Does the batting material between the bottom layers matter?

We do flip the mattress every couple months, so there isn't really a definitive "bottom".

Well we just made it ourselves sort of on a whim, so I can't tell you one way or the other. It's just how we did it.

With 5 blankets and batting in between, how stiff is the mattress? Can you roll it up or is it pretty inflexible?

I've never tried to actually roll it, but you can fold it in half pretty easily. Folding it half again would probably be doable, but I think that's about as small as you would get it. Rolling it might work better, but I've never had a reason to I guess.
