Rummaging in the treasure trove of prints I bought recently I found this from Ackermann’s Repository of Arts (July 1814). It is captioned “Design for an Ottomane [sic] Couch” although I doubt whether any citizen of the Ottoman Empire would recognise it!
It is obviously designed for a very large house and it looks decidedly uncomfortable – but fashion overrides comfort, presumably. I’m at a loss to identify ‘Ottoman’ influences – the two half-figures of naked women look decidedly Egyptian in origin.
If it was mine I think I’d be worried about male guests dangling a hand over the end and groping the ornaments…
