Regalo Hide-Away Bed Rail gives added security with its length, which is about 56" long. You can sleep with the comfort and confidence of knowing your child is safe. The extra long bed rail is easy to unfold and rolls smoothly and tucks in easily between the mattress and box spring when not in use. This tucking feature makes it out of sight, which is why it is called the hide-away safety bed rail. Its simple functionality allows for hassle-free changing of bed sheets. Making the bed each day will be easier with the easy-to-use swing-down hinge.
