I'm confused by the original question... are we referring to the fact that the seat bottom flips up forward and the seat back folds flush (or close enough) forward once the headrest is removed or do you mean having the seat back fold backwards laying flat on the cargo area?
Perhaps you don't like the fact that the latching edge of the seat bottom sticks up and takes up a precious 10 inches or so from the top of the folded seat back to the back of the front seat.
Could it be that you are folding the seat back forward before foldsing the seat bottom up out of the way? If this is the case, there's a little strap tucked in between the seat bottom and the seat back that you can probably find buy digging around like you were looking for a quarter. It's in the middle of each seat. Pull it up and it releases the seat bottom and gives you access to another nifty little storage area for crap that you don't want flopping around in the back seat (like the tool set, a roll of duct tape, some bailing wire, rope, .45, emergency poncho, small gerbil, pictures of scooters, pez, cheddar goldfish, beer tabs, mice, spare hitch pin, gold bullion, gum, ping pong ball, or a dead goldfish).
