Reply to comment by psimian in Help Me Find a Decent Futon/ Bedding for Sleeping on My Floor? by Unequivocalallity

Why do you need an exercise mat under the memory foam? Is it a back thing or is it better than just a memory foam thing on top of the floor?

The firmer foam gives you support so you don't bottom out on the eggshell or memory foam topper

Exactly what they said. An ideal mattress is something that has increasing density and support the deeper you sink. Inexpensive futons, of which I have owned several, completely compress almost as soon as you lie down on them and you spend the night grinding your bones against the floor. Sleeping on just a topper has similar problems (done that too).

For me the minimum seems to be about 2-4 inches of total foam in two different densities as described. For packing into a car it also means you can take the mattress apart and stuff the pieces wherever they'll fit, and it's way lighter than a futon.
