It optimizes desk space while promoting an ergonomic posture by allowing users to easily adjust the height, tilt, and viewing distance of their display.

Advantages

This premium office monitor arm features an advanced gas spring mechanism that enables smooth and effortless height adjustment without the need for tools. It accommodates both flat and curved screens up to 20 kg and supports VESA standards of 75x75 and 100x100 mm. The flexible arm design includes three pivot points for optimal viewing angles, alongside a 360-degree rotation capability and a practical 180-degree rotation lock mode to prevent the screen from colliding with backwalls or adjacent monitors. The top-side mounting system ensures simple installation and a clean, organized aesthetic, complemented by an integrated cable management system to keep wires out of sight.
