So far we've been just using an old comforter to cover the back seat of our F150. We don't have issues with 'accident' messes or such. Our issues from Ryder (male 7.5mo husky) are obviously the fur on the cloth seats and he likes to rest his head on the back of the seats to look out the back, which pulls the comforter off. However, the main issues we're dealing with are from Taylor (female 5yo shih zhu)... She tends to get down on the floor where we can't see her, which isn't good and prevents us from being able to use the floor space for other things (groceries, baggage if we're traveling, ext). She does get car sick sometimes, and when the comforter gets bunched up she'll either be sick on the seat or she'll 'bury' it in the comforter.

We would like something that is big enough to cover a truck back seat area, stays on and won't fall down when Ryder looks out the back, and also that keeps Taylor from ending up on the floor.

Any recommendations for covers/hammocks? Also would appreciate heads ups on covers you have tried but wouldn't recommend.  Thanks!
