How many seasons of upright are there?

I'm curious, could you please clarify the context of the question "How many seasons of upright are there?"? It seems a bit unconventional as "upright" is not typically associated with seasons in the traditional sense, like television shows or sports leagues. Perhaps you're referring to a specific product, brand, or even a metaphorical usage of the term. Could you elaborate or provide more context so I can better understand the inquiry and formulate an appropriate response?
