DESC: The Simplicity Ellis 4-in-1 Crib offers long-lasting value, versatility and style for your child's bedroom. The unique 4-in-1 sleep system converts the crib into a transitional bed, a day bed and a full-size headboard. Crafted of sturdy hardwood, the Ellis crib features a clean, contemporary design in a light natural finish. A 4-position metal mattress support provides comfort and safety as your baby grows and uses a standard crib mattress (not included). The transitional bed is designed for toddlers and includes bedrails. Convert the Ellis into a day bed that doubles up as a couch or extra bed to accommodate an occasional overnight guest. The Ellis also serves as a full-bed headboard that uses a full-size mattress, box spring and frame (not included) when your child is older. Crib should be converted to a transitional bed once your child reaches the height of 35" (90cm) or becomes too active and is able to climb out.
