Brazilian reclining technique
The most important thing is to arrange the hammock's suspension loops at head height, and only some 3 m distant from each other, thereby allowing the hammock to hang down in a deep arc. This allows a diagonal lying position, like a real Brazilian ("from corner to corner"), and not straight. This keeps the back straight and is the secret of being able to lie comfortably and relaxed for hours in a hammock. As wobbly spreader bars are intentionally not used, one lies securely and without fear of falling out!
Even if you are only going to use your hammock for relaxation, you should still try to adopt the Brazilian way of lying: Contrary to European ideas, hammocks are not hung taut.
Lying crosswise has another benefit too: the side material of the hammock is stretched tight so there is no chance of it coming together above your face and obstructing your view.
