Constant Force spring technology lets you reposition your screen with literal fingertip pressure. Tested to 10,000 cycles with a 10-year warranty.
Most cheap monitor arms use pneumatic gas springs that slowly leak oil and start sagging after two years. The Ergotron LX uses a heavy mechanical spring system called Constant Force. You literally take one finger, push your monitor up 4 inches, and let go. It stays there with zero bounce and zero sag. I have rotated my monitor from landscape to portrait thousands of times while reviewing code, and the pivot joint feels as tight as day one. It is an investment that outlasts three computer monitors.
Currently priced at $189.95 (regularly $219.95) on Amazon, the Ergotron LX Desk Mount LCD Monitor Arm, Polished Aluminum represents a proven, high-ROI investment in your posture and daily focus.
