The Fully Jax single-display, light-duty monitor arm is another of the many monitor arm options out there that you can use to add some ergonomic utility to your standing desk. It has some decent specs, being able to support a monitor up to 19.8 lbs and rotate 360-degrees. While it has a mechanical spring operation that is strong and long-lasting, that design also can feel a bit jerky and loud in its movements. On the other hand, this design also keeps it cheaper. It also has a height range a few inches shorter than the best competition that can limit its use for some taller users.
