The FitDesk sit-to-stand desk is affordable ($259.99) and super easy to assemble. If I can do it, you can! I like the sleek look and cord control basket. I used this one on my screened-in porch for the fall and spring when I wanted to work outside. When I was done, I would just roll it out of the way.
