It really IS EASY.
It sure makes the job ALOT easier.
it's only 4 - 5/16'' nuts to undo the seat frame from the sliders, after you pull the back and bottom seat cushions out. The back has 3 screws @ the top tabs and the bottom simply lifts out, undo the 3 screws, pull top forward and lift out. Pull the front of the bottom cushion UP, then lift forward. The seat was designed to be lifted out SO you have storage under, it is not necessary to remove to back before the bottom.
WOW, look how much room there is under the cushion.
think about cutting (sawzall, in two sections) the front skirt panel so you could use that area for storage.
