A shelving unit is a piece of furniture designed to hold and organize items. It typically consists of horizontal shelves supported by vertical frames. Shelving units can be made from various materials, including wood, metal, or plastic, and come in different sizes and styles to fit various spaces and needs. These units are commonly used in homes, offices, and stores to display books, decorative items, or products. They help maximize vertical space and keep areas tidy. Some shelving units are adjustable, allowing users to customize the height of the shelves to accommodate different items, such as books or storage boxes.
