I have new oak floors. We want to get some wool area rug. But we were wondering whether the rugs will protect or damage the floors. Also, those of you who have area rugs over your hardwood floors, do you pick them up to clean under them? How often? Area rugs are usually installed over protective padding- Amazon.com - Grip-It Ultra Stop Non-Slip Rug Pad for Rugs on Hard Surface Floors, 8 by 10-Feet - . not only will this protect the hardwood but it also keeps the area rug from slip sliding away.
