Tree Frogs Swing sets are unmatched in value, from the best double wall scoop slides and the swing set market to top quality hardware and lumber. Tree Frogs swing sets are constructed with California redwood and western red cedar which come from certified mills that have sub stained-year-old forest management. Redwood and Cedar are both naturally resistant to insects and decay. These two quality was have similar cell structure which allows them to be dimensionally stable (meaning these types of woods are unlikely to warp or twist) and they hold finishes/stain and fasteners well. Tree Frogs wooden swing sets are packed with challenging features and fun play events which will give your children years of athletic conference building; creative play; and imaginative play. Tree Frogs swing sets are built to last with a solid lifetime warranty to back them up. Swingset Factory Depot is proud to offer this brand to the Midwest.
