Sorelle's Isabella 4 in 1 Crib is a lasting, special piece of your child's room and life, with the ability to be your child's bed from birth to college. Built of sturdy solid pine and finished with a warm, rich, traditional non-toxic Cherry, the Isabella is even environmentally friendly, constructed with water-based paints and odorless glue. You can not only rest assured in the crib's safety, but in the eco-friendly construction and Sorelle's reforestation policy. The Isabella grows with your child. Separately sold wooden conversion rails turn the crib into a toddler bed, the toddler bed into a day bed, and finally the day bed into a full-sized bed.
