IMPEX Force 4 seat foam

Hey all, just picked up an '07 Force 4 and and am going through a little refurb before getting it out on the water.

I pulled the seat and all the foam just all sorta fell off the seat.
I’d like to replace it with some closed cell as this is open cell and was still wet days after the test paddle.

Anyway, there was only one side piece and these two sections under the nose of the seat, no idea if there is supposed to be anything else.

If any other owners can post a couple of pics of their seat foam so I know if anything is missing, I’d greatly appreciate it!
