It's cardboard with vinyl on top. Don't know if the vinyl attaches to the cardboard in any way or not, though. Mine was water damaged and everything was a mess with the vinyl flopping around and insulation flying everywhere if I had the windows down.
They are easy to find cause all the suppliers have them in the different colors. Around $20 to $25 last time I checked. It's just cardboard w/paint on it & a strip of vinyl to glue down once you pull the back seat.
