@ezekiel43: It's a cozy setup now. I have the same situation with my centre channel. I could put it on top of my entertainment unit, but then I would have to mount my TV to the wall to raise it higher. Right now I use the TV stand and the centre of the screen is lined up with my eyes. Due to sitting fairly close to my TV, I can not have both the centre of the screen at eye level and the centre channel at ear level. So, I prioritize the TV height.
Your seating situation is less than ideal to say the least. If I were you, I would invest in a decent chair that will benefit your desk setup and you can roll it to the middle of the room when watching TV.
