Glad to help. BTW, this is what my desk looks like now if you want some ideas.

I use one at home (I built an elevated stand that sits on top of my normal desk). I get to work from home two days a week -- when I'm at the office I sit though. I would think you could justify a standing desk by citing ergonomic concerns. A lot of companies make an effort to meet the ergonomic needs of their employees. You may even take this up with HR as well. On thing I will say is that a standing desk is no replacement for physical movement. I try to take a walk around our building after lunch every day, and get up frequently to stretch my legs. A standing desk keeps the blood flow unhindered but physical activity keeps circulation high. Good luck!
