...that folds from a recumbent into an easy chair suitable for my living room.
That way I can get a recumbent without making extra space in my home to put it (just replace one of my chairs).
Being able to pass for a wheelchair would be a plus (though I doubt there's any kind of legal preference for wheelchairs when they aren't accompanied by disabled persons, I doubt most people/guards would question).
Too big. The rear wheels make that couch the size of a bed.
I'm thinking practical here. Most folders take up the same amount of space as a typical chair. So why not simply have a folder transform into a typical chair? After all, regular chairs are so useful that a folder that transforms into one can never been in the way.
