When your child is ready to move out of the crib, this cozy toddler bed is the perfect next step. Its high sides create a snug little nighttime nest, yet it’s easy for kids to crawl into and out of unassisted. HOW IT IS CONSTRUCTED Built from solid poplar wood, birch veneers, plywood and MDF (medium density fiberboard), an engineered wood that lends exceptional strength and ensures that the crib will endure over time. Our Simpy White Finish is hand-applied and sealed with an oil-based lacquer for moisture resistance. Slat-roll foundation is designed for use with or without a box spring (mattress and box spring are sold separately). GREENGUARD Gold Certified: Meets or exceeds stringent chemical emissions standards. Learn more. DETAILS THAT MATTER Uses a standard crib-size mattress (sold separately). The use of veneers results in high-quality furniture with flawless surfaces and consistent color tones. Hand finished in layers for exceptional richness and sealed with a protective, child-safe lacquer. KEY PRODUCT POINTS All Pottery Barn Kids juvenile products are tested at 3rd party CPSC accredited labs to meet or exceed all industry voluntarily and regulatory safety requirements.
