My family and I do a good amount of traveling. So, when we were looking for a rail for our daughters bed once we converted it we were surprised to find this portable one. It is as easy as you could possibly get to install one. And its size was great for her still crib sized mattress. But it can also be used with a larger mattress like when she stays at grandma's or her aunt's house. She especially likes to cuddle up against it and she can do that because it is soft. I think she sees it as a body pillow while my husband and i like the security it provides us knowing it is keeping her safe in her bed. I was even able to sew a custom cover for it to match her other room decor so it really blends in with her furniture quite well. The price was a little more than we really wanted to pay for this sort of item, but looking back we're glad we did. I woudl say if you're not sure about whether or not to purchase this item, take the plunge!
