Slide the center support beam into the spreader brackets, one bracket at each end. The center support beam and the brackets should be able to stand on their own, with two legs down and a single leg facing up.
Slide another 8-foot beam into each leg on the brackets that are facing upwards, forming the hammock supports.
Slide the four shorter leg beams into the two bracket legs, completing the base of the hammock stand.
Screw two self-tapping screws into the spreader brackets, through each beam.
