help with Seat Foam

[Hottrucks]

ok my bench seat is pretty good except for the driverside where my arse goes.... makes me lean on the door due to the lack of foam on the edge?? I could stay with the old school fix (pack it with news paper lol) but would rather see about changeing the foam and backer which looks like berlap??

any ideas or help would be great ...I don't want to change the seat but if it gets to expencive to repair/fix I'll end up doing that instead...I will say it will stay a bench..the other half likes to slide into the middle and lean over on me kinda like on a big date and it thats what it take to keep her in the truck then so be it....
