It’s very heavy and solid, absolutely stunning, I’m very happy with the look of it.
I assembled on my own but would recommend 2 people as it has to be put together upside down so the marble bit needs to be held up to screw in place. Be careful with the legs on assembly as they did have some give so I feel like they could snap at the corner if pushed too hard. 
Only issue I had was that one of the legs didn’t have a protector on the bottom like the others and scratched my floor. Will have to buy one for that leg.
