Typically, office chair casters are made from rubber or plastic and are attached to the bottom of the chair's legs. As a result of the caster wheels, the chair moves easily and can be controlled more easily. There are different types of casters for different types of floors. While some can be used on laminate flooring, others should not be used anywhere. It doesn't matter if the caster is designed for laminate floors. It will still scratch and damage the surface. Casters are abrasive when they move across a surface.
