I'm curious what HN, particularly the standing desk and ergonomics nerds, thinks about this statement?<p><i>Turns out, humans aren’t really designed to stand for long periods with feet flat on the floor. This contributes to stress on the spine, and you can feel it in your lower back. A foot rail allows us to redistribute the load on our feet—first one foot, then the other—and alter the tilt of our spines.</i>
