Your baby's transition from crib to bed will be a cinch with Argintgon's easy-to-assemble toddler conversion kit. The kit converts the crib into a toddler bed while using the existing crib mattress. This extends the use of your crib while providing a safe changeover for your toddler. Conforms to and exceeds all regulations set forth by ASTM, Consumer Product Safety Commission, and Health Canada.
