The end table and the coffee table are quite lovely and strong.
Update 8/13/20: the end table turned out to be not so strong and now we are worried about the coffee table. A bad weld in the connector of one of the vertical struts collapsed the table, pulling off the struts'  connector to the table-top. I wanted to save the table so I had all three struts re-welded. I called Wayfair and talked to someone who said a person would call me to answer one of my questions about re-attaching the connector to the glass, but no one ever called me. So I would say steer clear of both the end table and the coffee table with this dangerous design flaw.
