Innovative Design.


The M/Flex multi-monitor arm system allows the user to simply swap attachments to suit their changing technology needs while retaining a sleek, minimal aesthetic. Manufactured primarily from recycled aluminium, M/Flex is as recyclable as it is beautiful.

Greater Versatility.


M/Flex offers the most versatile, modular multi-monitor system available. By lifting up to six monitors – up to 9kg each – off the work surface, M/Flex frees up valuable desk space, helping to preserve the existing office aesthetics. M/Flex’s removable 180-degree stop also protects walls and panels.

Unparalleled Customisation.


M/Flex offers effortless adjustment and enables easy, spontaneous configurations. With its plug-and-play customisation, M/Flex allows users to add monitor arms, attachments and accessories as needed. M/Flex is the perfect addition to the modern and constantly evolving workspace and, when paired with the M/Connect monitor arm base, users can completely eliminate cable clutter and gain easy access to USB ports and high-speed charging.
