What protection when back seats are down to carry larger loads

[Scifly]

Can anyone please recommend a boot cover that will protect back seats when they are down and also protect sides of boot plus bumper. I will be using back to carry a lot of fishing gear so it would be useful if the cover/protector could split if I was only putting one back seat down.
I have looked at a lot boot protectors but most are for dogs and do not have the split or fully protect the back seats and boot when seats are down.

I bought some from aliexpress.com
Do a search for mg hs car trunk mats
They split to allow for your seats folded down.
