Made of solid European Beech wood, the Stokke® Sleepi™, designed in 1999 by Susanne Grønlund and Claus Hviid Knudsen, accommodates the changing needs of a growing child. The bed has a soft oval shape to give the baby a sense of security - resembling a mother’s womb. The bed can be used from birth to 5 years. It comes with height adjustable mattress positions to offer safety and flexibility for each age and stage of development. The soft, breathable mattrress ensures continuous airflow, and meets the highest safety standards.The lockable swivel wheels function allows a 'rocking motion' to promote sleep and to keep the bed close to the parent. Once the child attains a specific age, the wheels and one side on the bed can be removed for added convenience.
