I was recently diagnosed as being allergic to dust mites. My sofas are old and need replacing anyway so I'm researching options. I don't like how leather and vinyl sofas feel. I live in North Carolina and they are sticky when you sit on them in shorts or short skirts. Does anyone know of any other options? I was thinking that it might be possible for some of the Amish wooden couches that have removable cushions to have encasements like what I'm putting on my bed. Does anyone know of places that sell anything like that?
