Rainbow Play Systems has chosen choice cedar for the same reasons homeowners choose them for their decks and siding. It ranks the highest in dimensional-stability among commercially harvested woods, which means it splits less, warps less, twists less, and shrink less. It also hold paint better, and are virtually free of sticky pitch pockets and resins. With notched big beam, dual bold constructions, commercial grade swing hangers, and heavy-duty canopies, Rainbow® Play Systems are design for years of quality play.
