Keyboard Trays: Alignment issues

Although keyboard trays have many benefits by adjusting the keyboard and mouse to a comfortable position (relative to height and distance), due to its limited surface area, the keyboard's alphabetical keys are usually shifted to the left.
This off-center position may cause postural shifting and the potential for irritation.

If this is the case shift the chair slightly left and then reposition the monitors slightly left also.
