Best Monitor Arms of 2025: Complete Review & Buying Guide

Most monitors ship with a basic stand that sits too low, takes up precious desk space, and offers zero adjustability. If you’ve ever stacked books under your screen just to get it to eye level, you already know the problem.

A good monitor arm solves all of this. It lifts your screen to the correct ergonomic height, frees up the entire footprint under your monitor, and lets you swivel, tilt, or even rotate your screen with one hand. In this guide, we tested and compared the 6 best monitor arms of 2025 — from $30 budget picks to $150 premium arms.

What to Look For in a Monitor Arm

Single vs. Dual vs. Multi-Monitor

A single arm handles one monitor and is the simplest, most stable option. A dual arm uses a central pole or two separate arms to hold two screens side by side — ideal for productivity setups. Some dual arms are fixed to a single pole, while others let you adjust each arm independently. For three or more monitors, look for modular pole systems that let you stack arms.

Gas Spring vs. Mechanical Spring vs. Fixed Pole

Gas spring arms use a pneumatic cylinder to counterbalance your monitor’s weight, letting you move the screen up, down, forward, and back with a fingertip touch. They’re the most adjustable and satisfying to use, but they cost more and require careful weight-range tuning. Mechanical spring arms work similarly but use tension springs instead of gas — they’re cheaper but can feel slightly less smooth. Fixed pole mounts are the least adjustable: the arm slides up and down on a pole and locks in place with a clamp. They’re simple, affordable, and reliable but don’t offer the dynamic repositioning that gas arms do.

VESA Compatibility

VESA is the mounting-hole pattern on the back of your monitor. The standard is 75×75mm (smaller monitors) or 100×100mm (most 24"–32" screens). Almost every monitor arm supports both, but always check your monitor’s VESA pattern before buying. Some ultrawide or curved monitors use non-standard VESA patterns and may need an adapter bracket.

Weight Capacity

Every arm has a rated weight range. Go under the minimum and the arm won’t stay down (it’ll float up); go over the maximum and the arm will sag or fail. Most single arms support 4.4–20 lbs, which covers 24"–32" flat panels. Curved and ultrawide monitors can push 25+ lbs and need a heavy-duty arm. Gas spring arms have a tension adjustment screw — dial it to match your monitor’s exact weight for smooth movement.

Clamp vs. Grommet Mount

Most arms include both mounting options. A C-clamp attaches to the edge of your desk (works with desks up to 2–3" thick) — the easiest to install and the most common. A grommet mount goes through a cable-management hole in your desk for a cleaner look. If your desk has no lip and no grommet hole, some arms offer a freestanding base (rare, but available).

Cable Management

A good monitor arm hides the power and video cables inside the arm itself, keeping your desk clutter-free. Look for arms with built-in cable channels with removable covers — some budget arms route cables through exposed clips that can snag when you adjust the screen.

MOUNT PRO’s dual gas spring mount is the dual-monitor equivalent of a premium single arm. Each arm has an independent gas spring mechanism rated for 17.6 lbs, and the full articulating design means you can pull one monitor forward for focused work while keeping the other at reference distance.

FAQ

Will a monitor arm work with my monitor?

Almost certainly yes. The vast majority of monitors made in the last decade have VESA mounting holes — either 75×75mm or 100×100mm. Check the back of your monitor for four screw holes in a square pattern. If your monitor doesn’t have VESA holes (some budget Samsung and LG models don’t), you can buy a VESA adapter bracket for $15–$25 that clips onto your monitor’s chassis. All the arms in this guide include VESA plates and screws for both 75mm and 100mm patterns.

Is a gas spring arm worth the extra money over a mechanical pole arm?

Yes, if you adjust your monitor position frequently. A gas spring arm lets you pull your screen closer for focused work, push it back when you’re leaning in your chair, raise it when you stand, and swivel it to show someone else — all with one hand and zero tools. A mechanical pole arm locks in one position and stays there. If you set it once and never move it (common in a fixed desk setup where only you use the workspace), a pole arm is perfectly fine. If you share your desk, alternate between sitting and standing, or frequently reposition your screen, the gas spring premium is worth every dollar.

Can I mount a curved or ultrawide monitor on a monitor arm?

Yes, but you need to watch the weight. Curved and ultrawide monitors are heavier than flat panels of the same diagonal size — often 15–25 lbs. The Ergotron LX and Amazon Basics arms handle 25 lbs and work well with most 34" curved ultrawides. The HUANUO gas spring arm supports 26.4 lbs. For larger 38"–49" super-ultrawides (30+ lbs), you’ll need a heavy-duty arm rated for 33–44 lbs, which typically costs $200+. Always check your monitor’s weight without the stand before buying an arm.

Can I use a monitor arm on a standing desk?

Yes — monitor arms pair beautifully with standing desks. The combination is ergonomic gold: your desk adjusts for your standing height, and your monitor arm fine-tunes the screen position independently. One caveat: check your standing desk’s thickness and edge profile. Most arms clamp onto desks up to 2–3" thick. If your standing desk has a thick frame, a beveled edge, or a support bar near the back, verify clearance before buying. All the arms in this guide include grommet mounts as an alternative for tricky desk edges.

How hard is it to install a monitor arm?

Most single arms take 15–20 minutes with a screwdriver. The process: attach the clamp to your desk, slot the arm onto the pole, bolt the VESA plate to your monitor, and clip the monitor onto the arm. Dual arms take longer (25–40 minutes) because you’re mounting two monitors and balancing two arms. The trickiest part for gas spring arms is dialing in the tension — you’ll need to adjust a screw with an Allen key until the arm holds your monitor without floating up or sagging down. Every arm in this guide includes all necessary tools and hardware.

The Bottom Line

• Best overall: Ergotron LX — unmatched build quality, 10-year warranty, and gas spring action so smooth it makes other arms feel broken. The premium choice that will outlast your next three monitors.

• Best Ergotron alternative: Amazon Basics Single Monitor Arm — identical internals to the Ergotron LX at $30–$40 less. Buy this if you want the best and don’t care about the logo.

• Best value gas spring: HUANUO Gas Spring Monitor Arm — 85% of the Ergotron experience for 40% of the price. Smooth, sturdy, and includes a USB passthrough.

• Best budget: VIVO STAND-V001 — $30 and 10 minutes to install. Basic, but it gets the job done for lightweight monitors.

• Best budget dual: WALI Dual Monitor Arm Mount — two fully independent arms for under $75. The productivity-per-dollar champion.

• Best premium dual: MOUNT PRO Dual Gas Spring Mount — gas spring smoothness on two arms with quality enclosed cable management. The dual-monitor setup you’ll actually enjoy adjusting.

A monitor arm is one of the highest-impact ergonomic upgrades you can make — it costs less than a standing desk, takes less space than a chair, and immediately fixes the most common posture problem: looking down at your screen. Whether you spend $30 or $150, getting your monitor to eye level is a win your neck and shoulders will feel by the end of the first day.
