Older dogs that start to chew can be from boredom, texture, or in your case something new and interesting. I would have to disagree that your dog knew that chewing on the bed was bad. Rather I would guess the body language, tension, frustration, anger, and awe had more to do with it!
A houseful of toys is never as fun as a person who will play with her and those toys. Redirect her and when you can not supervise her she goes into the crate or tether her to you. This is only temporary until she is retrained.
Sorry if I rambled.
