An Etymological Dictionary of the German Language/Annotated/Stuhl
Stuhl, masculine, ‘chair, seat,’ from the equivalent Middle High German and Old High German stuol, masculine; corresponding to Old Saxon stôl, Dutch stoel, Anglo-Saxon stôl, English stool, Old Icelandic stóll. A common Teutonic noun, derived from the Aryan root stā̆, ‘to stand’ (see stehen), or from the Aryan root stal, ‘to put, place’ (see stellen), hence Stuhl, literally ‘stand, frame’?. It corresponds in the non-Teutonic languages to Lithuanian pastólas, ‘stand, frame,’ Old Slovenian stolŭ, ‘seat, throne,’ Greek στήλη, ‘pillar.’
