I got a wild hair and decided to chop down my summit sp seat. In trying to lower it to look like a expert seat and slim it downing the sides towards the rear. I picked up a 20 gauge stapler and 1/4” staples (under $50) from Harbor freight . With a few cuts and staples it was done. I used landscape fabric glued on the top of the foam to give it a smoother feel under the factory stretched cover. Hoping it works out fine.
