How do you get from Sapporo to Furano (or vice versa)?

On a recent snowboarding trip to Japan, this is a question that I didn’t have a good answer for before arriving. Looking at Google showed a few results, including a train ride that required a changeover with JPRail, but nothing that inspired me with confidence. Upon asking the staff (who were locals) at my accommodation, I was informed that the Chuo bus was probably my best option. Upon leaving my accommodation, this is what I decided to do.
