A "swivel" refers to a pivoting or rotating mechanism that allows an object to turn around a central point. This movement is commonly found in furniture, such as office chairs and bar stools, enabling users to easily change direction without needing to move the entire piece. Swivels are also used in various tools and equipment, including fishing tackle and camera mounts, where flexibility and ease of movement are essential. The design typically involves a bearing or joint that facilitates smooth rotation, making it a practical feature in many everyday items.
