I think someone should make a fabric out of Kevlar fibers coated with Teflon for use in furniture.
For people with cats, the Kevlar fiber cores would give the fabric resistance to cat claws. The Teflon coating would prevent hairballs from sticking.
It would also be good for Mafia types. If they have to shoot someone sitting in a couch the Kevlar would prevent any bullets that went all the way through the body from ruining the fabric and the Teflon would make the blood clean up easy.
