To be clear: what did the Ottomans call this piece of furniture? If they didn't call it an ottoman, what was it referred to as? And why do we call [this] (https://i.imgur.com/T30JXsB.jpg) an ottoman in the first place?
I think your image links are broken.
Knowing almost nothing about the Ottomans, I have to wonder - did they even have ottomans?
