Needed-Upholstery work

[Baconator]

Hello. I live in Riverside county and am looking for someone to replace the bottom part of a seat in a 1993 Bronco. Took the seat out myself but can't figure out how to take the upholstery pad apart.

I've used Mike's Auto Tops & Upholstery but they are in Mission Viejo.
