measurements: Thirteen inches high and 16 x 20 inches across the top.
