In our home, "stuff" takes a backseat to people on almost every occasion. Another post discusses not letting children jump on couches because it "wears the furniture out". I remember threads where people rejected co-sleeping because they didn't want to mess up their bedroom furniture. I actually know a person like this. She refuses to move her big wardrobe out of her bedroom so her kids mattress could fit on the floor. 
If my kids want to jump on the couch, bang their forks on the table (and dent the wood - oh no!), pull all the cusions off the furniture and make a big castle, ride their (no clumps of mud, please) bikes around the house when it's raining outside, or otherwise use our "stuff" in a child appropriate way, I let them do it.
I never imply that keeping stuff nice is more important than whatever it is my children want to do. I think teaching children to value stuff over experience is a very dangerous lesson.

Ive tried to show the kids that stuff we take care of well lasts longer, and if it is my stuff I think I have a right to ask that it be treated nicely (just as the kids do about their stuff of course).
Some people don't have an issue with their couch being jumped on. I have had a number of couches that kids could jump on. Mattresses as well.
