Overall: This isn't my first experience with these seat covers, but I found them quite a hassle to install. See if I take the time to go to your website for more installation instructions, anything longer than a 60 second video would be very helpful. You haven't explained all the panels and how they are used to set up your 6040 and seat in general. For my 2016 RAV4 I used the smallest size for 40 and removed one panel from the remaining for 60 for both the seat and backrest. Took me about half an hour to put them on. Straps: The way they are cut makes them difficult to thread, especially due to the awkward angle. They're not all straight, and some of them are frayed. You can cut off fresh ends. Also, I'm not entirely sure about the durability of the harness connection points, especially where they connect to the front edge of the seat (see image, here it's attached to a fairly thin mesh). Volume at the hinge point of top and bottom, demonstrating its universality. The front seat covers (another brand) are very comfortable and I am regularly asked if they are custom made. The whole situation with accessing the seat belt buckle is pretty weird. I have them just below the zippers so you have to open the covers to get to the buckles. However, the zippers are very smooth-running and want to open completely due to the pressure on them as soon as they open. Once partially unzipped it's almost impossible to fully zip up as the excess will be tightened and tucked away, so hopefully they won't unzip themselves over time. Also, each of my headrest covers were missing one of the drawstrings (all on the back/mesh side) so they don't fit very well. The headrest covers are too big for my headrests but I think mine are too small. Now that I have them on my seats, I don't plan on taking them off until they fall apart. I think they'll do a great job, they just won't look 10/10 while they're at it.
