Humanscale M2.1 Monitor Arm

In today’s fast-paced, agile work environment, there’s no time for discomfort. M2.1, part of Humanscale’s revolutionary new monitor arm line, instantly improves the comfort, health and productivity of any workspace. Fully compatible with traditional desks and sit/stand workstations alike, M2.1 meets a variety of configuration needs for lighter monitors up to 15.5 lbs. 

Featuring innovations like Humanscale’s patented Weight-Compensating Spring Technology and Smart Stop functionality, M2.1 enables the personalization and flexibility needed for today’s evolving workplaces.




Reduced Cost of Ownership

M2.1 features the lowest cost of ownership of any monitor arm, meaning it is the easiest, quickest, and most cost-effective, arm to install and modify for future moves, additions and changes to the workstation.  Its durable design also ensures the monitor arm won’t need to be replaced for many years. 

Sleek, Safe Design

M2.1’s Smart Stop feature allows the user to stop each joint anywhere along its rotation to prevent monitor or arm overhand on the desk edges. In addition, a built-in Counterbalance Indicator lets the installer counterbalance the monitor weight without a monitor. 

Unprecedented Flexibility

M2.1 is designed to keep desktops efficient and clutter-free now and in the future. Features include an Accessory Bracket, which supports document holders, headphone holders, whiteboards or whatever wire-shaped accessory you may require at your workspace. 

Simple and Sustainable

M2.1 ships unassembled to reduce packaging size and its modular links allow users to quickly design the most productive space without additional parts – all effectively saving resources, energy and shipping costs to get from factory to office. Humanscale monitor arms are also free of harmful Red List chemicals.

Integrated Technology

M2.1 is compatible with Humanscale’s revolutionary docking station, M/Connect 2, to eliminate desktop cables and provide a more streamlined workspace. It is also compatible with M/Power – a USB Type-A and Type-C charging station that offers convenient, high-speed charging for personal devices.
