Felt is a material that protects furniture from the lamp base. We sell adhesive felt by the yard. Small felt dots can be used in place of a large surface and they are sold by the dot. Non-adhesive felt pads require glue to be set in place. For installation of adhesive felt: Trace the pattern of the base on the paper backing to the felt, cut it to size, peel the back and apply to the bottom of the base.
