I've gotten quite a few questions about my standing desk project, so I thought I'd write up a post about it. I built it on top of my existing desk using these parts that you can buy from Ikea. I actually bought them direct from their website. With shipping and tax, I spent less than $50. The only addition I made is that I also zip tied the brackets to the legs using some heavy duty ones from Lowes that we had left over from my baby gate project. I am only a few days into standing at this point, but I love it. I also purchased an anti-fatigue mat as my office has hard floors.
