Our recommendation
This is the rare comparison where both products share DNA: the Amazon Basics arm is built by Ergotron. The LX has the better motion tuning, longer warranty, and nicer finish. The Amazon Basics arm delivers most of the experience for much less. Primary workstation: LX. Everywhere else: Amazon Basics. There is no wrong answer here, only a budget question.
Motion quality
The LX's patented Constant Force mechanism is smoother and more consistent across the full range of motion. The Amazon Basics arm uses good gas-spring motion, but side by side the LX feels more refined, with more even resistance and finer control. The gap is real but smaller than the price gap.
Warranty and finish
The LX carries Ergotron's long warranty and a polished aluminum finish. The Amazon Basics arm has a shorter warranty and a plainer look. Over a decade of use, the warranty difference matters; over three years, it mostly does not.
Price and value
The Amazon Basics arm typically costs substantially less than the LX. For secondary desks, kids' setups, or anyone price-sensitive, it is the rational choice. The LX justifies its premium on a primary workstation where you will feel the motion quality thousands of times.

- You want the longest warranty available
- Finish and refinement matter to you
Choose Amazon Basics Premium Single Monitor Arm if…
- You want Ergotron engineering for less money
- This is a secondary or kids' setup
- The warranty difference does not concern you
