Hi,
These are all great suggestions. The strong, high-backed chair will be of greatest significance in symbolizing support while you are seated at your desk. The fact that there is part of a window behind you can be remedied by the picturd of the mountain. Having a window behind you as you sleep tends to affect your clarity and rest more than a window behind your desk would.
You can also slow the energy down with a beautiful rug, plants help as do any beautiful wall hangings. The energy will move as your eye does. When you stand in the room where do you notice your attention is drawn? This is how the energy moves as well.
All the best!
