Just a few weeks before we adopted the boys, we got a new livingroom set. We were pleased and pleasantly surprised to see that the boys did rip up our couch, chair, or ottoman and that the microfiber fabric was strong enough to resist their climbing. That's a good thing, but it turns out that the boys have found a whole other universe of furniture to destroy.
They enjoy ripping labels or cloth or loose threads off the bottom of dining room chairs and desk chairs and then they try to chew them. It's looking more and more like we will have to replace our diningroom set and at least one desk chair. We have a collection of half broken chairs in the bedroom. They're usable for humans, but dangerous because the boys would end up eating and swallowing parts of them if they were out in the livingroom.
