The journey from crib to “big kid” bed is easy to plan for with the Concord Baby Metro 4-in-1 Baby Crib. Bringing a modern aesthetic to the nursery, it showcases a symmetrical silhouette that looks smart in the center of a room or against a wall. Designed to grow with your child, the convertible crib features a mattress that adjusts to six different heights and converts to a daybed, toddler bed and full-sized bed (toddler rail and full-sized bed frame sold separately).
