The Oxford Baby Dawson Toddler Guard Rail converts the Dawson 3-in-1 Island Crib into a toddler bed. Your child experiences the familiarity of the crib while gaining some independence. The Guard Rail provides extra security while still giving your little one the ability to climb in and out of bed on their own. The Guard Rail can be installed on either side of the crib, allowing you the freedom to design your toddler bed however you want.
