Respectfully, I'd consider another option. Felt gets flimsy. I'm SO happy with the Thule Go Box Large because it LITERALLY never slides and manages the Corsair’s weight distribution perfectly.

For your situation, I totally feel u. I've been driving my Corsair for about a year now and that sliding sound honestly used to drive me crazy too. It's such a quiet cabin that every little shift sounds like a disaster back there lol. It REALY ruins the luxury vibe when your groceries are playing bumper cars.

Since u wanna keep that premium feel and avoid the cheap plastic vibe, I highkey recommend a two-part setup. First, to stop stuff from sliding on your reversible mat, check out the WeatherTech CargoTech Cargo Containment System. It’s basically these four grippy L-shaped blocks that "stick" to the floor to wall off your gear. They’re super solid and dont look tacky at all. They work surprisingly well on the carpeted side of the mat too.

But for groceries and pickleball gear, I’ve found that the Fortem Car Trunk Organizer is a life saver. It’s collapsible, has a lid to keep things tidy, and it has these little straps that hook into the Corsair’s cargo tie-down points. I mean, it’s not felt, but the fabric is really sturdy. Just a heads up tho—be careful not to overstuff it so it doesn't shift and block the foot-activated liftgate sensor path if you’re using the "kick" feature. I've noticed if things hang too far over the edge of the cargo floor, the sensor can get a bit wonky, so definitely keep it centered.

If u really want that felt look, Rola 59001 M.O.V.E. Rigid-Base Trunk Organizer is another decent option that's pretty rugged but looks more high-end than a bin. GL!

I definitely agree with zxsnykdfvi about the risk of spills. You might want to be careful about where you place heavier items because if something shifts and hits the liftgate latch, it can cause sensor errors that are a total pain to reset. Methodical packing is really the only way to ensure the long-term reliability of those rear electronics. Last month I had a similar issue, not with groceries, but with a leaky bottle of car wax I left in the side pocket. Spent three hours scrubbing the carpet and now I am paranoid about every single bottle I carry. Looking into those specialized leather ceramic coatings just to protect the seats from my kids sports gear has become my new hobby. It is a never-ending cycle once you start worrying about the interior stayin pristine. Anyway, just make sure whatever setup you choose doesnt put pressure on the side panels.

Late to the party but I totally get the struggle. Honestly, over the years I've tried many different setups, and I actually had a gallon of milk burst in the back of my old SUV because it slid right into the latch... what a TOTAL mess. Since then, I'm super cautious about cargo management.

For the Corsair, you really wanna avoid those flimsy plastic bins. They look out of place in a luxury interior and they literally slide like they're on ice. In my experience, you need something with a weighted bottom or aggressive grip strips that wont damage the carpet but still hold firm.

Here is what I recommend for a budget-friendly but premium feel:

* Starling's Car Trunk Organizer 3-Compartment Collapsible - This one is great because it has reinforced walls so it doesnt sag. It stays put on the factory carpet really well, i think, and the material feels much higher quality than the generic stuff.
* Knodel Car Trunk Organizer with Lid - I highkey like this one because the lid hides all your gear, which keeps the cabin looking clean. It's sturdy enough that it doesnt tip over during sharp turns.

Basically, the lesson I learned is that 'modular' is key for the Corsair since the cargo floor length changes when you slide those rear seats forward. Just make sure whatever you get has a non-slip bottom so it doesnt fly around. Also, just a heads up—dont pack it so high that it blocks your visibility or the liftgate sensors. Safety first, right?? Good luck with the organization! 👍
