Cup holders are small, often circular, compartments designed to securely hold beverages like cups, bottles, or cans. They are commonly found in vehicles, such as cars and trucks, as well as in furniture like sofas and chairs. The primary purpose of a cup holder is to prevent spills and provide easy access to drinks while on the move. In addition to vehicles and furniture, cup holders can also be found in public spaces like movie theaters and stadiums. They come in various designs and materials, including plastic and metal, and can be adjustable or fixed in place. Some cup holders even feature additional functions, such as cooling or heating capabilities.
