Designed for children ages 2-12, Simple Bongos offers music to a playground at a fraction of the traditional investment. Children enjoy drumming to their own beat, and that is what we had in mind with the design. A playground needs to provide activities that induce involvement with motor skills and creativity as children will then unknowingly develop new abilities on the playground of all places. The four drums are mounted in-ground by a single center post. Simple Bongos come standard as portable. An in-ground anchoring kit is available for purchase.
