Comparative degrees show, obviously, degrees of comparison. The more common expressions involve "more" and "most." If you think about it, this mechanism is actually used to *describe* states of being...well, nouns and pronouns, and verbs; therefore these degrees exist only within adjectives and adverbs.
Unfortunately, the word "up" is not primarily an adjective or an adverb, although it can be used as such. It is a preposition, used to show how its object is related to the general concept of the sentence they happen to be in. Used as an adverb, it's usually found at the end of a sentence, as in: "English moves you up." This is, let's face it, rather irregular usage, although by no means grammatically wrong and unacceptable.
So is there a comparative form for the word "up"? "More up." But it's clumsy, okay, so I suggest that you rephrase your sentence in order to move around this problem.
Cheers.

Teapot is a noun and, as such, does not have a comparative degree.
Oh, dude, you're hitting me with some grammar stuff! So, the comparative degree of "biggest" is "bigger." Like, you know, if something is big, and then you compare it to something else, you'd say it's "bigger." It's like saying, "This burrito is big, but that burrito is even bigger."
The comparative degree is wider.
