According to NobleChairs itself, the Epic is suitable for heights between 175 - 205.
You can already tell that this chair is more for taller and well-built people.
It's really difficult to give a recommendation here... Actually, I would advise you to "test sit" this model somewhere, but it turns out that these chairs are hardly ever on display... :-S
With the stool, you could of course overcome the problem with the footrest, but it is still questionable whether the rest of the ergonomics are to your liking. (Back, armrests, etc...)
