The pergola is very cheaply made but that was expected based on its price. Used in kind of a temporary installation for staging. It is incredibly unstable with no real way to actually bolt it down safely. We had to fabricate some steel baseplates that not only allowed us to anchor it to a concrete patio, but raise the entire pergola up by 12" so that it didn't feel so low. We also made some brackets to anchor it to the house so that it wouldn't just fold up and blow over. Other than that, it's a great piece!
