Bed caster is a type of caster wheel designed specifically for use on bed frames. They are typically made of durable materials such as metal or plastic and are attached to the bottom of the bed frame so that the bed can be easily moved or repositioned. Bedcasters are available in a variety of sizes and styles, including locking and non-locking versions.

They are typically sold in sets of four or sets of six and can be easily installed by the user. Bedcasters are a convenient and useful accessory for anyone who wants to move their bed around without having to lift or drag it.
