A friend asked me a while ago if I used those little paper toilet seat covers or if there were some ecological alternative that I knew about.
Depending on the restroom, I'll either use the paper seat cover, hover or go bareback. But it got me thinking, was there an industry for take-along handsewn fleece toilet seat covers made by SAHMs? I know you can buy disposable covers for your kids, so I went on a search.
I didn't find any for adults, but I did stumble across this complete waste of plastic: toilet tattoos. They are actually kind of cool, but what a useless product.
Anyway, in my search I also came across an article discussing the merits of even using the paper covers. They state that the seat covers really only mentally separate your backside from those that have visited before you and that you have more to fear from the door handles and faucets than from the toilet seat.
In spite of the vinyl products geared towards kids, I can't really find any suitable environmentally friendly alternative that isn't a pain in the ass to carry around and use. So, I can only suggest that you skip the paper seat covers and save some resources. If the seat is too disgusting, then work on your quadriceps muscles and hover.
Here's a tip for those of you who hover and have terrible aim... lift the seat up (you won't be needing it anyway), do your business and put it back down. That way you won't leave a damp seat for the next person who may choose to ride it bareback.
