There's something to be said for effortless beauty, and the Riley 4-in-1 Convertible Crib has it in spades. It's the ideal selection for your baby's classic room, with defined curves and smooth slats that provide an understated elegance. This crib can elegantly convert into a toddler bed and day bed with the purchase of the toddler guardrail. To convert into a full-size bed requires the purchase of a standard Hollywood metal frame. We recommend using a bunkie board or box spring under the mattress for conversion. (Conversion Kits sold seperately).
