Derek is right. To keep an ultralight 3 legged stool stable you need to tie the bottoms of each leg together in some fashion. The top is obviously held together with the fabric seat. If not secured at the bottom, the legs will splay and it will fail at the mid shaft joint.
Allison- when there are no trees I pitch the hammock on the ground with the tarp and use it like an elaborate bivy. Admittedly it is not much of a seat in that conformation, but neither is any tent or bivy. I also use my Contrail or SMD Gatewood Cape if I know trees will be in short supply.
