Some say that sitting at a desk for eight hours a day or more can be bad for your overall health. If this is a concern for you, you might want to consider getting yourself a riser for your office or home desk. This contraption allows you to work at your desk while standing, as it provides a sturdy platform for a laptop or separate monitor, keyboard and mouse.
