I am usually a side sleeper and, ultimately, was kindof a modified and de sleeper in the hammock.  When I finally got diagonal (I had some trouble fining where to put my head and legs to "get diagonal", if that makes sense), I seemed to naturally can't toward the side of the hammock that my head was on.  I also tend to wiggle around a good bit though and kept losing my sweet spot.  It wasn't as comfortable asy bed at home, but I think it was more comfortable than the ground usually is.
