Do Chairs Exist?

[Angrboda]

My question about trogs inspired a couple other questions. Let's suppose that sometime in the future, our civilization makes a "Dyson Chair" -- being a chair that is basically the size of a planet, made out of interlinked modules, and kept in orbit around the sun by way of the momentum that its enormous mass possesses. Is the Dyson Chair, which nobody could possibly sit on, a chair in the same sense as an ordinary piece of furniture. Let's suppose that said civilizations arrange the asteroids in the Oort cloud so that a group of asteroids together in the shape of a chair orbit the sun as one -- is that a chair in the same sense as your barcalounger? What if they used magnetic fields to force a portion of the plasma at the heart of the sun to assume chair shape and circulate only within the confines of that shape? I suppose that would be the very definition of "the hot seat."
