It wasn't bad at all. Two things of particular note. On the positive side, the hammock was far far less "tippy" as I move around. On the negative side, the hammock isn't flat down by the knees and legs, and there's the same sort of hyper-extension as you can get with a gathered end hammock. I think that would be solved easily enough with a pillow or something under the knees. With the wide space up by the shoulders, and adequate space around the hips, this could be quite a viable way to sleep on your back. Not so good for the side or stomach though.
