I bought similar seat covers but the quality just isn't that good. They are really thin and they attach to the headrest because they have two holes (one in each corner at the top) and a carabiner to connect them together. They're not $30 a piece, but maybe $15. I bought a much better one for 20€. I also have a feeling they only last a few washes. I love the design but this is the cheapest of all the cheap beach towels you can use.
