I had my "porfessionally" installed and the boltsters are a little baggy, but the back is perfectly tight. He had two people work on them together. I think that one person streched them tight and the other person hog ringed it together. He was saying how leather shirnks over time, so things should be tighter as they sit.
The uphosltery guy was impressed by the quality of the leather. He said is was a really thick good hide. He couldn't even hog ring many of the panels. He had to punch a hole first in many of them.
