I fit something like this (2pc futon with ottoman) from Costco during a snow storm in 2019 (snow was coming down hard with accumulation less than 6cm or 3in), so I didn't take photos.
Wife really wanted it that badly that night, and since it was snowing and Costco about to close soon, it was the perfect time to avoid the crowds.
The only thing that needed assembly were the legs, so it's quite bulky even with the box removed and the futon in upright L shaped form.
It's like a double bed if flat.
I had to adjust the driver's seat forward so that the hatch would close. It probably took the two of us 10min to nudge it in there because it was quite a snug fit, and I didn't want to scratch up a 2mo old vehicle.
