Abstract: An ergonomic keyboard support device for a computer keyboard having a substantially planar key upper plane, comprising a keyboard support having an operator-proximal keyboard support edge and a substantially planar keyboard support top surface; a support bar for maintaining wrist and forearm support during keyboard operations; and a computer mouse platform for holding a computer mouse and for writing by a keyboard operator and for maintaining wrist support during mouse operations. The support bar, which is connected to the top surface of the keyboard support across the operator-proximal keyboard support edge, has a substantially planar bar top surface. The mouse platform is movably positioned upon the planar top surface of the keyboard support and has a substantially planar top surface that is substantially in the same plane as the planar bar top surface. A wedge under the support platform upon a carriage plate connected to articulated linkage tilts the keyboard support at approximately 8.degree.
