I love my hammocks.
I have a proper camping one with mossi-net for nights out and a lounge in the garden job too.
Both have karabiners at either end and I use long tapes to tie around trees, wall anchors etc and then back to the biners. Using the tapes I can tension the hammocks as I want to have them flatter (my preference) or bendier. Check out DD hammocks for tips.
Where there are limited suspension points I have seen people using bipods at either end (two stout sticks tied together. The tapes can then be used to tension down to a ground anchor.
I always sleep so well in hammocks.
The downside for instead of a bed use is that, it is indeed, difficult to shag in a hammock. Although not impossible 😉
