Where to get new bucket seat foam?

[87 WE2]

Guy's I am looking into recovering my Gn seats front & back.
I have a lead on oringinal 87 1500 mile seat covers but I need to replace the drivers and passengers bucket seat foam because its shot.

Is new foam/cushions available anywhere? Thanks for any help

Most interior specialty shops have the proper foam that they can use to make new cushions or simply boltster your original foam cushions.
