Query: awesome - stays in place and does the job!!!

These are the best bed rails out there. We have used them for three years, secured between a queen mattress and boxspring. It stays in place and never moves. It is not too difficult to put in place and there is no room for a child to fall between the mattress and rail, if installed correctly. When in place, it folds down more than 90 degrees to make it easy to change the sheets. We are buying two more for each side of a twin bed now!!!!!
