So once you can manage to get this set together it seems sturdy. But man is it hard to set up!! 
It took my husband and I a couple of nights to complete because it’s been so hot and muggy outside. He had to hulk grip the seating and bars so I could get the bolt, washer and nut on. It was not pleasant and I would not ever recommend this set to anyone I like. There’s zero chance of a person setting it up on their own!
