Christopher R. Arelt the umbrella is by shadescapes - it is the 'albatros' model and very large. I think it's around 14'x18' - it weighs a lot and the owners don't take the post down seasonally, fyi
However, if you want the umbrella to provide shade on a separate part of your patio — like over poolside lounge chairs — a freestanding design may be best. You could also just not want a pole to interrupt your patio table. “Freestanding umbrellas allow you to use a table completely for food space or game playing,” says D’Urso.
A tilted model helps to continuously block the shade as the sun makes its daily route from east to west.
To keep umbrella hinges in good shape while they're out in the elements, D’Urso recommends applying WD-40 and protecting the umbrella with a cover when it's not in use.
