Cribs can convert into full-size beds with the purchase of full-size rails (sold separately). Pali bed rails are hook-on, which are much more secure and practical than bolt-on rails. The rails are universal, meaning that the same item can be used to convert almost all pali cribs. Please note that when converting the crib into a full-size bed you need to use under the mattress either a box spring or a bunky board. Universal Full Bed Rails include hook-on wood rails and slats to convert your crib to a beautiful full-size bed. Slots are provided on the headboard and footboard posts for this conversion. It’s as easy as removing the headboard and footboard, then attaching the rails and slats. Within minutes you have converted your precious crib into a full-size bed that can be used for years to come. The finish is non-toxic and like all of Pali, finishes have been regularly tested to ensure that it exceeds the required standards for lead.
