Office Anti Fatigue Mats

The benefit comes from small constant movement, which a firm cushioned layer encourages and a thin mat does not, so thickness is the specification rather than the surface pattern. The safety detail people miss is the edge: a square-cut mat presents a lip to catch a toe, while a bevelled edge does not. Size it to where someone actually stands, not the whole bay. See sit-stand desks, footrests and chair mats.
