the.com/seat

means A surface or place made for sitting — and by extension, a position, role, or location someone occupies, like a seat in parliament or a seat of government.

from From Old Norse 'sæti,' meaning a place to sit, brought into English through Norse settlement and contact. It's related to the Old English 'sittan' (to sit) and sits in the same old Germanic family as 'sit' itself — the word simply means 'the thing you sit on,' and it widened over centuries to mean the position or authority that comes with the chair, not just the chair.
