Bests & Worsts Reviews from Amazon

Have a 26ft travel trailer with 1 slide out. When my kids moved in their bunks, I moved in my bed and it drove me nuts! I put a 4in foam top with a pillow top on my mattress, that didn't help at all. I did 2 camping trips now with these. First on dirt and second on grass. I bought 2. I put 1 under the rear bumper and at first the other 1 under the slide out.. that didn't work as expected. So I moved the 1 from the slide out to the front by the tongue. Which is almost under the master bed. HUGE difference! So 1 under the bumper and 1 under the tongue works awesome for us. When I get the money, I'll be buying 2 more so all 4 sides will be covered. It doesn't stop the movement completely, but it makes a really big difference. I don't feel my kids rolling around anymore. And if someone is walking around, you move a second but you don't keep rockin'. I won't set up camp without them.
