Iron Throne

`The Iron Throne is the seat of the Lord of the Seven Kingdoms and is often used as a metonymic device to refer to the king's authority. The king often holds audiences and dispenses justice from atop it in the Red Keep's throne room. The chair itself is cold and hard, with many jagged edges.[2]

Only the Hand of the King may sit on the throne in the king's absence. Such privilege does not extend to regents

Appearance
The Iron Throne is an asymmetric monstrosity of spikes and jagged edges and twisted metal. It is uncomfortable, and the back is fanged with steel which makes leaning back impossible. Aegon I had it made this way deliberately, saying that a king should never sit easy.

Since the construction of the Red Keep in King's Landing, the Iron Throne has been located on a high platform in the throne room within the castle. Usually, the members of the Kingsguard stand guard below. When the king is presiding, only he, his family, and his council may sit; all others must stand or kneel. During the rule of the Targaryens, the throne room was decorated with the skulls of their dragons
