In regards to Carpal Tunnel, I find that if your elbows are positioned higher than your wrist, then there is little or no discomfort on the wrists, because your arm lifts your wrists up.
This can be achieved by positioning the chair at a high position.
The monitor will be lower, but this can be adjusted with a monitor stand/mount/monitor table.
Conversely, if you let your wrist slouch and your elbow is lower than your wrist, the weight of your lower arms drag your wrists and forces your wrists to support the weight of the lower arms.
Just something I think helped A LOT in the comfort (or lack thereof) of my wrists.
This process also applies to the mouse and mouse pad.
