This stunning mobile is made of highly reflective paper in the shape of people and is designed to move and mirror light in a captivating way. We recommend introducing this mobile to your child from 10 weeks, helping to build visual skills and support tracking and concentration. While each mobile is made with attention to Montessori principles and precise proportions, some minor individualised adjustment may be required to balance the octahedron and dancers mobiles once mounted on your particular play gym frame. Please don’t hesitate to reach out to us with any questions regarding optimal adjustment. Please note our supplier has recently changed and now each of the mobiles have clear rods rather than wooden ones. We are in the process of updating the current pictures on our website and we thank you for your patience while we update our website to reflect the changes.
