I am needing to buy a rear seat cover for my 2018 XC60, I see that Volvo didn't make them beyond the 2017 model year. I want to buy a good one that stays in place. I see that Weathertech has one for about $130 that doesn't allow for use of the middle seat belt which probably isn't an issue for us. Chewy has quite a few for various prices.too. Any recommendations? For a 50 pound leggy dog if that makes a difference!
