Buyer beware! The posts and crossbeam are NOT made from solid 4x4 timbers, as the description leads you to believe. Rather, they achieve an overall dimension of 4x4 by gluing pieces of 2x4 lumber together. Mine split in two places along the glued joints during the assembly process. Guess I'll mix some epoxy. To add insult to injury, several of the holes and fittings were improperly drilled/placed, so the only way to get this monstrosity to go together will be to redrill these holes and reset the fittings (which I'm sure would void the warranty). Guess I may as well go ahead and try though, since the item is NOT RETURNABLE! So now I find myself stuck with nearly a $1,000 piece of junk that was meant to be a birthday present for my father. Happy birthday, Dad...At least it looks pretty.
