Morphology

fall + off + one + chair

The phrase is clearly built from literal parts (fall + off + one's + chair), so a learner will readily picture someone physically falling from a chair; however, its common use as a hyperbolic reaction meaning 'be extremely surprised or amused' is a metaphorical extension of that image and not fully predictable from the parts alone. Because the idiomatic, exaggerated meaning requires pragmatic or cultural knowledge beyond the literal constituents, it is only partially transparent to a B1 learner.

Etymology

The idiom fall off one's chair comes from a simple picture of someone so shocked or amused that they actually fall off their chair. That's why it now means 'to be extremely surprised or amused'.
