The BSF Baby Addison 4 in 1 crib offers an elegant design with striking accents. This crib is a beautiful addition to any nursery or children's room with a gorgeous finish and simple yet classic look. In the crib conversion you can adjust the mattress to three different support positions to maintain safety for your growing baby. This crib can be converted to a transitional bed for children who have outgrown their crib but still require the included safety bedrails. Once graduated from the transitional bed Addison can be used as a child's day bed until use of the full size headboard is needed. The headboard attaches to a standard bed frame to create a full size bed. Footboard can attach to the bed with adult rails not included but sold separately.
