I'm laughing at diamond spinning around in her chair. If I were to do that, I'd break something, or myself...lol.

My PC is sitting on an executive office desk, way too high for computer use, but it's all I have. The chair is an adjustable without armrests, and it is at the lowest position possible - I am 5'1/2" tall, so I keep it low. In the knee well, I have a riser (which is really too tall) that I prop my feet on, if I'm not sitting on them, or don't have them propped on the lower right file drawer. It's a very bad set-up, IMO, but all I have in this dinky little place we call our home.
