The specially mentioned refugee camps who often come with no money or supplies and only the clothing on their back. Or disasters where people gather in haste with no access to supplies as infrastructure has been destroyed. The logistics of sending larger mats is also harder. These can be made with existing facilities in any large city and deployed almost immediately. Of course there are better options or even sleeping on the floor would work in a pinch.
