This is my first time posting here, i hope i've selected the right section.
I recently got myself my dreamcar 480 2 months ago and i'm looking to freshen it up a bit

Couple weeks ago, one of my friends noticed there was some green stuff coming out of the headrest.

Sure enough it was foam that had fallen apart... And i've been searching online and on this forum if there are any DIY replacements you can
make for the foam? I'm thinking about getting a thick sheet of foam and just cutting out parts and stuffing it in, but idk if it will look any good...

Here is a picture -

Has anyone made anything similar?
Thanks in advance!
