The Rockwell 3-in-1 Toddler Bed Conversion Kit will transform your Contours Rockwell crib into a beautiful toddler bed for your growing child. The Toddler Rail provides the safety you want while still allowing easier access for your toddler to climb in and out of bed by themselves. And when your toddler is a little bit older, you can simply remove the Toddler Rail to convert your Rockwell crib into a day bed.
