In many ways, a keyboard support is the heart of an ergonomic workstation. As reach and vision drive posture, an articulating keyboard system allows the user to sit in a healthy, neutral posture through bringing the keyboard and mouse to the user. A well-designed articulating keyboard system offers protection from carpal tunnel syndrome, neck and back pain and other musculoskeletal issues. Since 1999, Humanscale has been the leading manufacturer of articulating keyboard systems and today sells more than all other manufacturers combined.
"A decade of ergonomic research shows that using a negative sloped adjustable keyboard tray maximises the time spent working in a neutral hand, wrist and upper body postures. These postural benefits can’t be achieved by just using a keyboard on a height-adjustable work surface."
