How you hang your hammock depends on what kind of anchor points you're using. If you plan to hang it between a couple of trees or posts, you'll need to purchase tree hanging straps separately. A pair usually costs about $10 and will make anchoring your hammock a breeze.However, if you want to anchor your hammock to two walls, installation is a bit more tricky. You'll need to get steel wall-mounts, and you may need a masonry drill to attach them to the wall. If you're not sure what to do, it might be best to get a professional to fit the wall-mounts. Or, you could use a hammock stand instead.
