To be perfectly honest I'm not a big fan of hammocks in general. I don't know if it's my clumsy/uncoordinated nature, but I just find there's not enough support which makes it difficult to get into a comfortable position. I prefer sleeping straight, no pillow or anything, and hammocks are super curved, so it just doesn't work with me. Plus I'm always paranoid about falling out of them, but that's probably because I've watched too many Simpsons episodes.
All that being said, I'm enamored with the IDEA of the hammock and always want one of my own.
