Your little ones will cruise to Dreamland in style with the Step2 Roadster Toddler-to-Twin Kids’ Bed. Mini car enthusiasts will love the details and styling made to look like the real thing! This children’s car bed will make sleep transitions fun. Start with the toddler-size bed using your crib mattress, which sits low to the ground and allows the car walls to act as extra support to keep little ones from rolling out. When your child is ready, add the front and side panels to expand to accommodate a twin-size mattress. Using a twin mattress only, the side walls continue to provide guardrail-like support. When guardrail support is no longer needed, you can add a box spring to raise the mattress higher. With this car bed for kids, bedtime becomes a treat rather than a chore!
