The first one came and it was wobbly. I could see that when it was put together the metal on one side where two pieces connected was not level. There was nothing I could do unless I wanted to take th chance of breaking it to try to straighten it out and not wobble. Wayfair sent another, which came bent on the side and I was able to straighten it out and it doesn't wobble. 
Thank you Waifair for replacing.
