DIY : Cargo Mat with an easy access to both the load floor compartments.
Material : Inexpensive
Rubber Mat (Made it invaluable with all work done

) and left over door edge protector strips.
Time : 2.5 hours
I got tired of waiting for a good quality cargo tray, which has access to the bottom storage bins.
So ordered a regular rubber mat and cut it to work as I want it to be.
Since the mat I ordered was a universal one, I had to do a good amount of planning and trimming to get full coverage.
Once I was sure it will work, I dressed up the edges with a bit of lip/thickness using some left over door edge protector strips.
The front mat stays in place even after opening, because I tucked in the back edge into the tiny gap between OEM load floor.
The rear one rolls out with the three stage opening of load floor. I might add some Velcro later.
I have left almost an inch of overlap between the two mats, so that either one can be kept below the other.
That is to make sure no dust/sand falls into the OEM load floor.
Since the edges are only having a small lip, water spill can still get there.
As expected, not happy that the mats themselves are just OK quality.
It will need some curing in the sun to get the wrinkles out.
Even after washing it, there is definitely rubber smell.
The mats are thin (can get torn with anything sharp) and lightweight.
Happy that It works as intended and now I can regularly access both the compartments with the mat on. They fall back into place when I close the lids.
