Review on NAC&ZAC Deluxe Waterproof Bucket Pet Seat Cover: Complete Protection for Cars and SUVs, Quilted, Nonslip, Machine Washable - Seat Anchors Included! by Nichole Morris

I have a rear seat version for my dog that works very well (although the Velcro makes access to the seat belt holster difficult). This front seat version moves A LOT when people get in the car and a little when they get out. This was very annoying as when the dog sat in the front the dirt and sand would just slide off the cover and get under the seat, defeating the purpose. I bought tarp clips (from Revain) and after attaching one to each corner of the seat, I tied four under the seat to secure it. now i love it I took off a star because it didn't work out of the box. The quality is so good that I decided to leave and tinker with it to make it work. I have a Prius with cloth seats. Hope that helps.
