Furniture casters are small wheels or rollers that are attached to the legs or base of furniture such as chairs, tables, cabinets, and desks. These casters allow the furniture to be easily moved and provide additional mobility and stability.

There are different types of casters that vary in size, shape, and material to suit different furniture styles and flooring types. Some casters may be locked in place to prevent movement, while others may swivel and rotate for easy maneuverability.
