While many people think laying in a hammock means being bent like a banana, a proper camping hammock is meant for you to lay on the diagonal which can provide a very flat lay. A bridge hammock will get you even flatter. Done right it is much easier on the back than sleeping on the ground (shudder). Anyone with an interest can learn all they need to know over at Hammock Forums where it is said "don't hang higher than you're willing to fall". Exactly the reason I stayed clipped in for this afternoon break.
