When I say the floor is comfier I mean it, no mattress or anything, and at most I use the support of a pillow or two. I live in an area where it's consistently hot, where it really only drops below room temperature in the winter, so for a good majority of the year so falling asleep is difficult. The hot weather makes couches and blankets pick up heat too easily. Even if I lived in a cooler area I would still detest beds and couches since I tend to find soft surfaces to be rather unpleasant. On the other hand, the floor, which usually carpet, usually has a hard surface with a consistent temperature that makes it enjoyable to rest on. I like hard wood floors too since the cold feeling is nice I find to be pretty refreshing, but not in a thirsty kind of way if that makes sense.
