It all went well. There are built in hooks in the seat bottom. There are clips on the seat back and a channel for the back side. I rubber hammer helped that cooperate. Getting the front seat bottom was the hardest part for me. It was tight. It took four man hands. There are a few wrinkles but some direct sun should help. I had the nasty white stuff on the back plastic. Steam helped get that off as well as Simple Green. These are well worth the money and they feel great.
