Since AS kids do tend to have a need for a physical stim, it could be worth a try. But, you have to be sure that it would be satisfying to your son and that it really would replace trashing the furniture. We gave up and went the trashing the furniture route; just didn't have room for anything else, and didn't think anything else would work.
Something not too permanent is good, so that you don't have a huge issue if it needs to be changed again.
