Most monitor arm guides lump gas spring and mechanical spring arms together. That's a mistake. Gas springs offer something mechanical springs can't: one-finger adjustment that actually stays where you put it.
TL;DR: The Ergotron LX is the gold standard for gas spring arms—smooth movement, rock-solid build, 10-year warranty. On a budget? The NB North Bayou F80 has 22,000+ reviews and users report 4+ years without issues.
Not sure if gas spring is right for you? Our complete monitor arm buying guide covers the differences between gas spring and mechanical spring arms, plus how to check VESA compatibility and weight limits.

Our Top Picks
1. Ergotron LX – Best Overall
The Ergotron LX is the monitor arm that other brands benchmark against. It's not the cheapest, but it's the one you buy when you're tired of replacing budget arms every few years.
Why It Works:
- Automotive-grade gas cylinder: The same technology used in car hoods. Smooth, consistent tension that doesn't degrade like cheaper alternatives.
- 25 lb capacity: Handles virtually any single monitor, including heavy 32-inch panels that make budget arms cry.
- 10-year warranty: Ergotron actually stands behind this. Most budget brands offer 1-2 years at best.
The Catch: The price. You're paying premium for what is essentially a solved problem. If you're mounting a lightweight 24-inch monitor, this is overkill. Also, the cable management clips feel cheap compared to the arm itself—whoever designed those clearly had leftover budget to cut.
Who Should Skip This: Anyone with a monitor under 15 lbs who doesn't adjust their screen position frequently. You're paying for durability and weight capacity you might not need.
Best For: Users with heavy monitors, standing desk setups requiring frequent adjustment, or anyone who wants to buy once and forget about it.
Ergotron LX Desk Monitor Arm
Check Latest Price2. ErGear Single Monitor Arm – Best Budget
The ErGear punches way above its weight class. Aviation-grade aluminum, 22 lb capacity, and a price that makes you wonder what corners they cut. (Spoiler: mostly marketing budget.)
Why It Works:
- 22 lb capacity at this price: Most budget arms tap out at 17-19 lbs. ErGear gives you headroom for monitor upgrades.
- Aviation-grade aluminum: Not just marketing speak—the arm feels genuinely solid, not the hollow plastic-y feel of some competitors.
- 20,000+ cycle testing: They claim 10+ years of daily adjustments. Time will tell, but the engineering seems sound.
The Catch: It's a newer brand with less long-term data. The 4.5-star rating across 986 reviews is promising, but we don't have the 4+ year reliability reports that NB North Bayou has. Also, the instructions assume you've assembled furniture before—first-timers might struggle.
Who Should Skip This: If you need absolute certainty about 5+ year reliability, spend more on the Ergotron or go with the battle-tested NB North Bayou.
Best For: Budget-conscious buyers who want premium specs without premium pricing, and don't mind being an early adopter.
ErGear Single Monitor Arm
Check Latest Price3. NB North Bayou F80 – Best Value
The NB North Bayou F80 is the people's champion. With 22,000+ reviews and users reporting 4+ years of trouble-free use, it's the most battle-tested budget option available.
Why It Works:
- Massive user base: 22,148 reviews means real-world data, not marketing claims. When this many people agree something works, it probably works.
- Proven longevity: Multiple forum users report 4+ years without sagging or issues. That's rare for budget gas springs.
- Full motion range: -30° to +85° tilt, 360° rotation, 90° swivel. Everything you need for ergonomic positioning.
The Catch: The warranty situation is murky. NB is a Chinese brand, and while the product is solid, getting warranty service can be a headache. One forum user put it bluntly: "Great arm, just don't expect customer service if something goes wrong." Also, the finish isn't as refined as Ergotron—you'll see some rough edges if you look closely.
Who Should Skip This: If warranty support matters to you, or if you're particular about fit and finish. The Ergotron's polish is noticeably better.
Best For: Value hunters who want proven reliability without paying the Ergotron tax. Perfect for "set it and forget it" users.
NB North Bayou F80 Monitor Mount
Check Latest Price4. HUANUO Single Monitor – Best for Beginners
The HUANUO is designed for people who've never installed a monitor arm before. The "3-minute installation" claim is actually realistic, and the instructions are clearer than most competitors.
Why It Works:
- Genuinely easy setup: One-piece design means fewer parts to juggle. Most users report 3-5 minute installation without help.
- Forgiving tension adjustment: The gas spring tension is easy to dial in, even if you're not sure what you're doing.
- Solid build quality: 20,000 motion tests, automotive-grade components. HUANUO isn't cutting corners where it matters.
The Catch: The 19.8 lb weight limit is on the lower end. If you're planning to upgrade to a 32-inch monitor later, you might outgrow this arm. Also, the desk clamp maxes out at 3.54 inches—thick desks need not apply.
Who Should Skip This: Anyone with a monitor over 18 lbs, or plans to upgrade to a heavier display. The weight headroom is tight.
Best For: First-time monitor arm buyers, lighter monitors (24-27 inch), and anyone who values easy installation over maximum specs.
HUANUO Single Monitor Mount
Check Latest Price5. VIVO Premium STAND-V001Q – Best Premium Build
The VIVO Premium splits the difference between budget arms and the Ergotron. Full aluminum construction, smooth gas spring action, and a price that doesn't require justification to your accountant.
Why It Works:
- Full aluminum construction: No plastic joints or hollow sections. The arm feels substantial and looks premium on your desk.
- Smooth counterbalance: The gas spring provides that "floating" feel where the monitor stays exactly where you put it.
- 32-inch compatibility: 20 lb capacity handles most monitors without strain.
The Catch: At this price point, you're closer to Ergotron territory without the Ergotron warranty or brand reputation. The value proposition gets fuzzy. Also, the C-clamp only fits desks up to 3 inches thick—check your desk before ordering.
Who Should Skip This: If you're spending this much, consider stretching to the Ergotron for the warranty and proven longevity. Or save money with the NB North Bayou if you don't need the premium aesthetics.
Best For: Users who want that premium full-aluminum look without paying Ergotron prices. You're trading warranty length for aesthetics—if that's a fair trade for you, this is your pick.
VIVO Premium STAND-V001Q
Check Latest PriceGas Spring vs. Mechanical Spring: Quick Comparison
| Feature | Gas Spring | Mechanical Spring |
|---|---|---|
| Adjustment Feel | Smooth, one-finger | Stiffer, requires more force |
| Longevity | Can sag over years | Maintains tension longer |
| Price | Generally higher | Generally lower |
| Best For | Frequent adjusters | Set-and-forget users |
If you adjust your monitor position multiple times per day (standing desk users, take note), gas spring is worth the premium. If you set your monitor once and never touch it, mechanical springs work fine and may last longer.
Frequently Asked Questions
Do gas spring monitor arms sag over time?
Yes, gas springs can lose pressure over years of use. Higher-quality arms like Ergotron use automotive-grade gas cylinders that maintain tension longer. Budget options may start sagging after 2-3 years of heavy use.
What's the difference between gas spring and mechanical spring monitor arms?
Gas springs use compressed nitrogen for smooth, counterbalanced movement. Mechanical springs use metal coils that require more force to adjust. Gas springs feel more premium but can sag; mechanical springs last longer but feel stiffer.
How much weight can a gas spring monitor arm hold?
Most gas spring arms support 4.4-22 lbs. The Ergotron LX handles up to 25 lbs, while budget options like ErGear max out at 22 lbs. Always check your monitor's weight before buying.
Are gas spring monitor arms worth it for standing desks?
Yes. Gas springs make height adjustments effortless—you can reposition your monitor with one finger. This is especially valuable when switching between sitting and standing throughout the day.
Can I use a gas spring arm with an ultrawide monitor?
It depends on the weight. Most 34-inch ultrawides weigh 15-20 lbs, which standard gas spring arms can handle. For 38-inch or larger ultrawides, consider heavy-duty monitor arms designed for heavier displays.
What about wall mounting?
If you want to free up desk space entirely, wall mount monitor arms are a great alternative. They eliminate desk clamp wobble and work well with standing desks.
