No. Although the pope’s infallible pronouncements are called ex cathedra (Latin, “from the chair") statements, he does not have to be sitting in the physical chair (which is rather high off the ground in any case).
In fact, he doesn’t have to be seated at all.
He simply has to use the fullness of his authority as the successor of Peter to definitively teaching a particular matter pertaining to faith or morals.
This use of the full extent of his teaching authority is referred to figuratively, as him speaking“from the chair” of St. Peter.
It’s a figurative expression, not a reference to the physical object.
