An ergonomic arm support for supporting the forearm during typing, keying, or assembly operations. The arm support includes an armrest pivotally mounted on a shroud for sliding the armrest to and away from a cantilever disk which is secured to a table or chair. The shroud is pivotally slidable or repositionable relative to the cantilever disk such that the armrest, which is pivotal relative to the shroud may be positioned to provide a wide range of locations for positioning of an individual's forearms. The cantilever disk permits easy or convenient inward, outward, forward, or backward positioning of an armrest relative to an object where the cantilever disk frictionally engages the shroud to lock the armrest into a desired position during use. The shroud may also function as an enclosure of the cantilever disk to prevent inadvertent engagement between an individual and/or the individual's clothes and the cantilever disk.
