Chair trauma

Have teeth will tear up. That is what the ad should have read for this puppy. I have never seen a dog crawl underneath a chair and tear a chair up. I have seen dogs tear up cushions on a chair or pillows on a chair, but never under the chair. Spraying bitter spray on the underside did not seem to affect her. She first started with the tearing of the lining. Then she chew through the plastic like barrier that was between the first layer and the springs. LAst night she hit cushion that was somewhere on the chair, because when I flipped it upside down this morning there were no tears in the fabric. I think they put padding on the side. So what do I do? I have yelled, pulled, substituted, timed out and crated her. Last night she got an earlier bed time. SHe was not happy, but this morning she was right back to the chair. I was told 3 minutes/ time out so they remember. But I was too tired last night to let her back out. She did get a bathroom break and it was only 1/2 hour before she naturaly falls asleep, so I was not a demon. But seriously, How do you stop this crazy thing?
