The Belden Collection is the perfect solution for shared or small spaces. The platform and bunk beds are made out of solid wood frames and feature extra storage. To finish off the collection, we use appliqué molding on drawer fronts and brushed Nickel drawer pulls. Plus, it’s GREENGUARD Gold Certified, which means it’s built to contribute to cleaner air for a healthy home. HOW IT IS CONSTRUCTED Expertly crafted from solid poplar wood and MDF (medium density fiberboard), an engineered wood that lends exceptional strength and ensures that the bed will endure over time. Slat-roll foundation on lower bunk. Crafted with mortise-and-tenon joinery for structural integrity. English dovetailed drawers open smoothly on waxed wood glides, and feature drawer stops for safety. Our finishes were developed exclusively for Pottery Barn Kids. Craftsmen carefully paint our soft White finish in layers for a smooth, opaque surface. All finishes are sealed with a final coat of lacquer for extra durability. GREENGUARD Gold Certified.
