Easy to assemble. Although it's not very easy to make the arbor 90 degree on both side. I also notice 2 of the arbor posts I received are slightly curved. Since this is a very cheap arbor. I accept the mild defect. There's something the picture didn't show and nothing mentioned in description is that the 2 arbor top don't have end cap. There are huge holes exposed up there. They don't look very nice if you look at it from the side.
