The set consists of 4 metal parts that look very stable, and two ropes, which also act as if they could properly what endure. Although the only "read" guidance is a picture on the back of the pack, I had the mat hanging as completely inexperienced Erstaufhänger within 10 minutes. Super! None of the items is really big or heavy, therefore that is my opinion and easy to transport. Contrary to the illustrated, I think it makes more sense to wrap the rope twice around the tree before you do it firmly. For the cable length is sufficient even with our thick, ancient walnut tree.
