This looked absolutely perfect on our  6' x 12ft deck. Unfortunately, the first hot day that we had it open, a sudden wind came up and broke it.  I think is was due to the exposure on our deck, rather than the construction of the umbrella itself.  We had it in a cast iron free standing base, which stayed put. The wind caught the umbrella and snapped it. However, it was expensive, so if we ever decide to try an umbrella again, we will not pay so much money.
