The ergonomic design of the newly developed cocoon embraces your newborn in comfort. You can use it from birth up to 18 months. During the first 6 months, the mattress can be used in a lie-flat position to provide extra back support. The instant your little one can sit up, the cocoon can be used in a sitting position too. A warm summery day? The front allows a flow of fresh air to control your baby?s temperature naturally. Traveling by car? Simply fold the cocoon together with the stroller, and off you go.
