What is a gas-spring monitor arm vs. a mechanical spring arm?

A gas-spring arm uses a pressurized nitrogen cylinder to counterbalance the monitor weight — allowing one-touch height adjustment with effortless floating motion. A mechanical spring arm uses a coil spring and friction adjustment, requiring a tool (usually an Allen key) to re-tension when the monitor weight changes. Gas-spring arms are faster to adjust, more ergonomic, and feel more premium. Mechanical arms cost less. For workstations shared by users of different heights, gas-spring arms are strongly preferred.
