The term CRIB PARTS can be broken down into two crossword solutions: SLATS (5 letters) and SIDES (5 letters). SLATS are thin, narrow strips of wood or metal that form the base of a crib. They are usually arranged in a grid pattern and provide support for the mattress. Sides are the vertical panels that make up the sides of the crib. They are typically made of wood or metal and are designed to keep the baby safe inside the crib.
