I thought these might have a non-slip backing so they would stay in place... Not only is that missing, but they actually have a slippery backing. They are pretty much worthless as far as I can tell. You could tape them down? I suppose. I bought these because my 4-year-old wets the bed sometimes and I thought it would make for easier cleanup. Halfway thru the night the pad was wrapped up and around his shoulder -- that's not likely to catch any pee. My son is a calm sleeper. For someone who tosses and turns or for any dog, these are beyond worthless. Not sure what they could be used for but this was wasted time and money for me.
