Monitor arms free up desk space and improve ergonomics. But do you need a $150 Ergotron or will a $25 Amazon Basics arm work?

I tested 6 monitor arms to find out.

The $20-35 Range: Basic Single Arms

Best Budget: VIVO Single Monitor Arm

What you get:

• Holds up to 27" monitors
• VESA 75x75 and 100x100
• Gas spring adjustment
• Clamp or grommet mount

Check price on Amazon

The catch: Droops with heavy monitors (25+ lbs), cheap plastic joints

The $80-120 Range: Mid-Tier Quality

Best Value: AmazonBasics Premium Arm

Why it's better:

• Holds heavier monitors (32")
• Better gas spring (stays put)
• All-metal construction
• Smoother adjustments

Check price on Amazon

The catch: Still not Ergotron-level build quality

The $150-200 Range: Premium

Best Premium: Ergotron LX

Why it's worth $150:

• Holds up to 34" ultrawide
• Zero droop (even with heavy monitors)
• Lifetime warranty
• Smoothest adjustments

Check price on Amazon

The catch: $150. Only worth it for heavy/expensive monitors.

When Cheap Arms Work Fine

✅ Use budget arms ($25-35) if:

• Monitor is 24-27", under 15 lbs
• You don't adjust height often
• Budget is tight

❌ Don't use cheap arms if:

• Monitor is 32"+ or heavy (20+ lbs)
• Ultrawide monitor
• You adjust position frequently

What Actually Matters

Weight capacity

Check your monitor weight. Add 20% safety margin.

VESA compatibility

Most monitors use 75x75 or 100x100 VESA. Check before buying.

Gas spring quality

Cheap springs droop over time. Premium springs stay put for years.

Cable management

Built-in cable routing keeps desk clean.

Dual Monitor Arms

Best Budget Dual: VIVO Dual Arm

Check price on Amazon ($45)

Best Premium Dual: Ergotron LX Dual

Check price on Amazon ($280)

The Real Decision

Get VIVO arm ($25) if:

• Small monitor (24-27")
• First monitor arm
• Budget option

Check price on Amazon

Get AmazonBasics Premium ($100) if:

• 27-32" monitor
• Want better build
• Sweet spot quality

Check price on Amazon

Get Ergotron LX ($150) if:

• 32"+ or ultrawide
• Expensive monitor (protect investment)
• Want best quality

Bottom Line

Best budget: VIVO arm ($25)

Best value: AmazonBasics Premium ($100)

Best premium: Ergotron LX ($150)

Start cheap. Upgrade if it droops.
