What is the optimal thickness for a mattress in a teardrop trailer? Please share what kind of bed you use in your teardrop trailer and how thick it is. It'd help to plan (1) how much room to leave between the floor and a storage cabinet above your feet and (2) how high the bottom of the door should begin above the floor.

Is it correct, as a rule of thumb, that the door bottom should be about half as high above the floor as the thickness of the mattress (so you won't cut off the circulation in your legs getting in or out?

BTW, I'm thinking of using a queen sized foam mattress between 4 and 6 inches thick because I'm 6' 4" tall and weight about 250 lbs. Maybe one from Ikea because they have a good selection. I'm beginning the framing of the side walls so it's time to make a decision for the height of the door bottom above the floor.
