Bests & Worsts Reviews from Amazon

I followed the instructions for this rail and dropped the mattress on top to find--not surprisingly--a huge bump in the mattress where the arms stretched across. It looked horribly uncomfortable so I pulled the mattress off, attached the arms underneath the springs, making sure the supplied velcro straps were nice and tight, and set the mattress back down again. No bumps. Nice and comfortable. After 3.5 months the velcro hasn't slipped or loosened at all, and that's with a crazy 3 year-old climbing over the rail and shaking it like a monkey in a cage. I couldn't be happier with this product. *UPDATE* - Now it's almost 2 years later and the velcro still hasn't slipped even a millimeter. If I could give this product 6 stars I would do so without hesitation!
