Having backpacked all over Japan for a couple of months (had a great 
time!) I slept a lot on Futon mattresses, and slept really well!

Now I want to exchange my bed for a Futon on the bedroom floor here at 
home, and be able to use that space the bed would usually take up as 
well, by putting the mattress away during the day.

I have friends in Japan who could send me a mattress, but what kind of 
mattresses are there, and which one should I choose?


I've checked around here (in Norway), and I did find a store selling 
Futons, but at a price! And I was told that I need to put something 
underneath and not just place them on the floor. Obviously these aren't 
the original types of Futons as used in Japan, but I'm a little confused 
now.... so if someone would care to enlighten me about the subject so 
I'll know a little more about what to ask my Japanese friends to send me.

Thanks
