Rear cargo mat with seats folded down

[Zachlc 0]

I’m trying to find a cargo mat for the rear of my 2017 Spark. I removed the bottom part of the rear seats so they fold almost flat. I’m looking for something that will cover the whole rear area with the seats folded down. Doesn’t have to be a perfect fit, but I want it to be close to the right size and shape. Anybody shopped for one of these before? All I’ve found via google is universal or cut to fit.

If it was my Spark, I would buy a non-slip rug slightly bigger than the area to be covered and cut it to exact size.
