Inspired by the 19th century French sleigh bed style, the elegant Serenity Convertible Crib is constructed with solid wood for durability.This timeless beauty allows the flexibility to mix and match with cases from other Baby's Dream collections. Safety: Manufactured to the highest safety level, our products undergo rigorous safety tests and meet all regulations set by the U. S.Consumer Product Safety Commission (CPSC) and the JPMA (Juvenile Products Manufacturers Association). Quality: All Baby's Dream products are constructed of solid wood. This means no MDF, veneers, or particleboard. We build to be durable enough to last for generations. We even add extra thickness to our drawer bottoms and to restrict the possibility of stripping during conversions we use metal insert and bolt assembly. Value: Designed with cost savings in mind our convertible cribs will grow with your baby and last for years to come. No additional purchase is required to convert to toddler bed. Design: Our cribs offer 2-4 mattress levels, depending on model, ranging from 26 inches (highest position) to 9 inches (lowest position).This allows your baby to stay in the crib longer where he/she is comfortable.
