I recently bought the JRB bridge. I find it lies perfectly flat. Of course as with anything there is a trade off. In this case I find there is a little constriction at the shoulders. But, the flat lay more than makes up for this. Also, I can lie on my side, not in a full fetal position but I can pull my knees up half way. All in all the best sleep I have had in a hammock yet IMHO.
