Cargo liner for when back seats are always down

I have a 2nd Gen 2010 that I'm 99% of the time gonna have the back seats down for the large cargo space. I'm looking for a cargo mat that fits the larger area with the back seats down. Can't seem to find any anywhere, all the liners I see have a lip that rides up the back of the back seats when they are up as well so when they are down it's just in the middle of the space.

I would like something that isn't too expensive but actually fits in and looks nice. If not maybe a combo of back seat back covers and a cargo mat without a lip or even a moving blanket but I feel that won't fit perfectly and will move around a bit.
