This LX Sit-Stand Arm provides a very stable platform for a keyboard and mouse; tested to be 3x more rigid than other keyboard arms. The keyboard tray’s leveling mechanism allows the surface to be perfectly flat no matter where the keyboard is positioned.

    The LX's patented CF motion technology provides premium ease-of-use adjustment. Ergonomic back-tilt keyboard tray ensures wrists remain in a neutral position during data entry, helping the user avoid repetitive-stress injuries while increasing comfort and productivity.
