The infant/toddler Rock-a-Stack toys are made from durable plastic. The adult inflatable Rock-a-Stack costume is made from 100% polyester.

The large version includes six colorful rings for grasping, shaking, stacking and rattle play. The drop-through activity version includes five colorful rings that can be dropped through a maze and watched roll out, demonstrating cause and effect.

The costume’s built-in fan can be powered by a power bank or the included battery pack; it requires 4 AA alkaline batteries (not included). For best performance use new alkaline cells and avoid rechargeable or nickel–cadmium batteries.

Rock-a-Stack toys support development of fine motor skills, gross motor skills, hand–eye coordination, basic problem-solving, and an early understanding of cause and effect.
