Colorado, The swing was simple to build. Any round limb, maybe 3" in dia. about 24" long. Four decent sized eye hooks and chain, cable or rope. Pre-drilled holes in limb and screwed in the eye hooks. cut two even lenghts of chain. Installed two more eye hooks in framework of run and hung the swing. Put first one pretty high off the ground, its at about 4'. second one I built I lowered it and it's at about 2 1/2' oof the ground. My four girls that swing like both heights. But 2 in perticular like the high on best and are on it every morning and again every evening before they go in for the night. It's so funny to watch them move their little heads back and forth to make the swing move. Hope it works for you.
