Planning from scratch: enter your tree distance and ridgeline length and get the strap height for a 30-degree hang
Hammocks & Lounging Museum
Wander an illustrated museum of the hanging bed and the hanging seat across cultures — hammocks and swings worldwide, the covered porches built for sitting still, the camping method of sleeping suspended off the forest floor, and the knotted-cord craft of the macramé hanger — each in its own wing, every image and fact drawn straight from Wikipedia.
