A tray is a flat, shallow container used for carrying or holding items. It often has raised edges to prevent objects from sliding off and can be made from various materials, including wood, plastic, or metal. Trays are commonly used in households, restaurants, and cafes to serve food and drinks. Trays come in different sizes and designs, catering to various purposes. For example, a serving tray is larger and used for carrying multiple items, while a breakfast tray is smaller and often used for serving meals in bed. They can also be decorative, enhancing the presentation of items placed on them.
