It’s a little counter-intuitive. Why do you want a skull on the back of the chair. Well, you’ve got your slightly raised dais. It’s on one edge of the open chamber where you’d like to confront your enemy. The skull side faces the center of the chamber. The chair-side faces the wall of view screens, or crazy-wall of strings connecting newspaper articles about your exploits, or the shrine showcasing your mother’s dessicated head. Your enemy or enemies gather behind you in the room, seeing the great black skull, until you choose the precise moment to rise from the chair and reveal the means with which you will dispose of them.
I’d skip the swivel and just have the seat lower, so you can step forward and use the skull as a podium. If perchance things go sour, activate rockets and the whole skull/chair/podium doubles as an escape pod.
