Since most here are similar in the fact that we spend a lot of time in our living rooms listening to music or movies, I have a question for those of you who have hardwood floors. What do you guys suggest or have under your chairs, couches, or sectionals to prevent damage and sliding on this type of flooring? I have a sectional myself and it doesn't sit on legs, but on bars that run along the front back and sides. What do y'all suggest? Rugs perhaps?
