I wanted a sit-stand workstation because I spend ridiculous amounts of time on my computer and am the restless sort, so being able to change positions and maintain proper alignment while I fidget around is a real boon to ergonomics. I’ve made makeshift sitting and standing desks for years, from kitchen counters to book piles to a strategically placed empty dresser, but no matter how well I set them up, a static desk just didn’t seem right.

The past few years of experimentation did teach me about how one should be aligned in both sitting and standing positions, though.
