What is the purpose of using quarter round for cabinets and how does it enhance the overall appearance and functionality of the cabinetry?

Quarter round is used for cabinets to provide a finished look by covering gaps between the cabinets and the wall. It enhances the appearance by creating a seamless transition and adds a decorative touch. Functionally, it helps to protect the edges of the cabinets and prevents dust and debris from accumulating in the gaps, making it easier to clean and maintain the cabinetry.
