Could you possibly post a quick sequence to get the seat cushion out to start the process of replacing cushion/mat?

I'm just about to do this on my sport seat. Bought used seat bottom off eBay for $100.

Looking for something like:
Disconnect battery
Remove seat back panel
Remove belt
Remove headrest?
Remove bolts
Remove seat

Probably more detail than that. I'm quite capable just need the sequence of events.
