The structure is great. Very sturdy and was easy to assemble. However, as I am now reading on other reviews, the Vulcan Black is truly navy blue. We have monochrome decor and this thing sticks out like a sore thumb. 
I like the style so I'm going to keep it and paint it a flat black. But be warned, this is not black by a mile. There is no angle or lighting that will make it look black.
