Bumperless Baby Bedding is the safe alternative to bumpers. A must-have for a convertible crib are crib rail covers, also known as a crib wrap, to protect the wood against the effects of teething. Liz and Roo manufactures crib rail covers to coordinate with all our crib bedding. They serve a valuable function while adding a beautiful finishing touch to the crib bedding set. Crib rail covers are 18" when laying flat (9" folded). The American Pediatric Society recommends "bare is best" and our crib rail covers are a safe, secure way to not only protect the wood, but to finish the beautiful "look" of your unique baby bedding.
