I was walking through Lowe's and happened to see some very good looking casters. Aha, I thought, just what I need to raise our coffee table to a more comfortable height. (Yes, we eat many meals on our coffee table while watching TV!) It took husband George and me only a few minutes to screw these brass casters onto the four legs of our coffee table. What a tremendous difference! Much greater convenience for pennies and very little time and effort.
