the first thing to do on the top half of the seat is to remove some staples that are holding two plastic strips together





after the staples are removed the two plastic bits need to be seperated, they hold the front and back seat fabric together at the bottom of the top half of the seat and are a complete git to get apart there are three seperate clips on the front fabric clipping into a single clip on the rear fabric, I used a small screwdriver to make a start on each one then followed it along the length till it was totally unclipped this was the worst part of the whole job.
