Has anyone ever tried a 'standing desk'? I was reading about them online. Everyone who uses them says they are great after your body adjusts. Standing instead of sitting is supposed to yield great benefits in terms of core strength, posture, and general health. I just bought one of these risers to convert my current desk: http://www.lampsusa.com/index.asp?PageAction=VIEWPROD&ProdID=129592 While I wait to receive it I am using a couple of old LCD boxes laid flat to create a similar platform.
