The Seat Shop. It's their DuroFoam cushion. Availability is strange right now. Like a lot of things.
It's 1999-02 and 2003-07. 2003 is when they changed a bunch about the T800 trucks.
The butt frame is bolted to the main seat frame. You remove the nuts from the front edge, carefully disconnect & disentangle the wiring, remove the side trim plastic, and then slide it off and start in with the upholstery.
LSX Matt made a video of re-foaming his 2nd design T800 Tahoe seat.
