The Regalo Swing Down Bed Rail is ideal for children transitioning to their first bed. This secure, mesh-covered protective rail prevents your child from accidentally rolling out of bed. Standing 20" (51 cm) high, it accommodates thick mattresses and extends 43" (109 cm) for enhanced security. The bed rail conveniently swings down and out of the way when not in use, or for convenience when your child is entering or exiting the bed. The steel frame construction ensures stability and reliable everyday use.
