Designed for children ages 5-12, The NatureROCKS set of tree stumps for school aged children includes a trio of steppers with varying sizes that range from 12 to 28 inches in height. Children will enjoy challenging themselves by trying to balance on top of them, or crossing them by jumping from one to the next. The height differences of the stumps makes for a more difficult challenge better suited for children aged five and up. These stumps also make great places for kids to simply sit and talk to each other, which is an important and often overlooked aspect of playtime. They are almost indistinguishable from actual wooden tree stumps, but are made from incredibly sturdy and detailed glass fiber reinforced concrete. Their durable materials ensure that they will retain their sculptural appearance, rugged bark texture and hand painted finish even after years of outdoor use. They can be arranged however you choose, and make great accents alongside other rustic decorative structures.
