When looking for casters, you can find a variety of options from companies that specialize in industrial and warehouse equipment. Most of these companies sell products that are ideal for manual transportation. The Model 9 industrial caster is the most popular choice, and it has a relatively low initial price. When selecting a caster, keep in mind that its capacity rating is based on ideal conditions and does not take into account how much effort it takes to move the load. It also relies on the rollability of the wheel, which depends on the environment and floor surface.

When purchasing your casters, it is important to know how to attach them to the legs of your furniture. When attaching casters with screws, drill holes in the wood to match the size of the screws. You should also make sure that the hole is large enough to fit the stem sleeve, which comes with the casters. This link
