There are five bolts you'll need to undo all togather, and two of them go back in. Take off the lower cushion, then you will see the bolts holding the back cushion on. Remove those bolts, then the back cushion needs to be lifted up off of some hooks that hold it in place. There is also a covering there in the back, and that needs to be attached to the back of the cushion. I've heard that spray-on glue works for that. Once that's done, hang the back cushion back in place, but don't bolt it in. Then put the bottom cushion back, and bolt it into place. Now when you want to put something through the back seat, just lift up the back cushion and lay it on the bottom cushion, and you are all set. And since it's held in place with those hook things, it will stay in place when it is up. Bear in mind, I haven't done this yet, but do plan on it in the future. But right now, my speaker box is kinda held in place by the back cushion, so it needs to stay in place. Hope this helps!
