vito 111cdi 10 plate - underseat storage???

just purchased a vito 111cdi on a 10 plate, and this MAY seem like a stupid question, and obvious to some.....but how the hell do I get into the underseat storage areas? have a bench seat for the two passenger seats, and a standrd driver seats, situated on a black steel raised box, that apparently has nothing inside it. IS this supposed to be underseat storage...if so how the HELL do i get into it...i.e. do the seat pads flip open or something?
