The rainbow arch trio features 3 semi-circle soft play pieces that fit into one another to form a rainbow arch. The beautiful set is constructed from leather and dense foam. It is easy to sanitize and wipe down. The colors were specifically chosen to stimulate young, active minds. It can be used at home, in daycares, or young childhood education centers. This set will encourage toddlers to reach their developmental milestones. Children will enjoy climbing over it, under it or taking it apart and putting it back together. They may use it in an obstacle course and can rock on it when turned upside down. Such movements improve core strength and stability. It provides a multisensory experience as it incorporates touch, movement, and visual perceptual integration. Climbers will build gross motor skills, balance, and motor coordination. The rocking movement provides vestibular input which can be calming and organizing for a child.
