Very nice and sturdy. We have ours anchored to our concrete patio slab. It was a bit of a hassle putting it together even though my husband has experience with this kind of stuff…the instructions are confusing. Word of advice pieces may look the same but make sure you are NOT putting pieces together based on that fact and follow the letter coding to the tee. It does matter. Overall we are very satisfied and would buy it again. Worth the money.
