Query: Fits nicely, but HOLDS ODORS, it STINKS

This thing works good except that it holds odors and stinks all the time. You wash it and it smells OK. Your dog gets on it once or twice after a walk or a run in the park, and it will hold every odor forever. After a few days, it smells like your dog X10. So if you REALLY like the way your dog smells, you might be in heaven, but most folks will probably hate the odors that come from having this in your car on a hot summer day.
