The Natart Linea Island Convertible Crib showcases Scandinavian design in natural oak wood with a refined finish that lets the exposed grain shine. The island crib converts to a toddler bed, daybed, and 54-inch double bed, with a wooden mattress support offering three adjustable heights and hidden hardware. Made in Canada and GREENGUARD Gold certified with non-toxic, very low VOC finishes, it is anti-entanglement tested with no protruding parts and meets all US and Canadian safety standards. All beds use a 54-inch mattress with a box spring or bunky board.
