I don’t agree with the hippy sentiment on display here, but If you have a lot of junk in your safe, and not much in the way of furniture, there’s a British artist out there that might have some ideas to help you out.
 
This one chair looks like it uses Kalashnikov receivers that are pretty much intact. Believe it or not, I think importation of some of that furniture into the USA would be a violation of ATF regulations concerning importation of machine guns, as a receiver that was once part of a machine gun is regulated as such. I believe the ATF requires machine gun receivers to be cut into several pieces in order to be considered demiled.
