This condensed play unit offers the basic experiences of climbing or crawling up and down and sliding. The deep entry platform has enough room to take a break, too. Crawling and sliding are fundamental to the young child’s development of motor skills. Apart from being stomach tickling fun, sliding trains the vestibular system. Climbing trains the young child’s cross-body coordination and thus proprioception, both important to the young child’s mastery of the physical skills that form a basis for both social skills and thinking skills.
