Carpet castors are designed for soft flooring where there is more friction.
Hard floor castors have a slight braking system so there is more resistance on solid flooring to avoid chairs gliding too far or too fast.
Please select the castors for the floor surface you will mostly be using the chair on.
Hard floor castors can be used on carpets but the chair may not move very easily and carpet castors can be used on hard floors but the chair will be more difficult to keep still.
Over time, some marking of the floor will happen no matter which castors you select but protective matting can be bought from many high street retailers.
Glides are fixed feet rather than castors or wheels.
