I didn't do the work all at once, I split it up into a couple days because I had other things to do. I could've been done in less than 2 days had I had enough time. As for difficulty, taking the seats and seat covers off were no problem, but getting the hog rings in place and hooking the new covers on was pretty hard, even with hogring pliars. I think I did it pretty well considering this is the first time I've ever done anything like this. I don't know how professionals are able to do them in only a few hours!
