The Fully Cooper is the answer to a specific question: what if Ergotron-grade build quality came in a silhouette that disappeared into the desk? After 8 months mounting our main 27″ we confirmed it does.
The joints feel premium
Every pivot on the Cooper is dampened — no sudden drops, no over-correction. The gas-spring counterbalance holds monitors from 4-20 lb without re-tensioning. Ergotron’s LX is the only arm we’d rate higher for motion feel, and the Cooper undercuts it by $60.
Clean cable channel
The rear cable routing is a continuous aluminum channel that actually closes — unlike the snap-clip clutter on most budget arms. Your HDMI + USB-C + power cables run inside the arm to a hidden exit near the grommet. Zero cable sag, zero visual noise.
Warranty caveat
5-year warranty is less than Ergotron (10) or Herman Miller Ollin (10). For a monitor arm this is usually enough — they rarely fail — but worth knowing if warranty-length is a tiebreaker.
Bottom line: The minimalist monitor arm pick at $139. Buy it if the Ergotron LX is out of budget or aesthetically too busy for your setup.
