The easiest way to move furniture is by gliding it across your floor. In the process of sliding and pushing, you also destroy your floor. The Container Store
has these sliders called Mighty Mover Furniture Sliders that you place underneath the legs of your furniture so you can slide it across your home without damaging your floor (that's what the description says anyway). You could technically also just place a towel under the legs and go about your business that way, but the foam cushion conforms to the leg and the plastic should make it easier to glide.
At $6.99 for a pack of four 2 1/4 diameter Mighty Mover Furniture Sliders, they don't exactly break the bank.
