This Montessori-inspired wave-shaped stacking toy from PlanToys invites open-ended exploration with mix-and-match pieces that are satisfying to grip. Without a central pole, children can stack freely, experimenting with balance and sequencing. The included bell ball enhances auditory development, encouraging focus on sound. Waves interlock in multiple ways—vertically and horizontally—fostering problem-solving, logical thinking, and fine motor skills. Each ring features a center hole for added threading play. 

Ages 5 months & up.
