I like these furniture protectors.  I had bought two in the spring, one for another sofa and one for a chair that the colors have faded from the sun. The protectors  work well and look nice.
  I needed another for the sofa our pet likes to relax on. They are comfortable and the colors blend well into the décor.
I would recommend these to preserve a new sofa or to hid any flaws on an old sofa!
They are inexpensive enough, that you can change the look frequently, if you desire!
