I don't have that problem either. DH uses his and I actually find myself cringing when he just leaves it piled on the couch, or lets the kids sit all over it. I don't say anything though, it's his quilt to do with as he pleases. It was made to be used, I just use things a little more lightly than he does. :)
I'd say you should pull his quilts out of the closet and put them on the couch. Tell him if they get ruined you'll make him a new one. Plenty more where they came from! :)
