Peter,
do a little reading before the snap judgement on Clark Jungle hammocks, this isn't a typical hammock,
the clark hammocks are made so you can sleep on your side, I do it often and it is incredible. I am sure if you set up the hammock incorrectly it will be uncomfortable. If you are above the tree line you just set up the hammock like a tent. You will never sleep better in a tent then you will in a Clark Jungle Hammock, period.
Just read the user reviews.
