I have and used a hennesy hammock. Love it. I have only used it for a 10 day trip. Always had trees to hang it from. I have read online that it could work on the ground, but never tried it. I normally sleep on my side or stomach at home, sleeping on my back was not an issue. I could even sleep on my side in the hammock. I did use a foam pad, for insulation and to keep mosquitos from biting me through the fabric. I liked that it was smaller and half the weight of my tent. It set up very fast. My only compaint was that there is no room for my panniers inside.
