There is no historical record on how and where the Hanging Chair originated. It is possible, though, that European immigrants developed it as they wanted to relax lying and sitting. When doing so, they might have been inspired by the idea of a suspended piece of furniture, which they already knew in form of the hammock.
Space-saving alternative to hammocks
You only need one suspension point for a Hanging Chair, which can be placed in the ceiling or in a beam. A Hanging Chair does not need more space than a conventional armchair, thus it is very easy to integrate it into the already existing ambience. If it is not needed it can be taken down in a matter of seconds.
