I've read this a couple of times and no one has told you the easy way of removing the rear seat squab.
After releasing the two front corner clips, if you lift up the front of the squab, all you're doing is pulling the bars you want to release from the hooks deeper into the hooks, making it almost impossible to get off.
So . . . release the front corner clips, keep the squab as flat as possible while still clearing the front clips, put your second hand beneath the backrest and grab the back edge of the squab. Push the squab back while lifting with the rear hand. It works rather easily.
When putting it back on, again, keep it flat, rest the bars on top of the hooks, push backwards and down with the rear hand. They soon slip under the hook.
Finally, pull the squab as far forward as it will go, to line up the front clips perfectly.
Job's a good un
