From increased mobility to purely an aesthetic choice; picking the right caster for your table leg matters. Choosing to use a caster is only the first step, there are many factors that go into choosing the right caster for your furniture. The first, basic decision in choosing the right caster is deciding between stem mounted and plate mounted. Stem mounted casters work specifically with table legs and other furniture pieces that accept the stem. These are easier to install if they match up properly. Plate mounted casters can be bolted or welded underneath any type of furniture. They also offer a more stable mounting base than a stem caster.
