The Regalo HideAway Double-Sided Bedrail provides a safe, comfortable way for your toddler to graduate from a crib to an adult-sized bed. Designed with sturdy steel construction, the double-sided bedrail can be set up in minutes and provides a snug fit without any gaps between the rail and mattress. The patented Hide Away feature allows the bedrail to conveniently fold down and slide between the mattress and box spring when not in use.
