Bumper rails don’t fit on all beds, I found out the hard way. They are complicated and make changing sheets a bigger drag that it already is and worst of all, they are an eye sore. These Go Bed Bug bumpers are wedges that go right under the sheets and are super versatile. You can take these with you to grandma’s and easily switch beds when you need to. If I had known about this, I would have kept the queen bed in my tots’ room and had them share a bed – all I had to do to avoid them kicking each other was using these as dividers. I know you can probably find something similar at stores that sell back relieving supplies, but these are so well priced, you can avoid the hassle and guess work by just ordering these that are specifically designed as a bed guard. The one 42 inch piece is $12.95, two 27 inch pieces are $15.95 and the combo 42 inch piece + 21 inch piece are $19.50. At Go Bed Bug.
