Geomantic speaking, the worst position is position 7, which is a dead position.
Position 6 is "Free from Death". You can understand for yourself. You see, you can't do it without the support behind you. In the window, there is no stable point to rely on.
The best seats are number 2, number 3 and number 4. Officially, these three positions are the themes in the room.
So, you'd better not move.
