Comfortable
Very comfortable, even as a side sleeper. It doesn’t seem to line up exactly with the bump out, but that’s not a big deal. I wish it was easier to roll up tighter for storage, or came with a storage bag, but I imagine it must be difficult to put in a storage bag. If rolled tight enough I can store it in the back under the floor since I don’t have a spare tire. Overall comfortable, but pricey and bulky.

Shockingly comfortable! I recommend leveling your trunk with some risers. Fit is pretty good in the car, not perfect.

Glamping In Style & Comfort
In combination with the Rivian in camping mode, two of these mattresses in the back made my last trip the most comfortable camping I have ever done. They fit very well in the Frunk, although it gets quite hot in there. So I wouldn't recommend storing them in there.
