So I recently went on a camping trip and I bought a $100 Amazon twin foam mattress. I sort of got around the whole fit under the trunk issue by putting a cooler in the trunk and then the mattress in the actual trunk.

I think you need to advertise the compression of it and how much less space it takes up compared to the amazon one below. My mattress eats up a good 3/4 of the trunk with the seats up.

That being said, I didn’t have to piece the Amazon one together and I could leave it in its protective plastic and not be worried about dirt with no noise issues.
