Milk Street offers one convertible crib in the True Collection. This collection is rare; it defines “Rustic Contemporary.” Unlike most furniture classified as contemporary, the True works well with all styles. This high-back, convertible crib boasts an amazing contradiction of deeply sandblasted Spruce wood framing sleekly painted surfaces. Thick angular frames against simple spindles offer a contrast that we love. Our cribs are built to last through adolescence and beyond with iconic design and one-of-a-kind finishes. Bottom line: you won't find a better built crib anywhere. The True 4-in-1 convertible crib converts with ease from crib to toddler bed, to day bed, and finally into a gorgeous, adult full size bed with the purchase of our conversion kits (sold separately). This crib fits a standard size crib mattress (sold separately).
