This vinyl is only 2 way stretch and isn't as workable as the 4 way stretch I've used before. It took a lot of heat to form the center seat sections. I found that removing a small piece of vinyl from the middle of the seat area first, made it easier to stretch, and saved many staples. Be careful not to removed too big of a piece. As you can see in the pic, the piece I removed became a much larger void after stretching. If I had removed any more, it would have been tough to get the first row of staples started.
