I just changed my desk from a more traditional desk to a standing desk. I wanted a standing desk for a while, but the prices are extremely high. I was looking around my room and noticed the old rolling shelf I used to keep animals on when I was teaching science. Brainstorm!
Since the shelves are adjustable I can move them up or down as needed. This also gives me a lot of flexibility because I can literally wheel my desk anywhere in the building just by unplugging the electric and internet cable.
