I was able to install them myself. They appear to be of good quality. I'm not a fan of the hooks they offer for attaching seat covers. I would have liked a slightly larger S-hook. One of the straps was poorly sewn to the seat cover and broke under slight tension. Update A few more straps came loose from the seat cover so I bought small S hooks and replaced them with small elastic cords. They keep the cases in place and no more problems. One reviewer said the seatback covers were too small. They are very tight and I had to inflate them a lot, but they fit great.
