The Best Monitor Arms in 2026: Free Up Your Desk

A monitor arm is the cheapest way to make a desk feel twice as big. It clears the footprint of a monitor stand, lets you push the screen back for better viewing distance, and raises it to a posture-friendly height instead of forcing your neck down. The category is mature in 2026, and a few arms keep topping the lists for good reason. Here is how to choose.

The best for most desks: Ergotron LX

The Ergotron LX is the arm reviewers recommend by default. Its patented CF spring mechanism makes height and tilt adjustments smooth and one-handed, it carries a 10-year warranty, and it handles monitors up to 34 inches and 25 lbs. It is the rare product that is both the safe choice and a genuinely good one.

The smooth splurge: Herman Miller Flo

If you reposition your monitor throughout the day, the Flo’s mechanism is the smoothest in the category — a light nudge moves the screen and it holds. It is a premium pick at a premium price, but for people who are picky about feel and adjust often, it is the one that earns the upgrade.

For heavy and ultrawide monitors: Ergotron HX

Big ultrawides and 4K panels can exceed a standard arm’s weight limit, which leads to sag and drift. The Ergotron HX is built for exactly this — it is the go-to for ultrawide displays and even TVs used as monitors, holding far more weight than the LX while keeping the same build quality.

The budget dual-monitor pick: VIVO dual arm

Two screens on stands eat an entire desk. The VIVO dual arm mounts both on a single steel pole, handles monitors up to about 30 inches each, and costs a fraction of premium arms. It is not as buttery as an Ergotron, but for a two-screen setup on a budget it is the easy recommendation.

Bottom line

The Ergotron LX is the right arm for most people, the Herman Miller Flo is the splurge for constant repositioners, the Ergotron HX is the answer for heavy and ultrawide screens, and the VIVO dual arm clears two monitors off the desk on a budget. Check your monitor’s VESA pattern and weight before buying any of them.
