I don't have trees for a hammock and didn't want a metal frame so just an easy DIY project. 2, 4x4 posts. 8 ft tall each. 3' into the ground with cement. Then just 2 screw hooks and that's it! A hammock with spreader bars should be hung between 4-5 feet off the ground so mine is around 4 1/2. Tip: Rent or borrow an auger if you can, especially if you live somewhere with harder soil. The depth of the posts is key!
