A caster is a device or component used for attaching to the bottom of furniture, appliances, or other objects to enable easy movement, primarily across the floor. These small wheels are typically attached to a swivel mechanism and are often made of rubber or plastic to provide smooth rolling. Casters are commonly found on chairs, tables, carts, and various forms of equipment in both domestic and industrial settings.
Due to their versatility and convenience, casters contribute to the efficient transport and mobility of objects. They are designed to swivel in multiple directions, allowing for easy turning and maneuverability. Some casters may include brakes or locks to keep objects stable and secure in a particular position. They come in various sizes, load capacities, and materials, enabling suitable options for different applications.
In addition to their functional aspect, casters can also have aesthetic purposes, as they are available in different styles, colors, and designs to match or complement the appearance of the object they are attached to.
Overall, casters play a pivotal role in enhancing mobility, convenience, and functionality in various environments. Whether it is moving furniture across rooms, transporting heavy objects in warehouses, or providing ease of use in healthcare facilities, casters prove to be valuable tools in minimizing effort and maximizing efficiency.

The word "caster" originates from the Late Latin term "castellum", meaning "a fortified place" or "a castle". In Old English, it evolved into "ceaster", denoting "a walled or fortified town". Over time, the word "caster" emerged as a shortened form, specifically referring to the device known as a "caster wheel". This wheel allows easy movement by rotating on an axis and is often attached to furniture or other objects.
