Abstract

An ergonomic computer workstation comprises a base, a first vertical shaft supported by the base and a second vertical shaft for supporting a computer monitor thereon, connected to the first vertical shaft by means of a connection which permits vertical adjustment of the second vertical shaft relative to the first vertical shaft. The workstation further includes a keyboard arm for supporting a keyboard thereon. The keyboard arm is pivotally connected to the first or the second vertical shaft, preferably the first vertical shaft, and extends transversely therefrom. The keyboard arm comprises a first arm member which is connected to the vertical shaft at one end and a second arm member pivotally connected to the free end of the first arm. In one particular embodiment the workstation further comprises a monitor arm for supporting a computer monitor thereon pivotally connected to the second vertical shaft and extending transversely therefrom. The monitor arm comprises a first arm member which is connected to the vertical shaft at one end and a second arm member pivotally connected to the free end of the first arm member.

Claims
