An ottoman without a chair is a stool and the Ashanti Empire wasn't one of the defeated powers in World War I. 
An ottoman is a form of couch which usually has a head but no back, though sometimes it has neither. It may have square or semicircular ends, and as a rule it is what upholsterers call "overstuffed"—that is to say no wood is visible.[1] It may be used as a stool, footstool,[2][3] coffee table,[4] or as an alternative to a sofa.[5]
