PlanToys Montessori-Inspired Ball & Wave Stacker

PlanToys Montessori-Inspired Ball & Wave Stacker 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 centre hole for added threading play. Set includes: 1 ball and 3 wavy rings. Encourages hands-on learning through free-form stacking, building focus and coordination. Supports self-correction and problem-solving as children balance curved pieces without a central rod. Offers a calm, engaging play experience through its simple, natural design. Sustainably made in Thailand using chemical-free rubberwood, non-toxic glue, organic pigments, and water-based dyes. Set Includes: 1 ball and 3 wavy rings. 7 cm X 7 cm X 2.4 cm.

Designed for curious hands, this beautiful wave stacker is ideal for tabletop invitations, mindfulness corners and early STEM provocations. Children can explore how the curved shapes sit, slide and rock against each other, listening for the gentle sound of the bell ball as they roll, stack and tilt. The open-ended design encourages experimentation, persistence and quiet discovery, making it a lovely addition to natural play spaces in childcare settings.
