It is recommended to use felt pads or barrel-type coasters (do not use plastic coasters) under chair legs and other furniture. The felt pads come in various sizes. Some pads stick on the bottom of the legs and others need to be nailed on. Follow the directions provided with the pads. Check and clean the pads often to prevent debris, dirt, and small particles from being trapped in the pad, which may cause scratches in the floor’s finish
