Totally crooked! My husband is incredibly handy. No matter what adjustments he made in tightening/loosening the hardware, it would NOT sit on the level floor without wobbling. Lucky for us, it is sitting on a stone hearth which isn't perfectly flat (since the stones have natural variations), and it sits on that perfectly.
Furthermore, I was going to try to surprise my husband by putting it together in advance. I'm not incredibly handy, but I can certainly follow directions. The directions are terrible providing no insight on where the washer should go. The tools provided made it almost impossible to tighten. Fortunately my husband has a ratchet and screwdriver which he used with much greater ease.
