My wife and I have a wooden floor, a French bed and a slightly large bed frame in the bedroom. Our bed slid a lot when we did. em. exercises in the bedroom. I've tried grip mats, pads etc and they all seemed to wear out and stopped working within a week. We have had these floor mats for 2 weeks and are trying to have another baby. So they were definitely put to the test and our bed didn't budge an inch. These things really work to hold your furniture in place, which tends to shift around a lot.
