The central core of the room is the cot, a flexible sleeping place that adapts to a child as it grows. At the same time, the bed serves as a safe retreat for the child. For games and explorations, elements are used which promote and challenge the child’s development. Closeness is very important for parents and child, therefore the cot should be able to wander through the rooms with the child. Based on this, a multifunctional changing unit and a wardrobe were designed to accommodate the growing functions. Parents should be able to use and rearrange the furniture in a time-saving way by using functional components.
