Ergotron WorkFit LX, Sit-Stand Desk Mount System

The Ergotron WorkFit LX Sit-Stand Desk Mount System is a premium height-adjustable workstation solution designed to convert any desk into an ergonomic sit–stand setup. Ideal for both home offices and professional environments, it enables seamless transitions between sitting and standing while providing precise control over the distance and height of your keyboard and monitor.

Featuring patented Constant Force™ motion technology, the WorkFit LX allows both keyboard and monitor arms to move smoothly and effortlessly, ensuring a stable data-entry platform and reducing strain on wrists, neck, and shoulders. The back-tilt keyboard tray offers a 5° ergonomic tilt when in use and folds upright 90° for compact storage. A slide-out mouse tray can be positioned on either side for personalised comfort.

The modular design lets users configure the system to meet specific workspace requirements, whether for a single monitor or dual monitor setup. With a compact footprint, the system fits perfectly in tight spaces, including corner desks, without compromising functionality. Integrated cable management features route cords under the arms, keeping your desk neat and organised.

The system includes a monitor arm, keyboard arm, two extensions, keyboard tray, slide-out mouse tray, desk clamp base, grommet-mount base, 48 cm pole, two pole collars, VESA brackets, and wrist rest, providing a complete ergonomic solution out of the box. All components have been quality tested with a 10,000-cycle lift mechanism test, ensuring years of reliable, trouble-free operation.

Locking connections between the arms, extensions, and base prevent accidental disconnections and add theft deterrence, making this sit-stand mount ideal for busy offices or shared workspaces. Users may require extra-long USB, power, or video cables to accommodate full height adjustments between sitting and standing positions.

Upgrade your workspace with the Ergotron WorkFit LX Sit-Stand Desk Mount System, a versatile, ergonomic, and height-adjustable workstation that enhances comfort, posture, and productivity while keeping your desk organised and flexible for any workflow.
