okay people will tell you to pull up and forward etc, it make take a little time and effort, but thats simply bullshit lol.
To get it out in two seconds, grab a crow-bar or a piece of strong metal at least 30cm, slide it under each corner below the seat and pull up. You'll hear it click, then just do the other side. It's easy for then on just pull it out and undo a few bolts.......i guarantee its the easiest way B)
