Quick answer: Gas spring arms use a pressurized cylinder for smooth, tool-free height adjustment and handle heavier monitors reliably over time. Friction arms use tightened joints for a simpler, cheaper mechanism, best suited to lighter monitors that aren't repositioned often.
Side-by-Side Comparison
| Factor | Gas Spring Arm | Friction Arm |
|---|---|---|
| Adjustment feel | Smooth, one-finger | Requires pushing against resistance |
| Weight capacity | Higher, often 15-33 lbs | Lower, typically 4-20 lbs |
| Long-term stability | Consistent, minimal drift | Can loosen with repeated use |
| Price | Generally higher | Generally lower |
| Maintenance | None needed typically | Occasional tension screw tightening |
How Each Mechanism Actually Works
Gas spring arms contain a sealed cylinder filled with pressurized gas (usually nitrogen) that pushes back against the monitor's weight, creating a counterbalance. This means the arm holds position at any point in its range without needing to be manually tightened, and adjustment feels smooth and consistent regardless of how many times you've moved it.
Friction arms rely on tightened bolts, washers, and joints creating enough resistance to hold the monitor's weight in place. Moving the arm means physically overcoming that resistance, and the resistance itself can loosen gradually through repeated use, requiring periodic retightening with a hex key or screwdriver to restore firm holding power.

Choosing Based on Your Monitor's Weight and Usage
If your monitor is on the heavier side (roughly 15 lbs or more, common for 27-32 inch and ultrawide displays) or you adjust its position frequently throughout the day, a gas spring arm is the more reliable long-term choice, since it's built to handle sustained adjustment without the mechanism wearing down.
If your monitor is lighter (under 15 lbs, typical for 19-24 inch displays) and you rarely reposition it after initial setup, a friction arm is a reasonable, more affordable choice, as long as you're willing to occasionally retighten the tension screw if it starts to droop after months of use.
Frequently Asked Questions
What's the difference between a gas spring and friction arm monitor mount?
A gas spring arm uses a pressurized cylinder to counterbalance the monitor's weight, allowing smooth one-finger height adjustment that holds position without tightening anything. A friction arm relies on tightened joints and washers creating resistance, requiring manual tightening to hold position and adjustment by pushing against that resistance.
Which is better, gas spring or friction arm?
Gas spring arms generally provide smoother, easier adjustment and handle a wider weight range without loosening over time, while friction arms are typically cheaper and adequate for lighter monitors that aren't adjusted frequently.
Do gas spring arms need maintenance?
Gas spring arms rarely need adjustment since the cylinder is factory-set for a specific weight range, though some models include a tension dial to fine-tune within that range. The gas cylinder itself isn't user-serviceable and typically isn't refillable if it loses pressure after many years.
Why does my friction arm monitor mount keep drooping?
A friction arm droops when the tension screws loosen over time from repeated adjustment or when the monitor's weight exceeds the arm's rated capacity. Most friction arms have an adjustable tension screw (often a hex bolt) that can be tightened to restore holding power, though repeated over-tightening eventually wears out the friction washers.
Can I use a friction arm for a heavy 4K or ultrawide monitor?
Only if the friction arm is specifically rated for that weight, since heavier monitors need proportionally more tension to hold position, which increases wear on the friction mechanism faster. Gas spring arms are generally the safer choice for monitors over roughly 15-17 lbs.
