An offset patio umbrella, also called a cantilever umbrella or side post umbrella, provides cover without blocking your view. Since the support is off to the side, an offset umbrella is a practical solution for outdoor seating areas. A cantilever patio umbrella is also a great choice when a patio table umbrella is not an option. With their bright, weather-resistant canopies and sturdy construction, offset umbrellas can beautify decks, patios and poolside areas. Look for tilt adjustments and lighting features on some offset patio umbrella models.
