For the last two weeks I've been testing the UpDesk PowerUp standing desk. If you're looking for one of the best powered standing desks, then you should definitely take a look at what these guys offer.
This particular desk is the large version featuring a 72" high quality laminate top, and a motor that makes the desk rise and lower quickly. It's not cheap, but it does come with a 5-year warranty, and the build quality is excellent.
Having the option to stand has changed the way I work for sure. It's especially useful when doing long YouTube video editing sessions with Final Cut Pro X on my Mac. Check out my full review of the UpDesk Power Up for more details.
