In thailand most of the places I stayed had really thin futon type mattress's or even thinner like a mat or a rug even,it took a few days to get used to but after a couple days I slept the best I have slept in my life. I would have to say thou the best bed I have ever had was sleeping in my tent on the beach,the sand molds to your body(giving space for things like your butt haha)...............if only they made beds of sand!
