Great website, thanks for sharing the DIY tips! I'm going to wait for haasman to do his swap and learn from his experience before swapping the seat bottom that my wife usually sits in!
BTW, for the 190E owners who have saggy cargo netting on the back of the seats, go to a dry goods store and buy a pair of plastic dritz brand cord toggles. Install them right in the midde of the top string and you'll be able to tighten and loosen the netting without having to replace the elastic.
